Well, it appears that the caterpillars are doing all right - it is now at least 22 days since they hatched, and we have a second confirmed molt, which is at least their third molt. Two of the caterpillars appear to be bigger than the other four. I really wish I knew exactly when they hatched, but I guess this is just the estimate I have to go with. The recently pinned insects are still on the pinning board - I will probably remove and key the beetle tomorrow, but the grasshopper and katydid will have to wait until they are completely set in place. Wouldn't like their legs to droop. Without further ado, here is the second confirmed molt.
