Aphid defense

The photo shows the abdominal tubes called cornicles which exude a defensive liquid called cornicle wax. It is the orange stuff you can see in the photo. I'm not sure how it works but it is quick-hardening like super glue. Yuck.

I loved your leaf poem on the previous post. The joy of a breezy day.

Awesome close-up, and educational to boot.

I don't know much about aphids, but I'm guessing the wax tastes bad, or smells bad, to a predator? Or maybe it's even toxic?

Great picture! I love insect macros!

Most interesting information. My roses have been aphid free thus far - let's hope it stays that way. Love the macro.
