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.

tree cricket female

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?

Meet a Scientist Monday: Mycologists

Do you know what a mycologist does? Let me give you a hint. Think mushrooms, yeast and molds. Yes, a mycologist is a scientist who studies fungi.

Today we are going to visit the Field Museum in Chicago, Illinois and meet two men who are mycologists.

Dr. Greg Mueller was the Curator of Fungi and Chair of the Department of Botany at the Field Museum. He studied the relationships of fungi and trees throughout the world, including Costa Rica and China. Dr. Mueller found that certain fungi increase a tree’s ability to absorb water and nutrients. Understanding how these fungi partner with trees to help them grow allows for the development of more effective reforestation techniques, or conservation practices in the case of undisturbed forests.

How did he become a mycologist? He said he was always interested in nature, and chose mycology after he met an influential professor at college.

Dr. Patrick R. Leacock was a research associate at the Field Museum. He also had an interest in nature as a child. He was introduced to mycology when he joined a mushroom club. Many areas have clubs of people interested in learning more about mushrooms, particularly edible ones. He then went on to get his PhD.

One of his jobs at the Field Museum was to identify mushrooms for the Illinois Poison Center when someone has eaten a mushroom that they shouldn’t have.

Does anyone you know have an interest in fungi?

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.
