Hemlock Wooly Adelgid

I thought - super cool insect discovery!  Weird weird!  These little grey lumps - clearly insects, that shrink away from being poked, all grouped up on a branch, with abundant hairy frosting all over them with a kind of fungus texture.Different!  Never seen anything like it.That's because it's a dire invasive species recently arrived in Nova Scotia and destroying hemlock stands.Just great.  Another invasive species.This little clump was about 8' from our door, and also, it was on a small alder.  If it's happy on alder, then it will have no shortage of hosts.
