Bug of the Week: Aphids

Aphids are actually cool insects.

Look at the way the light passes through their antennae and the "tailpipes" on their back ends, which are technically called cornicles.

But most aphids are cool insects in another way, too. They like cool weather. As soon as it gets relatively warm here in Arizona, they are gone.

In fact that one with wings, called an alate, is probably getting ready to go. Can you see the "tube" it uses to suck juices from the flower bud? That's called a proboscis.

When aphids arrive where you live, see what you can discover from looking at them closely. Let us know what you find out.

    Aphids have quite a complex life cycle, but basically the ones that have wings fly or are blown away and the ones left behind are eaten or quit reproducing when it is too hot.
