We just spotted this large bug on our window screen. Is it a type of ichneumon wasp?

Dear Jessica,
This seems very late in the season for a Giant Ichneumon sighting in Pennsylvania, but this is nonetheless a Giant Ichneumon in the genus
Megarhyssa, most likely Megarhyssa macrurus.

Thank you so much for the quick response. It has been unusually warm so maybe that explains it. Can’t wait to tell the kids more about this bug. We get a lot of types at our house.
