California Has Fireflies! Who knew?

What better time to start planning a summer vacation than in the middle of a cold (sort of), wet California winter.  If you are doing a little California dreaming right now, why not plan a summer adventure in the beautiful southern mountains.  You might be surprised at what you find.  Like Joshua Oliva, who recently completed his undergraduate studies at UC Riverside, who discovered a brand-new species of firefly while exploring in the Santa Monica mountains, in Topanga. firefly-2466543_640

This tiny creature with its glowing personality, was only about half a centimeter long and it did faintly glow. He (she) has a long way to go to measure up to its East Coast relatives, who, by the way, are larger, more numerous and really, light it up, on warm summer evenings.

Contrary to popular belief, California is home to 18 species (soon to be 19). In contrast, Florida has about 56 species of fireflies. Fireflies are nocturnal members of Lampyridae, a family of insects within the beetle order Coleoptera, or winged beetles

Firefly larva, also known as, glow worms live for about one year, before it turns into an adult and mates.  The average lifespan of adult fireflies is around 2 months. The firefly’s sole purpose in life is to mate and procreate. Flashing each other, the males and females, find the loves of their lives.

In the United States, it’s extremely rare to see glowing fireflies, west of western Kansas, and even the ones that do glow can be very small and their light so faint that it can hardly be seen. But here’s the scoop.

Luminescent fireflies also known as lightening bugs, have been seen in the Santa Monica mountains and the Laguna mountains in San Diego.  They’ve also been spotted on the southeast slope of Mt. San Jacinto and upper Lytle Creek in San Bernardino County.

In general, fireflies prefer wet, humid habitats that  support their favorite food, snails. Those few species that have been discovered in Southern California have been found mostly by ponds, springs, seeps and streams.

  1. They have strange eating habits. Contrary to the cute image of baby fireflies flitting from flower to flower, the underground-dwelling larvae of the lightning bug are carnivorous and feast on oozy slugs, worms and slimy snails. Once they grow up, some turn to cannibalism and eat other fireflies, but most live on pollen and nectar (while some don’t eat anything during their short lifetimes).
  2. Predators that might crave a “light” meal, beware the lightning bug. They taste disgusting. Firefly blood contains lucibufagins, which is a defensive steroid that tastes really yucky. Predators associate the awful taste with a firefly’s light and learn not to eat bugs that shine.mason-jar-2-3864319_640-1

If your summer, mountain adventure includes firefly hunting, your best bet is to grab a mason jar (don’t forget to poke holes in the lid) and head for an area with a natural water source on a warm summer night. Turn off your flashlight, so you can see their glow.  Be thoughtful.  When you are done admiring these little guys, let them go.  They will thank you for it.

“It’s not The Planet of the Apes—it’s The Planet of the Arthropods.”

 

Who are the most successful beings on Earth? It certainly isn’t Man, Ape or any other mammal. The most successful animals on the planet are the arthropods. They have conquered land, sea and air, and make up over three-fourths of all currently known living and fossil organisms. They are the true masters of the Earth!

Various Arthropods Wikipedia Commons
Various Arthropods Wikipedia Commons

The Phylum Arthropoda got its name from the Greek, arthros (jointed) and poda (foot) and encompasses over 800,000 species, including arachnids (spiders), crustaceans (sea creatures) and insects.  Also, members of this gigantic phylum are Myriapods; centipedes, millipedes, sea spiders, and maybe a host of other organisms yet unidentified.

What do all of these creepy, crawly and flighty creatures have in common?  They are all invertebrate (without a backbone), have symmetrical, segmented bodies, jointed legs, exterior skeletons, a ventral (front) nervous system, highly developed sensory organs and they are cold blooded.

Arthropods have a leg up on all other organsms. They do everything with legs or modified legs. They swim, crawl, jump, and fly, they use legs to sense with (their antennae), to bite and sting with and to chew with (they even chew sideways).  All this and more, is done with legs.

So, with segmented bodies that accommodate environmental changes, with legs that let them walk; with hard, waterproof shells that keep water in or out; and with highly adaptable respiratory systems, arthropods have dominated the animal world.

