The Most Common Garden Spiders Are More Interesting Than You Think

Tuesday, March 14th, 2017

If you do any gardening in your spare time then you probably have a love hate relationship with insects. That is understandable since some insects can devour or kill your garden while other types of insects can prevent garden damage by devouring those pesky insect-pests. But have you ever tried identifying some of the spiders that you find crawling about your garden? Some are scary looking, but very few, such as orb-weavers and harvestmen, are harmless.

The biggest spider that you will find in your garden will most likely be a golden orb-weaver. The GOW dwells in the south and is known for the golden hued webs that they weave. If you have ever spotted a web that appeared to be golden in color, then it was certainly created by the enormous golden orb weaver. There is no reason to fear these behemoths if you find them crawling in your garden since their venom only feels like a bee sting. Only if you are allergic to bee stings should you run from this scary looking spider. However, the GOW is also hesitant when it comes to biting, and they are often handled for long periods of time without injury by spider enthusiasts.

You are also likely to spot both harvestmen arachnids as well as the well-known daddy long legs arachnids in your garden. There are many myths about both of these often-mentioned arachnids, and they are not spiders. Rather these arachnids are distinguished from spiders in that they possess only two eyes and a one-piece head and thorax. These arachnids are also quite distinct from spiders in that neither one of these species of arachnid spins silk, they are not venomous they are not predators and they often resort to scavenging for sustenance. Harvestmen arachnids are nothing to fear as they are largely nocturnal and prefer to avoid contact with all animals by dwelling under logs or pieces of wood that you might find in your garden. If you find one, toss it in the yard; it will survive.

Have you ever sustained a bite wound from a spider or an arachnid that was dwelling in your garden? If yes, what type of spider or arachnid bit you?

Is The Red “Hourglass” Mark On Black Widows Meant To Frighten Predators?

Friday, February 10th, 2017

Black Widows are well known around the world. These spiders are especially known in the Americas for having a highly venomous bite, they are generally intimidating to other arthropods, and the females often kill their male counterparts after mating. And the red “hourglass” marking on the female’s abdomen is a sure indicator that the female black widow is poisonous, right?

Although the strangely shaped red markings located on female black widows has made them famous, what is its actual purpose? Many people have heard that the markings are there to indicate to humans that black widows are venomous. That would be a very gracious tip from Mother Nature herself if only that were true, but it is not. Actually, the red markings located on a female black widow’s abdomen are meant to intimidate, but not all animals are so scared.

According to scientists, as of now we know that the red markings located on the female black widow’s abdomen can effectively scare birds away, but not insects. In fact, it is likely that insects don’t even perceive the hourglass shape in the first place. The visual systems belonging to birds and insects are very different systems. Birds have extra photoreceptors that allow them to perceive the red color on a black widow; an insect cannot boast this remarkable vision. So, now you can just say that the red hourglass marking that you see on a female black widow’s abdomen is for the birds.

Have you ever spotted any type of spider or insect that possessed a brightly colored feature that made it stand out?

Honey Can Actually Help Heal a Brown Recluse Spider Bite Wound!

Wednesday, October 26th, 2016

The bite of a brown recluse spider can spell very bad news for the victim. Their venom is extremely poisonous, more so than that of a rattlesnake. It is especially toxic to cells and tissue. When the venom is released into the skin it begins attacking the tissue. The venom is able to break down the skin, fat, and blood vessels. This eventually leads to tissue death or necrosis around the site of the bite. What makes the brown recluse’s bite even more dangerous is that it often goes unnoticed because the bite is usually painless. Symptoms don’t usually begin to develop until 2 to 8 hours after the bite occurs.

Amazingly, there is one natural ingredient that has the ability to actually heal the wound from a brown recluse spider bite. Honey has incredible wound healing powers, and can help heal everything from burns and bacterial infections to serious spider bites. Now, not just any store-bought honey works, however. It must be pure, raw honey, and manuka honey tends to work best. Manuka honey can release hydrogen peroxide, which is essential in the elimination of bacteria. Manuka honey specifically has been known to heal serious infections.

