Another species of giant ichneumon, sharing the same stump with Megarhyssa atrata. A dozen of these were searching the wood beetle holes on the stump, and laying eggs.

Nice one. There are only a handful of species in this genus, and I think only this and M. greenei have yellow chevrons on the side of the abdomen. M. greenei should not have that dusky patch in the wings (I think), so I believe this is M. macrurus.

Nice, thanks. I love the Megarhyssas, they're amazing to watch.

Wikipedia says they oviposit starting June. It is interesting that you observed an early one. I also observed an individual ovipositing: https://vimeo.com/71611503