Arthropods occur in virtually every earthly habitat, from the cold ocean depths to the hottest deserts. They can live through extremes that would kill most vertebrates.

Fun Facts about Arthropods:

  • Arthropods crawled onto land about 100 million years before vertebrates did. It’s thought that colonizing land was easier for them for several reasons – including the fact that they had already evolved legs, which they used for walking on the bottom of the sea.
  • About 80% of all animal species are arthropods!butterfly-emerging-from-cocoon-1518060_640
  • All arthropods undergo metamorphosis – a process where their bodies change radically as they pass from their larval to adult stages. Butterflies are the best-known for entering cocoons as caterpillars and coming out quite different, but all arthropods do something similar!
  • When arthropods outgrow their old exoskeleton, they molt – leaving behind their former skin and growing a new one. All arthropods do this at least once in their lives.
  • Crustaceans and arachnids – two types of arthropods – have blue blood instead of red blood! Their blood uses a blue copper compound to carry oxygen, instead of the red iron compound used by most other animals.
  • An Arthropods’ hard exoskeleton is made of chitin – which is made of a sugar glucose compound! It’s not sweet but it sure is hard!

If all mankind were to disappear, the world would regenerate back to the rich state of equilibrium that existed ten thousand years ago. If insects were to vanish, the environment would collapse into chaos. (E. O. Wilson, The Diversity of Life)

Christmas Crashers

There’s nothing like the smell of an evergreen tree and a cozy wood fire, to get you in the holiday spirit. But when you bring a live or cut Christmas tree indoors, along with the necessary firewood, some of the insects tspider-found-in-holiday-decorationshat have called your Christmas tree and yule log, home, might be joining you for the holiday season.

Aphids, bark beetles, bark lice, spiders and, even termites may be homesteading your Christmas tree.   Most of the Christmas trees you pick up from a lot or other

commercial settings are utree_farm_christ_trees_12-8-12_8298288388sually inspected and cleaned. The emphasis here is on usually. The greatest threat of home invasion comes to those who cut down their own trees.

It is a known fact that as soon as a tree is cut from its trunk and brought into someone’s warm home, most hitchhiking critters die from starvation or desiccation (lack of water).termites-eating-wood-and-swarmers It’s also a known fact that some may begin to wander from the tree, or firewood pilewood-pile, in search of food and water sources and if these are found they may start to set up housekeeping.

Don’t be afraid to purchase a real tree because of the possibility of tiny pests. And don’t forego the warmth and cozy atmosphere of a wood fire either. Control methods are relatively simple and low maintenance. And remember, artificial trees can house pests, too.

Spiders Spin a Web of Fear!

Spiders and their webs are synonymous with Halloween.gothic-2487365_640

Spider lore has changed over time.  According to medieval superstition, people believed that if you saw a spider on all hallows eve, it was the spirit of a dead loved one watching over you.  When humanity started the witch hunt era, spiders became associated with magic, witches and the supernatural, right along with bats and black cats. They also become representatives of danger, fear, ensnarement, and deception (think of the phrase “caught in a web of lies”).

Their odd anatomy and physiology (multipwolf-spider-eyes-and-fangsle eyes, crushing mandibles, 8 legs, and bulbous abdomen) creates aversion and fear in some individuals. brown-hairy-spider

Add in their habit of seeking out cracks and crevices to hide in, their skittering and jumping movements and their nocturnal foraging activity, not to mention their ability to create great sticky webs, and what you have is the basis for “arachnophobia, or the fear of spiders.cobweb-74592_640

So now that we are convinced that spiders are loathsome creatures, our imaginations add magnitudes of size and deadliness, making them truly Halloween icons.

The true nature of spiders isn’t to be scary.  But if you are perceived to be scary, then nobody messes with you, hence you may live longer.

