Julia Wayg sent me a great description of a mature Eacle imperialis larva she encountered August 23, 2010, in Frederick County, Maryland.
it was crossing the road;
it is: 4-5 inches long;
about as round as a nickle
Very deep green (forest green)
as some fine hairs.
has rows of small yellow dots along its body;
has horns at both front and back that are yellow;
feet are yellow
its back end has yellow markings that I think kind of look look an owls face.

Mike Soukup writes, May 18, 2004, "Just a note to let everyone know I am experiencing a massive amount of Poly's here in Anne Arundel Co., MD. I had an inaccesible female calling the other night. Normally, this would result in 10-15 male poly's at my lights. I was able to find and count 113 of them all around my house - at lights, on all of the trees, bushes and shrubs.

Regalis, Imps, A. senatoria, A. stigma, A. virginiensis, D. rubicunda, A. io, A. polyphemus, A. luna, C. promethea, C. angulifera, H. cecropia.

"I also, on occasion, get C. sepulcralis.... but I normally go to So. MD to get them (and I should go this week since they are hatching).

"It has been a great year for Sats. There are about 45 polys just sitting around the house now,. My calling promies have been attracting 50-60 every evening. And. the T-Trees have been attracting 10-15 males (from what I can see by Flashlite). io's and senatoria and regalis just eclosing....."
