I had my Red Admiral caterpillars outside on the back patio, on their stinging nettle cuttings, the stems of which were immersed "boquet style" in a container of water. An earwig found his way onto the plant and attacked both caterpillars. He was still at the scene of the crime whem I was checking on the caterpillars this morning. One of them had already started to pupate. Dang.
