Bug of the Week: Field Crickets

Crickets come in a variety of shapes and sizes.

These husky crickets are called field crickets, genus Gryllus.

Even though they are good-sized, they are still nymphs because they lack wings.

The two projections on the end of the abdomen are called cerci. The cerci look like antennae, and serve some of the same sensing functions. Can you see the hairs on the cerci? Those can detect movement.

Compare these field crickets to slender, delicate tree crickets and the light brown Indian house crickets. Even though they look quite different, you can see crickets all have cerci at the end of the abdomen and have enlarged hind legs for jumping.

What kind of crickets live near you?

Bug of the Week: Cactus Bug

We have had bugs on our barrel cactus almost all summer.

By bugs, I am referring to true bugs called cactus bugs, genus Narnia.

Although they look like leaf-footed bugs, notice the enlarged hind legs with spines and lack of the leafy expansion that gives the leaf-footed bugs their name.

The cactus bug nymphs are bright red. Like the adults, they move slowly away when approached. They tend to hide behind the cactus spines and in the folds of the cactus.

Quiet and cautious, no one really pays much attention to them. Just some simple bugs spending their lives on a cactus.

Bug of the Week: A Different Bee Fly

If someone asked you what kind of insect this is, what would you say?

Because of that long beak (proboscis), it looks a bit like a mosquito, doesn’t it?

Actually it is a bee fly in the genus Geron.

Many bee flies, as their name suggests, resemble small, furry bees. The flies in this group, however, are more slender and they have a “humped” appearance.

The Geron bee flies share a similar lifestyle with the other bee flies. The adults use the long proboscis to drink nectar from flowers, and are considered to be beneficial pollinators. The larvae are parasites of other insects, generally moths.

Seems that in the insect world, as with elsewhere, appearances can be deceiving.
