Adelgids

I'm still looking into these things as I've never heard of them but there's quite a bit on them:

Adelgidae
Gall Adelgids
Hemlock Woolly Adelgid ( Adelges tsugae )
Balsam Woolly Adelgid ( Adelges piceae )

I'm still trying to find a decent picture of a "typical Adelgid" if there's such a thing as the things are apparently so tiny you can hardly see them in a decent picture.

This is interesting indeed. Enjoy educating yourselves. XD
