two sp. of ichneumon ovipositing together
Thanks for your helpful comments and photos of ichneumons. My brother took this picture next to his house in Bloomington MN that might be nice for your collection. We identified the two ichneumons using your page; if I read correctly, it’s a Megarhyssa macrurus and a Megarhyssa atrata laying eggs side by side.
Thank you for sending us your brother’s fabulous photograph. It is one of the best images we have received in a long time. Your identification is correct, with Megarhyssa atrata on the right. Out of curiosity: Does your brother have a name? or, Is he just your brother?
My brother’s name is Jon, and he deserves all the credit! All the best,
