Copyright
I am creating a dichotomous key to the Nearctic species of Megarhyssa with some friends, and we were wondering if you'd allow us to us this image as an example in the key. You licensed it under No Derivs, so we won't be able to crop or add arrows over the image in order to make the features more visible. You can see examples of my work on keys at https://sites.google.com/view/flyguide/eristalini.
Best,
Zachary

Thanks for posting this sight
Thanks for posting this sighting to BugGuide! I hope you enjoy using the key to the species of Megarhyssa in the Nearctic region that I co-created with your photo. You can find the key

Subspecies designations should not be used since, as noted, they were synonymized under Carlson (1979) and are retained as synonyms by Pook et al. (2016). Intermediates also don't quite fit under either designation, even if this is closer to one than the other.

Megarhyssa
Hello Ross, I've been working on a visual key to the 4 species of Megarhyssa north of Mexico (Specifically aimed at identifying photos posted in citizen science websites) with a friend, and we are perplexed at this individual. Not only it lacks the typical "v-shaped" bands on the metasoma, but the wings are also very obscured, which seems to be rather rare on M. greenei. I might be wrong but at least from the second picture I would count two dark patches on the wings? based on ovipositor length greenei should be correct but it sure is odd.
Could this be a teneral individual?
Thanks.

Near "floridana" coloration
The dark wingscand reduced yellow markings are close to the former subspecies
M. greenei floridana
. It's only known from Florida. Carlson synonymized the subspecies as the extent of intermediates defies the taxonomic concept of subspecies, with intermediates known at least in South Carolina. This is within about the same radius, so it's most likely that there's a whole intermediate zone (and thus validating Carlson's synonymization).
