When I took a closer look, I found that the plants were being attacked by lots of these caterpillars. Small, black dots (eggs) were laying on leaves, and a webbing enclosed many of the larger groups of caterpillars. I've sprayed with Bt and cut out portions of the lupines that were beyond saving since they were thick with eggs and caterpillars. I've been growing lupines for many years and have never seen these destructive things. Can anyone identify them? What else should I be doing to save my lupines from this infestation? |