Spiders have acquired a bad reputation over the centuries.  Going from lucky charms to fearsome, evil specters.  What they really are, are natures clean-up crew. wasp-spider-3659351_640                                        Spiders eat other insects.    Their diet consists mostly, of flies, roaches, moths, earwigs, aphids, caterpillars and even pesky mosquitoes.  Some of these delicacies, spread disease, so spiders help humanity stay healthy.

While we faspider-man-1242398_640ntasize spiders into huge, deadly, horror creatures, remember they are also the inspiration for a much beloved super-hero, Spider Manspiderman-1341591_640 

You may be noticing more spiders out and about. It’s Fall, otherwise known as Autumn, and this is the time of year when many male spiders are out searching for a mate. This is true for house spiders and garden spiders, alike. If you are seeing more spiders inside your home, they may have came in from the cold, but more likely that they have been hiding in your wall voids all summer, venturing out, now into your living areas looking for mates.  Once they mate, chances are, the males will die and the females will go back into hiding, lay their eggs and then, you know, “die”.

It’s Rodent “Beware-ness” week: “Batten Down the Hatches”!

Fall is a time of change.  The weather is cooling, leaves are falling, plants and animals are going into overwintering mode and for animals this means heading out of the landscape for safer, warmer places, like inside your home, inside your car or inside your BBQ (not to mention inside pool equipment cabinets).

 

The most frequent unwanted visitors, this time of year, are Mice and Rats.mice-on-cornRat yelling

 

Besides being disgusting, noisy and destructive, rats and mice can contaminate food, spread diseases, bring on allergies and even invite their friends; fleas, ticks and lice into your home.  Rats, especially, have been known to greatly damage property by chewing through drywall, insulation, and electrical wiring (including vehicle wiring).  If you park your car outside, don’t forget to check under the hood frequently.

Prevent rats and mice from making your house their home by:

  • Removing yard debris and trash. Always look for places you think rats might like to live such as wood piles and thick ground covers. Take time to thin out the vegetation and move firewood away from the home. Frequently restacking the wood will also discourage rodents from the area.
  • Keeping trash cans tightly closed. rat-in-trach
  • Storing pet food or bird seed in metal cans with secure lids.
  • Picking up fallen fruit. (Don’t feed the rats!)
  • Bringing in pet bowls and bird feeders at night when rodents are the most active.
  • Keeping your home in good repair. Check for openings where rodents can get in. Remember that a mouse can squeeze through a hole as rat_pipesmall as a dime, and rats can enter through quarter-sized holes. Covering the openings with metal, concrete or mesh wool or copper mesh wool will stop them from getting in.

Rats and mice are sneaky, determined  creatures, so if they’ve gotten past your best defensive line, it’s time to call in the professionals.  

Fun Fact:

Rats and mice have a need to gnaw. rat-at-dentist-1_k2puy3y6fb6ohq-5csefw

They’re not looking to add wiring or building materials to their diet, they are doing what they need to do to promote good dental health.  Yes, rats gnaw to take care of their teeth.  Their front teeth constantly grow and without gnawing and chewing to reduce the size of their choppers, the teeth would grow right out of their mouths until they would be unable to eat therefore starving to death or the bottom incisors would poke through the roof of the mouth stabbing into the brain. Not a good way to go.

Argentine Ants and Chemical Warfare

In their quest for world domination, Argentine ants have successfully conquered 6 continents and many islands.  How did they do this?  Easily, their multi-queen colonies, adaptive abilities (conquering changes in their environment) and their nomadic lifestyles), have made them “hard to kill”.

1st-american-ant-colony

The first Argentine ants disembarked, in New Orleans, from ships carrying coffee from Brazil. Originating along the banks of the South American, Parana River, in a tropical ecosystem, Argentine ants have become a major nuisance in the southwestern United States including California.  They are now thriving in urban areas where non-native landscape and plenty of irrigation fosters beautiful tropical environments.  As an invading species they are a natural and economic threat to native ants by aggressively competing for life sustaining resources and pollinators by protecting plant pests such as aphids and scales that provide them with a food source, honeydew, while the makers of their food source destroy landscape plantings and crops.

