Non-member Mark Hinds confirms Hyalophora cecropia from Des Moines, Polk County, with the image below, June 19, 2004.

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.
