This is one of the plants that they are feasting on.

few raspberry plants= smash the critters

If a moth or butterfly BT will work, If something else spinosad will probably work. Both organic. Any of the powerful synthetics can be used too. Like Sevin, malathion, acetamiprid or pyrethrum can be used.

The pest is probably a species of leaf roller catapillar.
Both organics work on the larvae. But not the eggs. Oil or soap may help?

Moth caterpillar for sure, I don't see any rolled leaves, this cat could be one of the "skeletonizers" that leave just the leaf veins.

Many of the above control methods are worth a try. Some labels may include moth larva in the control listing.

I think all of them do! I know the organics do. And the others kill everything.

thanks, I'll spray tonight.

Boy oh boy....that looks like the dreaded raspberry sawfly to me. My Anne's were devastated this year, Heritage less so. I lost a lot of time and crop using BT because I saw what looked like caterpillars of some sort (moth larvae). Sadder but wiser, I strongly recommend Spinosad and maybe something stronger after you've cut the plants back. BT is useless against the sawfly larvae (which are actually wasp larvae). Spinosad, used diligently, can help.

If a sawfly, the larva will have legs on almost all body segments, a moth caterpillar will only have a few legs up front and one pair in the rear. Sawfly larva are somewhat hairy and are generally present in the spring whereas moth cats can do damage well into the fall.

EarthenDelight, Am I wrongly assuming that you are a spammer?

No idea what that comment meant, other than getting me to view your website.