By Penarc {http://en.wikipedia.org)
By Penarc {http://en.wikipedia.org)

Being extremely aggressive, these ants out compete native species for food and other resources by employing “Chemical Warfare”.  During battle, Argentine ants produce secretions that serve them in two ways, first they irritate and incapacitate their foe and second, this same secretion attracts other Argentine ants to the war zone where they aggressively join the battle.

A single colony may contain 10,000 female workers, and there may be hundreds of colonies around your home; the total number of ants could easily reach a million. Although they cannot sting, they can and do bite.

Native ant colonies, for the most part, are extremely territorial and will fight other colonies of the same species. Argentine ants in the United States are all closely related with very similar DNA, since originating from the first colonizers in Louisiana. They seem to accept ants from different colonies as members of their global family. It has even been observed that, Argentine ants from different colonies will “join forces” and attack together in huge swarms. To Argentine ants, victory is simply a numbers game and they don’t care if the enemy is Goliath and they’re David.

In their case, size doesn’t matter. It’s not the size of the ant in the fight it’s the size of the fight in the ant and maybe who has the best weapons.

They’re Out for Blood!

mosquito-swarm-red-dawnA new “Red Dawn” is here. Invaders from all over the globe are taking over our neighborhoods and these guys and gals “Bite” and “Suck Your Blood”.  The newest of the bunch is the aedes-noto-2Aedes notoscriptus, the Australian Backyard Mosquito.  Joining the other two invasive, non-native, Aedes Mosquito species (aedes aegypti and aedes albopictus) this hungry mosquito is plaguing Southern California and together with its’ companions is bringing the risk of disease (Zika virus, dengue fever, yellow fever, chikungunya and in dogs, heartworm).

The Aeaedes-albopictus-1des albopictus (the Asian tiger mosquito) arrived in California in 2011 and the Aedes aegypti (the yellow fever mosquito), in 2014. The newest arrival, Aedes notoscriptus has been aedes-egyeptiidentified here since early 2017 and its’ populations are increasing exponentially, (that means really fast) due to the hot humid weather we have been experiencing.

Back yard breeders and daytime feeders.

Females of this dark colored mosquito, with outstanding lighter markings, banded legs, and a white band across the proboscis, bite humans chiefly by day in shaded areas. These mosquitoes don’t fly very far, so much of their spread has been helped by the transport of their eggs in everything from flower pots and old tires to trains, planes and automobiles. They are known to prefer breeding in container environments.

Being extremely tiny and aggressive, people never see what’s biting them, leading to misidentification of the attacks as coming from spiders, bed bugs, sand flies or fleas.

Their bites, often concentrated on ankles and legs below the knees, look like clustered pinpricks. They quickly become red and inflamed and grow into big red welts and rashes with scratching.  These bites seem to be extra itchy and that can be because our immune systems haven’t gotten used to them yet.

According to vector control officials, these three species, lay eggs on the sides of barrels (and other containers), not just in standing water, so even though you dump out the water, they can remain alive (and in wait) in people’s yards for years.

Keep safe from mosquitoes by following a few rules.

 In your yard and around your house:

  • Decrease watering schedules                        yard work
  • Remove standing water
  • Limit outdoor activities when mosquitoes are most active.
  • Cut back (prune) dense foliage
  • Mow tall grasses
  • Fix broken screens
  • Move outdoor lighting away from windows and doorways
  • Burn citronella candles or torches on or around the patio or other outdoor areas where activities are being performed.

When you don’t have the time or the inclination to implement the needed procedures to safeguard your landscape plants and gardens from mosquitoes, considegetting help from a professional pest control company and have them, do the work for you.

When you are outdoors: mosquito repellant spray

  • Limit outdoor activities when mosquitoes are most active.
  • Wear protective clothing (long-sleeved shirt and pants).
  • Use a proven effective mosquito repellent (products containing Deet or oil of lemon and eucalyptus)

Why Do Mosquitoes Love You? They think you’re HOT!

The two most dominant factors of mosquito attraction have to do with sight and smell, so there’s no brushing these guys (oops! Girls) off when they’re out looking for a quickie in the moonlight.

