Rocks Flipped in Sonoran Desert

Because we were eager to participate in International Rock Flipping Day, we peeked under some rocks in our yard this morning.

Flipping rocks was somewhat disappointing at first. It has been the third driest summer on record in central Arizona, and because the summer is when we normally get most of our precipitation, we are really dry. The terms dry as a bone, parched, and desiccated come to mind.  Most of the rocks we looked under would normally have isopods (rolypolies), ants or earwigs, but we didn’t see any of those. Occasionally we might see a scorpion. We didn’t see any of those either.

What we did find was this:

Any ideas what might cause these white tunnels? I’ll give you a hint:  it isn’t a type of spider, although it is made of silk.

In fact, the tunnels are made by an insect. Here are some photos I took of one earlier this summer.

Does anyone remember what it was?

(If you want to find out the answer, check this previous post.)

All in all, we saw something we wouldn’t have otherwise seen, and realized how much the lack of rain is changing the environment for even tiny things that live under rocks. And best of all, we got outside and had some fun.

What did you find?

International Rock Flipping Day

I’m a bit late with this one, but Sunday September 20 is International Rock Flipping Day. Visit Wanderin’ Weeta blog for full details.

Basically you go outside and look under a rock or two. Record what you see by drawing, painting, taking photographs or recording in your nature journal. If you live where there might be poisonous creatures under there, like scorpions or snakes, use gloves and/or a bar to flip the rocks.

When you are done, carefully return the rock to its original position.

If you blog about it, let them know.

Now wasn’t that fun?

Take Time to Hear the Insects Sing

This weekend is a fine time to lay back in a lawn chair, close your eyes and listen to nature. What do you hear? If you are lucky, perhaps you will hear some birds and a few insects. The dull hum of the honey bees flying from flower to flower, flies buzzing or perhaps in the evening, you may hear a cricket or katydid.

Here’s a video of a field cricket singing to get you in the mood (you may or may not want to listen for the entire 2 minutes 🙂 ). Notice the wings moving. The scrapers on the wings produce the chirping sounds in crickets.

Activity 1.

Children love to make homemade musical instruments. To imitate a cricket, find a small comb and a wooden craft stick to represent the file and scraper on the cricket’s wings. Rub the craft stick along the comb. Try fast and slow.

Listen to some of the insect sounds from the links in the next activity. Design musical instruments to replicate them. Have fun!

Activity 2.

If you live in New York City and are looking for something to do on September 11 or if you are simply interested in crickets and katydids, take a look at the event known as Cricket Crawl.

Although the title is cricket crawl, the scientists are interested in 7 insects, including a variety of katydids. The survey itself takes on a modern twist, because the researchers want citizen scientists to actually record the insects with their cellphones and then submit their recordings. The results will be posted real-time on a blog.

The website has a lot of information about singing insects, such how to identify them and links to recordings of their songs. For example, you can find out what the Indian house cricket from last week’s post sounds like at Singing Insects of North America or take a look at (and a listen to) Songs of Insects, for crickets, katydids and cicadas

Here’s a list of Insect Sounds (from Arizona) that include a wider variety of insects, including a cloud of midges and honey bees.

Hope you have a wonderful Labor Day and listen to some peaceful insect music!
