Non-member Mark Hinds confirms Hyalophora cecropia from Des Moines, Polk County, with the image below, June 19, 2004.
Mark also sent me an image of an Eacles imperialis larva in September, 2003.
Non-member Julie Alvarez, Linn County, confirms Actias luna with a larva find on September 29, 2002. Larva turned amber just before spinning.
Non-member Cindy Wardle, Burlington, Iowa, (Des Moines County) writes, "I'm so excited. I was mowing the other day and this beauty caught my eye. Had never seen one before and took a lot of pictures and video.
"I believe this was a female. The body was huge! It stayed from the time I saw it until it flew away for about 10 to 15 minutes on the side of a wooden outdoor figure we have. It keep "humping" its body up and down on the side of this wood figure.
Then after it flew away there was a small line of liquid running down the side of the wood."
Cindy sent me images of Hyalophora cecropia
and I suggested the cocoon to be nearby as the "squirt" was probably
metabloic fluid, generally expelled at first flight.

Thomas has been updating me with regard to Sphingidae and Saturniidae images and sightings from Iowa each year since 2010, and I have been adjusting the Iowa range maps (Saturniidae) and county thumbnail checklists (Sphingidae).
I don't think I have ever seen the dark grey to black pm line, evidenced in the image below, on lunas from New Jersey to PEI, Canada.