Here are four reasons a  Mosquito may pick you for the love of their life.

Your Fresh Breath

Woman Summer Dandelions Freedom Blowing Wind

Mosquitoes don’t bite randomly. Instead, they find a victim by following their steady output of carbon dioxide.  Researchers say that mosquitoes are adept at figuring out where their target is by following trails of exhaled carbon dioxide.

Unfortunately, there is no way to cut down on your carbon dioxide emissions besides holding your breath. So, if you are being bitten you might want to head indoors.

Your Hot Body

While carbon dioxide is how mosquitoes lock onto you as a target, heat may be how they figure out the best place to bite you.

Dr. Jonathan Day, a professor of medical entomology at the University of Florida, tells us that before mosquitoes can take a bite they have to find an area of the body where the blood is closest to the surface. Common areas include the forehead, wrists, elbows, neck and ankles.woman-sweating

With the ever-increasing number of people keeping fit by exercising out of doors, mosquitoes are having an easier time finding what they love most, blood. Those who are over heated or who have just finished working out will have blood closer to the surface of the skin throughout their body. Faster respirations and an increase in carbon dioxide output identifies “Prime Targets” for love starved mosquitoes.

Exercising outdoors at dawn or dusk (prime time for mosquitoes) also ups the risk for more love bites.

Although a few small studies have speculated that mosquitoes were after specific blood types, the CDC says that’s false. By the time the mosquito bites you, they’ve picked you as their target.

Your Cool Outfit

Black may be the best color for a fashion statement and it’s great for hiding body flaws but it’s the worst for hiding from mosquitoes.

If you’re heading to an outdoor event and looking to avoid becoming a mosquito’s meal, avoid anything in dark denim or all-black outfits because some mosquitoes are visual hunters that search you out by looking for signs of life against the horizon. If you dress in dark colors, you stand out against the horizon and mosquitoes can see you.

Your Party Spirit

Human Festival Celebrate PartyWhen you drink alcohol, your blood vessels dilate, increasing blood flow to the surface of your body. You may feel a flushed, warm feeling.  This increased blood flow makes it easier for a lovesick mosquito, to target you.

Movement can also draw these biting insects in, so gyrating party dancers and avid hikers on the move should wear plenty of bug-repellent.

Fact:

mosquito-no-more-deetEven though DEET has been the recommended repellent of choice, there are still those who look for a more natural solution to stop mosquitos from biting.  According to the CDC, lemon eucalyptus oil could be a much safer and more natural solution.  The CDC confirmed that lemon eucalyptus oil can be as effective as DEET in repelling mosquitoes.

TARANTULAS ARE LOOKING FOR LOVE EARLY IN SOUTHERN CALIFORNIA

Male tarantulas have been spotted, early this season, marching in mass for mates.  This annual march to find love, usually starts around September or October, but rangers in our state parks believe that the weather has male tarantulas starting their searches earlier this year. follow-the-spiders-2

Despite their fierce reputation and scary demeanor, the 29 species of tarantula that are native to the United States are mostly harmless. These spiders have large fangs and a bite will probably hurt, but their venom, which is relatively mild, rarely causes a reaction in humans.  It would be more likely that an allergic reaction occurs from coming into contact with the “urticating” hairs” that these spiders kick at predators and prey. These hairs can get into the nose and eyes and cause a lot of discomfort.

Tarantulas are slow and deliberate movers but accomplished nighttime predators. Insects are their main prey, but they also go after larger game, including frogs, toads, and mice. They are mostly burrow dwellers and do not use webs to capture prey, but they do spin a trip wire to alert them when something nears their burrow.

These spiders grab with their long, strong legs, inject paralyzing venom, then kill their unlucky prey with their fangs. They then secrete digestive enzymes to liquefy their victims’ bodies so that they can suck them up, like a milk shake, through their straw-like mouth openings. After a large meal, the tarantula may not need to eat for a month.

tarantulas_meetA male, encountering the silk surrounding the entrance to a female’s burrow, calls and dances suggestively. He may be rejected or selected, and after mating he may  even be eaten, becoming a ready-made source of protein to jump start the development of the next generation.

