What’s this bug
I spotted this bug soon after I cut a limb of a large maple tree. I’ve never seen anything like it before. What is it? Thanks,
This is a female Giant Ichneumon, Megarhyssa atrata. She is ovipositing or laying eggs. She locates the tunnel of a wood boring insect and lays the egg where her larva can find the wood boring grub and begin to feed on it. Your photos are excellent. The portrait is a nice angle.
