Harwood Lab Amblypygid

A few posts ago, I mentioned the amblypygid that I spotted on an episode of Survivor. I forgot that one of our Entomology laboratories, the Harwood Lab, keeps it's very own pet amblypygid!

Kelton Welch, one of the lab members, manged to get a very good image of the creature as it fed on a cricket:



Close up:


Pretty fearsome looking, right? Actually, the creature is only about an inch long, and it is harmless to humans. It is possible to keep amblypygids as pets, but they require very specific conditions: high humidity, lots of crickets, and "vertical" hiding places (such as pieces of bark placed upright and stacked against each other). Here again is the link to the Wikipedia entry for these fascinating creatures.

Bugs-All-Day: April 16, 2011

Join us at the Explorium of Lexington on Saturday, April 16th, 10am-2pm, for Bugs-All-Day. Members of the University of Kentucky Department of Entomology will be there with live bugs, games, and other fun stuff.

April 16th will also be the grand opening of Small World, a permanent exhibit that the Explorium has created in partnership with UK Entomology. Small World will feature a variety of live critters, including a Chaco Golden Knee tarantula, giant millipedes, aquatic insects, and a giant centipede.

Admission to Bugs-All-Day and Small World is included with the regular Explorium admission price. Read more about the Explorium, including directions and parking information, at their website.

Survivor: Redemption Island -- Arthropod Watch

Blake Newton, UK Extension Entomologist

I'm still a Survivor fan after all these years. On this blog, I occasionally mention some of the critters that I notice on the show. At the end of last week's episode, I saw an amblypygid crawling on a tree during one of the night-vision segments. Amblypygids, also known as tailless whip scorpions, have a very strange appearance. To me, they look like the facehuggers from Alien. And some of them can get pretty big. They are basically harmless to people, though.

Amblypygids don't live in Kentucky, but they are found in some of the sub-tropical parts of the United States, like Florida. You can read more about these fascinating critters on this Wikipedia entry.

Bugs of Spring

Blake Newton, UK Extension Entomology

It's official: today is the first full day of spring! In Kentucky, that means mild, humid weather. And that also means bugs. This is bad news for some people, but for entomologists, it's a time for joy. It's also a good time for educators. Kids and teachers are typically trapped inside most of the school year, but spring is a time when some classrooms have an opportunity to get outside. And one of the easiest ways for a K-12 science class to take advantage of the outdoors is to study and observe insects. Insects are present in every kind of outdoor habitat, and they start appearing on mild days in early spring.

Recently, Scott Darst, (4-H Agent, Madison County Kentucky) called us and said that he was planning to take some kids outside this spring, and he wanted to know what kinds of insects you can expect to see on the earliest spring days. Here are some of them:

Butterflies. Some butterfly species overwinter as fully-grown adults (or spend the winter as pupa) and are ready to take advantage of wildflower-nectar on the first mild spring days. Some of the ones that I see in early spring in Kentucky are Commas, Question Marks, and some of the so-called Sulphurs and Whites. Yesterday, I saw one of the Whites (probably a Cabbage Butterfly).

Bees. Like butterflies, bees are pollinators, so they are ready for spring wildflowers, too. Honey Bees and several other types of bees are commonly seen on early spring days. Yesterday, I saw a large Carpenter Bee visiting daffodils in my yard.

Flies. Several types of flies are common in early spring. House Flies and their kin become active on mild winter days and early spring days to take advantage of carrion and other decaying materials that begin to thaw as winter comes to an end. Crane flies breed in cool wet areas, so spring is a time for them to thrive.

Spiders. While spiders are probably most-commonly noticed in late summer and early fall in Kentucky, there are several types that are active as soon as mild temperatures return in the spring. Furrow Spiders are one of the few types of orb-weavers that overwinter as adults, and they can be seen making webs in spring. I have also already seen a Bold Jumping Spider this spring. These large jumping spiders are also able to live through the winter as adults.

Others. Although the critters mentioned above are among the most noticeable early-spring insects, there are many more that you might encounter, too. Ants are already moving in Kentucky, and so are some of the wasp species. I have also seen a Boxelder Bug. Also, aquatic insects (like mayfly and stonefly naiads and caddisfly larvae) thrive in cool water, so spring is a great time to find them if you are willing to get a little bit wet!

So get out there and hunt for some bugs. If it's a sunny day and the temperature is above 50°F, I guarantee that you will find some, and it's also pretty likely that--even though bugs are involved--you'll have a better time than you would sitting inside!

Go Spiders!

The Richmond Spiders men's basketball team is currently playing in their conference championship game. They did well last year, too. I'll continue to cheer for them until they have to play UK!

The Spiders have a lame mascot:


But a very cool logo:

Zombie Fungi

Here's a link to a cool story, including a video, of fungi that parasitize insects and turn them into "zombies."

http://www.huffingtonpost.com/2011/03/02/zombie-creating-fungi-cordyceps_n_830558.html

Although these fungi don't actually reanimate dead insects, they do have the ability to influence the behavior of their hosts. A fungi-infected ant, for instance, will engage in behaviors that will make it more likely to spread the fungus to other members of its colony. Imagine if--when you were sick with the flu--you had an uncontrollable urge to walk up to people and sneeze on them!

Although the specific fungi mentioned in the article are newly-discovered, this phenomenon has been known in insects for a long time. In addition to fungi, some viral diseases are also able to affect similar zombie-style behavior in their insect hosts. Luckily, none of these diseases are able to infect humans!

Mazda Spyder

Mazda is having problems with spiders. As it turns out, the "evaporative canister vent line" in their Mazda 6 sedan is a perfect habitat for Yellow Sac Spiders. These spiders like to take up residence in tiny, tube-like spaces, so this isn't too surprising.

Here is the story from CNN:

Yellow Sac Spiders, by the way, are very common in the U.S. They are often found in homes, and are sometimes mistaken for Brown Recluse Spiders because they have a similar shape. Read more about Yellow Sac Spiders.

UPDATE: A journalist from L.A. just called us to ask some questions about this story. I told him that I'm not really an expert on Yellow Sac Spiders, but I gave him the best info that I could. Can't wait to see if my name shows up in a report!

ANOTHER UPDATE: Quoted in USA Today. Cool!
