Bug of the Week: Summer Sounds 2

Although we expect to hear cicadas this time of year, there’s a new sound at night in our yard that we didn’t predict. Follow this link to hear what it sounds like:

Any idea what it might be?

These photos might be a clue.

This individual is a female, which because of her long egg-laying tube or ovipositor. She isn’t the singer, however, only the males sing.

This is a female tree cricket (genus Oecanthus). A tree cricket is more slender and delicate than the common field cricket. One type of tree cricket, the snowy tree cricket, is used as a thermometer because the frequency of its chirps can be used to calculate the temperature. The snowy tree cricket has a similar appearance to this one, but it is pale green or almost white.

Based on the tan coloration, this is probably the western tree cricket. Although we’ve seen and heard tree crickets in other parts of Arizona before, this is the first time we’ve had them in our yard.

The tree cricket males sing in a different way than cicadas. Instead of vibrating tymbals, the male tree crickets rub ridges on their wings together. Check Grasshoppers & Allies Supplemental: Tree Crickets (Oecanthus) for photos of male western tree crickets using their wings to chirp.

So, what animals are you hearing in your area right now?

If you child is interested in crickets, try reading some of these:

Summer Sounds 1

Any idea what this alien-looking creature is?

cicada

Cicadas are large insects with bulging eyes. This one is whitish because it has a fungal disease.

Father’s Day marks the beginning of the cicada season here in the Sonoran Desert. The emergence of these noisy insects predicts the beginning of a change in the weather, with higher humidity and the onset of the violent rains called monsoons. Unlike the spectacular periodical cicadas, our cicadas emerge every year. They sing on and off for a month or so.

Ever wondered how the cicadas produce their loud buzz? On the sides of the male cicadas (although some females have them, too) are two thin areas called tymbals. When muscles inside pull on the tymbals, they collapse causing a click. When the muscles release, the tymbal clicks again as it snaps back.

The video of the tymbal moving in slow motion at Discovery Channel’s Time Warp: Cicada Sounds is very cool.  The tymbal is the white area that is moving in and out. Too bad there isn’t any sound to go with it.  Note: the short advertisement at the beginning of this video may not be appropriate for young children.

According to the schedule, the entire Time Warp episode with the cicada footage (it is called Stuntmen) is being aired on the Discovery Channel on Monday June 21 at 9:00 am. It is rated TV-PG. It might be a fun way to start summer.

Bug of the Week: Fireflies

Our family just got back from an awesome trip to Upstate New York and Pennsylvania, where we got to see many incredible insects. Our favorite is the Pennsylvania state insect, the firefly.

Fireflies or lightning bugs are actually beetles.

There are many different species of fireflies.  This is a common one in upstate New York. Others may be brown, or brown with red markings. The fireflies in Arizona don’t flash, but are similar in appearance to this one.

I had always wanted to take a picture of fireflies flashing at night. This time I was able to take some long exposure photos (thus the blurriness) of fireflies in flight. See if you can spot them.

I can’t wait until next year. I’m going to try it with a tripod in a better spot.

Do you have any photographs of fireflies? We’d love to see them.

For more information, see:
Absolutely stunning photographs of firefly beetles at Firefly Forest

In a previous post, I answered some questions about fireflies, including what they eat.

Most of you probably already know about the Firefly Watch project, first brought to our attention by DNLee at Urban Science Adventures.
