I brought inside a milkweed leaf with an egg on it and put him in a plastic cup.After hatching, instead of eating
like he was supposed to , I found him, standing on his hind legs with his body extended straight out ,
from the side of the cup.I coaxed him back on to the leaf,closed the cup, checked a few hours later, and he was on the plastic again. Also,I noticed he used the "inchworm" method of walking. He later died. I had checked the egg when I brought it in-it looked like a classic monarch egg to me.What accounted for this behavior?-Was it anything that I did?
