Index of Subjects Hi Dave et al ; from the description(s) both sound very much like cocoons of Saturniids , probably Hyalophora cecropia as JET has suggested in DWs case as the food of choice of cecropia around here Prunus ssp. However H. cecropia being polyphagus Kmac cocoons is probaly cecropia too based on description and not a Sphingid as they are underground pupators and do not spin cocoons. Cecropia larvae tend to be wanderers before spining and the Azalea may have just happened to be a suitable place to spin. If these cocoons are kept indoors under normal conditions then expect diapause to be broken and expect eclosure approx between 18 -23 days . If kept outdoors then expect normal eclosure depending on our spring bewtwwn june 4 - July 1 with peak flight in mid to late June . Hope this helps ! ! !

It was warm to the touch. The cocoon was a sort of elongated triangular shape almost 3.5 inches long (like a big, parchment brazil nut) and the creature within about 2 inches long. I'm guessing it may be one of the large moths like a cecropia or sphingidae. I have kept it safe and hope my damaging the outer covering has not jeopardized the creature. I had, at first, thought it was some kind of azalea gall or spiders nest. Does anyone know when this may "hatch"? Ken MacAulay Port Mouton, NS
