Found on screen door about 7:15 a.m. July 9th in Gaines, Pennsylvania. He is about 2 1/2 to 3 inches long. Long narrow neck and head with what looks like pinchers a the top of his head. First thought he was a praying mantus but he does not have the correct stance. Can you identify him?
Your insect is a female dobsonfly.
The females do not have the long ‘pinchers’ that the males do, but can bite or pinch more effectively than the males.
These insects are found near fast flowing streams so there must be one nearby. The adults come to lights at night. Adults do not feed.
Larvae are aquatic predators, living in streams. Two-three years are spent in larval stage, at end of this time larvae crawl out of stream and form a pupal cell under a log, rock, etc. and then overwinter. Adults emerge spring to summer.
These are found thru out the eastern half of North America.
