|A. senatoria female|
As the deck is located on a small bluff over Bull Creek valley with woods and open fields, the variety of moths we attract is quite diverse. Many of the small tan moths are beyond my abilities to identify, while others are distinctive and even beautiful.

|A. senatoria male- Barnhart|
"Females can be twice as large as males. Upperside of female is yellow-orange to yellow-brown; forewing has a white cell spot and varying amounts of scattered black specks. Upperside of male is reddish orange to brownish orange; forewing is narrow with a small white cell spot."
Their larvae are gregarious, clustering on branches while chowing down like a college football training table. They may consume large numbers of leaves on selected trees. This generally doesn't harm the trees as they are eating them during August and September when the trees have already stored up most of their energy for the year.
Chris Barnhart's pictures as usual I found these great pictures of the other three stages of A. senatoria's life cycle. Like many smaller caterpillars, it is really quite beautiful under magnification, a welcome sight unless you happen to be an oak tree.
