Female came to outside light; laid eggs, eggs hatched July 12, 2001. At first, thought moth was a Saw-Wing (Euchlaena serrata), fed Maple and Apple. When I found out real ID, switched to Carolina Rose (Rosa carolina). Caterpillars were still eating at 91 days old, ran out of food plant after a frost. It appeared that they weren't going to pupate, placed them in cold fruit cellar for the winter. The caterpillars were still clinging to the Rose stem. They stayed that way all winter. When I took them out of the fruit cellar on May 15, 2002, the caterpillars were dead.
