4th and 5th instar. It is interesting having them staggered out like this. When I raised polyphemuses outside they were usually within a day or three of eachother developmentally. Keeping prometheas indoors I have a 2 week spread between the advanced class and the stragglers. Will be interesting to see if the slow ones will get there in the end.

Thank you for continuing to document your previous submissions.  We love seeing the result of the mating Promethea Moths that visited you this spring.
