Stump Stabber - Megarhyssa macrurus ssp. macrurus
I was so excited to find this giant ichneumonid wasp (Megarhyssa sp.) laying eggs in a snag yesterday. I've only witnessed this process one other time. I watched her for 45 minutes and would have stayed to watch the entire process, but I had to leave to take my son to baseball practice, lol.
Habitat: There were 3 wasps drilling into this snag! Deciduous forest

"Megarhyssa macrurus" is a species of large ichneumon wasp. It is a predatory insect, notable for its extremely long ovipositor. It uses this to deposit an egg into a tunnel in dead wood bored by a similarly large species of horntail. Another of its common names is 'stump stabber' referring to this behaviour.
