Fake Hornet Nest

by Blake Newton, UK Extension Entomologist

Do you love hornets' nests, but hate the hornets? Or: do you love paper lanterns, but wish they were less-illuminated? A product has been developed just for you!

I just saw it on the Home & Garden Network this morning: it's a fake hornet nest that you can hang from a tree in your yard. It is supposed to repel hornets. The guy on the segment said that hornets are very territorial and won't build a nest within so-many meters of an existing nest. I don't know if this is true or not, but in an advertisement that I found for the product I read that "research has demonstrated that wasps are territorial and avoid other nests." Well, it certainly looks a lot like a hornet nest. It also must be made of the same kind of stuff (paper), because the guy on H&G said that you can't leave the fake nest in the rain or else it will disintegrate! On the other hand, real hornets' nests don't disintegrate in the rain (how do hornets make their paper water-proof?).

I'm not sure if there is just one brand of Fake Hornet Nest, or several, but here is an online ad that I found for one (it's sold out!).

Well, does anyone have any experience with these things? Do they work? Has anyone seen any research?

Tobacco Hornworm Locomotion

There was an interesting article in the New York Times on Tobacco Hornworm Locomotion. Here is the link:

2010 Raven Run Night Insect Walk

The 2010 Raven Run Night Insect Walk is coming up this week: 8:30pm, Friday, July 30. This is a free family event, hosted by the University of Kentucky Department of Entomology and the Raven Run Nature Sanctuary. Bring a flashlight and join us for a trek into the woods. We'll see all kinds of cool insects and spiders. And before the hikes begin we'll have free activities including an insect petting zoo, temporary tattoos, cockroach races, and other fun stuff.

Here are the details:

Icebox Cave Beetle

by Devin Kreitman, High School Student and 2010 KFELP Alumnus

Today, I found a beetle native to Kentucky that the government is considering putting on the endangered species list. The beetle is called the Icebox Cave Beetle. Here is a link to where I found the information:

Fun with scorpions

I purchased a scorpion after getting a Chilean Rose Hair Tarantula (Grammostola Rosa), because I realized that having only one arachnid just wasn't enough. After recieving my scorpion, I began to construct a terrarium with the scorpion's specific requirements in mind.Emperor Scorpions are rarely seen because they tend to hide under whatever they can, leaving their hiding place only to hunt. However, a few weeks ago I began to see the scorpion alot more often because it had constructed a burrow, with two of the sides of the burrow being the walls of the terrarium. This was very exciting, but couldn't compare to the excitement I felt the morning when I noticed that my Emperor was covered in what looked like white foam, which on further inspection, turned out to be none other than a little over a dozen baby scorpions (or “scorplings”).
I know a little bit about this large species of scorpions (pandinus imperator), and specifically, that the babies cling to the mother, who feeds them. From birth, they change from a ghostly white to the deep black of their parents. When they grow to adulthood I will have to break them up in to groups of two and keep them separated, or else risk cannibalism. Emperors have a 9 month gestation period (or 7 to 12 months depending upon temperature and humidity), which is a fact I find very interesting.For an aspiring entomologist such as myself, this is a great opportunity and I look forward to watching these amazing arthropods grow and flourish from tiny scorplings to adult scorpions.

New Things Discovered!

by Blake Newton, UK Extension Entomologist

I am the kind of person who pathologically clicks on CNN.com several times a day. I'm not sure what I expect to find there; all I get is reiterations of horrible news. My CNN fix: a habit that I would like to break. Except when they post one of their semi-monthly slideshows of newly discovered critters! I love these!

Usually, no matter where on earth these discoveries occur, there are some arthropods involved. This makes sense, since there are more kinds of arthropods on earth than all other organisms combined. And this time is no exception.

The geographic area: the deep ocean below the Great Barrier Reef in Australia.

Here's the slideshow:

There are several marine arthropods on the list, including some isopods and amphipods. My favorite is a very unusual isopod that has a typical pillbug-type body, but is also equipped with long spider-like legs. Isopods, by the way, also live in Kentucky: the familiar roly-polies that live around homes are examples of isopods. We also have amphipods in Kentucky: they are sometimes called "scuds" and they live in freshwater streams and ponds.

Thanks for the good news, CNN.com!

Lepidoptera Rap

by Megan Parker, Laurel County Water Pioneer

Float like a butterfly, don't sting like a bee
the lep-i-DOP-ter-A is easy to see

Butterflies, moths, caterpillars too
there's all kinds of colors, they could even be blue

Plants love caterpillars and moths galore,
make sure to listen up, and we'll rap some more

Coiled sucking mouthparts, scales on their wing,
they flyin' all around as me and Joe sing.

Thread-like antennae, knobbed at the end,
this rap is dope, we're sure to win

The Annotated Lepidoptera Rap: This rap was written by Megan for a contest that occurred during Water Pioneers. During the contest, each team was assigned one of three insect orders: Coleoptera (beetles), Hymenoptera (wasps, ants, bees), or Lepidoptera (butterflies and moths). Each of three teams was responsible for capturing three members of their order. They also had to become experts on their order and prepare and deliver a brief presentation to the other students. For their presentation, the kids could use almost any means of communication, including drawings, sculptures, skits, posters, and, of course, hip-hop. So this was another opportunity for Megan to write some lyrics for her MCs.

This rap does a good job of reminding the audience about some of the key Lepidoptera characteristics. Such as this key line: "coiled sucking mouthparts, scales on their wings." These are two of the most important features that distinguish butterflies and moths from other insects. And "they can even be blue" is a reference to a whole group butterflies commonly known as "blues" (one of them is pictured on the logo for this blog in the upper right-hand corner).

This activity is a good way to introduce students to the concept of scientific orders, by the way.

Oh, and Megan's group won the contest!
