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?

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.

Bug of the Week: Sunflower Insect Update

Some of you may remember from the Academy of Science and Technology Blog Carnival 3 post that we are participating in the The Great Sunflower Project.

We got our package of lemon queen sunflowers (Helianthus annuus) in the mail, planted them and were pleasantly surprised when they started to grow like crazy.

This morning I’m happy to report the first bee. No, the flowers haven’t opened yet, but here is a tiny sweat bee resting on a leaf.

It is about the size of a pencil lead. It has been visiting nearby flowers. Can you see the pollen?

A parasitic wasp was also sitting on a sunflower leaf.

Are these insects merely resting in the warm sun?

A clue to what they may be doing comes from the black spots you see on the sides of the photos near the base of the leaves.

ants

Those are ants.

What are the ants doing? Now, many people might think the ants are “eating the plants.” In a way the ants are, but not by chewing on leaves or harming the plant in any way.

It turns out sunflowers have extrafloral nectaries. As I explained in a previous post,  extrafloral nectaries are structures on the plant in places outside of flowers that provide nectar for insects, often ants.

Ants of the Southwest some great photographs of ants sipping nectar from the extrafloral nectaries of a sunflower. Photo 1 and Photo 2. Notice how hairy sunflowers are.

Sometimes bees and wasps may take advantage of the sweet liquid nectar as well.

Just think, insects get their breakfast from a plant and not a flower in sight.
