what's this black caterpillar in white lacey web on echinops?
We hand picked them and destroyed them but someone on the New England gardening forum suggested they might be butterfly caterpillars.
I've never seen them before. The echinops is 12 years old and this year the bulbs (flowers) are being attacked by this critter, so the stems are bent over as if broken right under the bulb.
Anyone know what it might be?
