It seems that Sophia found an Atacus Cecropia out in my chamber last Monday, or the 15th. It soon went to laying eggs on the window-sill, sash, books, etc., of which vide a specimen. Though the window was open (blinds closed), it did not escape. Another was seen at the window outside the house on the south side (mother’s chamber) on the 21st, which S. took in, supposing it the first which had got out, but she found the first still in the chamber. This, too, she says, went right to laying eggs. I am not sure whether this, too, came from the other cocoon. Neither was quite so large as the one I had. The second had broken off the better part of its wings. Their bodies were quite small, perhaps because they were empty of eggs. I let them go. The eggs are large, pretty close together, glued to the wood or paper.
