International Rock Flipping Day: Results 2011

Did you flip a rock today? Below are photographs of what I discovered. As soon as I get linked up with Wanderin’ Weeta, I will post a list of the participants so you can see what everyone found.

The rocks:

A pile of what we call “river rocks” used to stabilize a drainage area. This particular area is mowed grass, so it is irrigated often.

You would expect to find an isopod (also called rolypoly or pillbug), after all there’s one on the International Rock Flipping Day badge.

But what is that with the isopod?

What is that brownish coiled object in the lower right of the photograph?

It is a tiny snail! There’s another with its head out.

It’s blurry, but definitely a snail. Finding snails is amazing in this hot, dry climate.

The snail wasn’t the only one carrying it’s house.

What is the gray object that looks like a small tube of mud? It is moving!

There is some sort of insect larva inside.

I think it is a beetle larva carrying a case. It is most likely a member of the leaf beetle family (Cryptocephalinae). It probably got washed to the drainage area during a recent storm.

Another tiny beetle scurries away.

Mites were common. Here’s a brightly colored one.

Spiders were also abundant. This tiny jumping spider seems to have its eyes on something.

Maybe it was trying to catch one of these Indian house cricket nymphs.I don’t envy any predator that hunts these.

I know I had trouble capturing them with my camera. The springtails that were everywhere were even worse. I never did get a photograph of them.

Finally, I did find some ants. I posted those results at Wild About Ants.

Overall, I was pleasantly surprised by the number of creatures I found. And in addition to finding different kinds, I also learned a little bit more about my neighbors that live under rocks.

Did you flip any rocks this weekend? What did you find?

Bug of the Week: Giant Mesquite Bugs

Related to the squash bug from last week, this week we found giant mesquite bugs.

These big bugs (about the size of a child’s thumb) seem like something from another age.

Let’s look closer.

I can tell this is a “true bug” because of the triangle in the middle of its back. Can you spot it?

Also, look how the wing changes texture from where it attaches on the back (at the right side) to between the water droplets. The wing veins run in another direction and the wing actually goes from leathery to more flimsy, like a piece of cellophane.

Let’s go back  to look at the squash bug. Can you see the triangle and the wing patterns, too? In this case the triangle is not a different color, but it is still there.

Those are clues entomologists use to tell if two insects are similar, and also what kind they are.

Squash bugs and giant mesquite bugs are alike in other ways, too. It turns out that the giant mesquite bugs will also produce odors to defend themselves.

In this photo you can see the mouthparts sticking down below the head. Giant mesquite bugs use their “beaks” to suck plant sap from mesquite trees. (The adults we saw were clustered around the green seed pods of the mesquite trees.)

Firefly Forest has photographs of the bright-colored immatures (nymphs) and more information.

Have you ever found a giant mesquite bug? How about other “true bugs?”
