I think mistaken identity happens a lot. I have seen mixed pairs of
Aeshna darners on frequent occasions. I have the impression if a male
Aeshna sees a female Aeshna, he will try to mate with her, no matter
what the species. I don't have any data on Anax making similar
attempts, and perhaps it's less likely, as Anax and Aeshna are rather
I don't know if this would shed light, but I have a photo of a female
Anax junius eating a male Aeshna constricta in Nebraska. I think the
male was still immature, perhaps explaining why it could be caught by
the Anax. It was quite a sight.
