My caterpillars are not moving. Are they dead?

Question: My caterpillars are not moving. Are they dead?

Probably not. Caterpillars often rest for hours at a time, especially just before molting. To see if a caterpillar is alive, open the cup and gently touch the caterpillar with the tip of a soft brush. This should cause the caterpillar to move, if only slightly.