To properly utilize its healing properties you need to make sure you apply the appropriate amount of honey, spreading it evenly over the wound. What works even better is to spread the honey over a wound dressing and then wrap it around the infected area. There are even pre-packaged wound dressings that are made with honey contained inside them.

Have you ever tried using honey to help heal a wound? How well did it work for you?

Frankenspider: A Long Extinct Spider Walks Again!

Thursday, June 23rd, 2016

An extinct spider called Paleocharinus has been recreated via digital imaging.  The extinct spider crawled the earth 416 million years ago.  These spiders are interesting because during this time most of the Earth’s species dwelled in the ocean, and the Paleocharinus was among the first bugs to walk on land.  In fact, they were about the only animal at all to walk on land during this time, which made them the species at the top of the food chain.

The team of researchers and computer graphics artists were only able to recreate the bug while walking due to how well preserved it was within a fossil.  The researchers could even make out the muscle tendons of the bug, which was instrumental in recreating how it moved and attacked other species of tiny bugs that existed at the time.  These bugs even walked much like modern spiders, but due to the creation of modern giant bugs, the life of this extinct bug was short lived.

What other extinct bugs do you know about? What were they like?

Spider Super Glue

Spider Super Glue

Professor of biological sciences at Virginia Tech Brent Opell has put together a research team to study the glue spiders create for their webs. Spiders create this glue when the glycoproteins secreted from their abdomen interact with the atmosphere. Scientists want to use this glue to create better, more environmentally friendly adhesives. But first scientists must understand how it is made, as well as it capabilities and limitations.

Opell’s research team have recently found that UVB rays play an important role in how well the spider’s webs work. After testing the webs of five different species of spiders, the team found that the webs of spiders that hunt during the day were much more resistant against UVB rays. This find is crucial to creating adhesives that are environmentally non-toxic and energy conservative. These new adhesives will be inspired by the spider thread glycoprotein. They will prove much more resistant to UV rays than current adhesives, which degrade at a much faster rate when exposed to UV rays. The chemistry of spider glue will vastly improve our ability to produce heartier adhesives.

What do you think of using spider glue as an adhesive? Do you think this is a big step towards making a superior adhesive product?

Hobos Spider are invading! | Spider Control

Hobos are invading!

Experts in Kalispell are overrun with an influx of hobo spiders. After placing glue strips down to catch the pesky spiders, they have found 30-40 spiders per strip. Experts are blaming the unusually warm weather this year on the invasion of the hobo spiders.

Hobo spiders sometimes can be confused for brown recluse spiders because of their appearance. While they are brown in color, their chevron shaped markings give them away.

The hobo spiders make their homes in ground vegetation and wood piles, sometimes moving a housing structure near leaky windows or door frames. Experts say that this species of spider not only enjoys but adapts well to changing climates. The hobo spiders tend be out of the nest searching for food and also matting at an aggressive rate.

Bites from the hobo spider are not fatal but can cause uncomfortable reactions. Those reactions include a pens and needles feeling at the bite site with a small, hard area appearing after the bite. This area may become numb. Sometimes the bites will turn into a lesion that blisters that can be quite painful and don’t heal in a timely fashion.  Experts say that about half of the time hobo spiders don’t release venom when they bite so no symptoms at all would appear.

CNN Money: Spiders lead to Mazda recall

Spiders lead to Mazda recall

NEW YORK (CNNMoney) — Mazda is recalling about 52,000 Mazda6 sedans in the U.S., because yellow sac spiders like to build their nests in part of the fuel system.

“A certain type of spider may weave a web in the evaporative canister vent line and this may cause a restriction of the line,” Mazda said in a letter to the National Highway Traffic Safety Administration.

The evaporative canister vent line runs from a charcoal-filled canister that cleans air coming out of the gas tank. Blockage of the line can prevent air from getting into the gas tank as the gasoline is used, resulting in negative air pressure inside the tank. That can lead to a crack in the gas tank and the possibility of a fire.

There have been 20 reported cases of spider infestation in the Mazda6 — all have been in cars with 4-cylinder engines, none with V6’s. No actual fires are known to have been caused by the spiders, according to Mazda’s letter.
