If you post pictures I can identify them. Tim Thank you Tim. I have identified them already, those showy Saturnids are well known, but as I mentioned my collection is a mess now and i can not post any photos of Eacles. Paul

Exoticimports, thank you for the correction of my statement regarding the species range of Eacles imperialis. After seeing the map I see there are apparent voids in it's distribution. But, then I suppose this could be said of many other Saturniids and Lepidoptera in general. My statement was a general remark which was simply meant to imply that the species as a whole is common over most of it's range. Where it does occur, you will either see the occasional specimen (at some gas station or convenient store) or you will see them in numbers during their cycle. Here in Illinois, I have seen them as occasionals in both Northern and Central Illinois. However, in the lower counties of Southern Illinois where there are extensive hardwood forests the species can be dirt common in July. In 2006 for example a friend and I collected up 70 imperialis on a Friday night and then collected another 65 the very next night. All were picked up in only a 4 hour stretch each night: 9 pm - 1 am. I do not believe there are very many Eastern saturniid species (of such large size) that can be collected in similar numbers anywhere.

I did end up supporting the abdomen the day after I took the picture, so it turned out really nice!

Yes, it is interesting that distribution is inconsistent with no apparent cause. In thinking over this case of imperialis, I initially was inclined to blame century-old clear cutting of NY and northern PA, however the still-virgin Zoar Valley in NY apparently has no record of this species either.
Then again, the BAMONA database is extremely lacking for data. I could triple the number of records from my home county (but it's a PITA because they want a photo of each species and I'm not going to bother myself taking photos of common bugs to prove that I identified them properly.) So it's quite possible that the BAMONA distribution maps are incorrect, yet I can say again I've never seen one in upstate/ western NY.
