Some of my nymphs have died for no obvious reason. i saw one on his back but still slowly moving, so i figured maybe he was hungry. i put him on an orange slice and he ate like no tomorrow. maybe some have died of dehydration because they don't eat? I put an entire buffet out for them, but maybe they're just kinda dumb? I've got orange, green bean, pea, carrot, lima bean, corn, and pecan pieces in there. :? Any ideas?
