Wooly Aphids

Prociphilus tessellatus

Description:

Out for Halloween, are these Wooly Aphids - Prociphilus tessellatus. Also gray insects above the white moving insects. They’re called wooly aphids, and they live off of tree sap. And the white fuzz isn’t actually fuzz, but a waxy substance that the aphids produce as a sort of protection. These are not native, but have immigrated from Japan. They can cause some trouble for your yard from what I understand, because the larvae often congregate on tree branches and do some harm to the trees in such large groups.

Yep - I agree. They're wooly aphids. Here's an info site.

You have a pic of juveniles. The adults are winged insects that look like flocked flies. The smaller insects are also aphids. Sorry, I don't have a specific species for you!

Here's the wikipage on wooly aphids: http://en.wikipedia.org/wiki/Eriosomatin...