Although spiders are world class predators, they are often themselves eaten. Tarantulas have lots of natural enemies, including lizards, snakes, birds, and even wasps. A female tarantula hawk (a large wasp) can locate a tarantula, sting it, and then drag its paralyzed body into a previously prepared burrow. Inside the burrow, she lays a single egg on the body of the living spider. When the larva hatches, it eats the tarantula!
tarantula-bobSan Diego County has two species that call it home – The California Black or Ebony (Aphonopelma eutylenum) and the San Diego Bronze (Aphonopelma reversum or steindachneri).  Both have bodies about 2 inches in length and neither are aggressive.

If you look up the meaning of Tarantula, you’ll find that it doesn’t mean, monster with eight legs or giant killing machine.  It means, “Big Hairy Spider”.  That is exactly what they are.

Fun Fact:

The name Tarantula apparently originated in the 14th century, in the Italian city of Ttarantella_napoletana_1870aranto, where people felt compelled to dance the sweaty, wildly gyrting  “Tarantella, when bitten by a spider. They believed to do this dance was the only way to cure themselves of the deadly effects of the bite.

Giant Rats: From Nasty Vermin to Super Heros

 

Giant RatScary Rats:  Giant rats are no longer just figments of the imagination.  Now, it seems, these once mythical rodents are in fact real, and they’re absolutely, ginormous. That’s really, really big!

A rat, which was called “Vika” by locals on Vangunu (one of the many islands making up the group known as the Solomon Islands) solomon-islandswas for decades the stuff of legend. It wasn’t until a logging company (in 2015) accidentally flushed one from hiding, while clearing trees, that the Vika stories changed from fiction to fact. Then in 2017, researchers were able to hunt one of the rats down and through DNA testing found that this huge rodent, was a brand new species.

Now known as Uromys vika  , this rat has orangish brown fur, measures a foot anvika-ratd a half long and weighs more than 2 pounds. To put that in perspective, the average rat in the US., tops out at about 8 ounces with a body 7-11 inches long and tail another 7-9 inches. This new rodent, thought to be strictly herbivorous (plant eating), feasts mainly on nuts whose shells are thicker than that of a coconut. The animal’s massive teeth easily gnaw through the outer layer of the nut to make a meal of its tasty insides.

Another Giant Rat species, the Bosavi woolly rat is one of

From Wikipedia

the largest rats, according to the Smithsonian Institution. A Smithsonian biologist discovered this new species of giant rat in 2009 in the crater of Mount Bosavi, an extinct volcano in Papua New Guinea. It weighed close to 3.5 lbs. and measured 32 inches long, including the tail. This gigantic rat has a thick silver-gray coat and was not unafraid of humans. According to researchers, this species may only live inside this volcano.

The African or Gambian pouched rat,  Cricetomys gambianus, (is also on the exremely large side. It weighs between 2 to 3 pounds and grows to around 3 feet long (including its’ tail).  In its native Africa, the pouchedgambian-rat-standing rat lives in colonies of up to twenty, usually in forests and scrub areas, but also very often around termite mounds. It is omnivorous, preferring palm fruits and palm kernels while also feeding on vegetables, insects, crabs, and snails.  It is not a true rat but is part of an African branch omuroid rodents. It derives its name from the pouches inside its mouth (in the cheeks) that are used to store extra food.

For all it’s scary and perceived nastiness this rat rates right up there master-splinter-action-figurewith the famous “Master Splinter” of Ninja Turtle fame for his save the world attitude.  Known universally as the Hero Rat” for its work as a trained landmine detector and in the medical field for its ablity to detect, sniff out tuberculeosis ,.

Since 2000, these rats have cleared mine fields in Tanzania, and detected 6,693 land mines, 26,934 small arms and ammunitions, and 1,087 bombs across hundreds of miles in Mozambique. They’re also hard at work in Thailand, Angola, Vietnam, Cambodia and Laos.
