Megarhyssa macrurus lunator

This is one of the more impressive parasitoids found in North America: Megarhyssa macrurus lunator, a parasitoid that attacks sawfly larvae.  My son Eitan discovered this one on a hike to Castle Rock in the Adirondack Mountains of New York.  Notice the impressive ovipositor, arching up over the wasp’s back, and then down between its legs, where it is drilling into the log in search of its host.
