Dasher - Micrathyria - BugGuide.Net

Thornbush

I know this is late and I don't know if anyone will see this, but this is definitely M. hagenii. The pale area just before the black fork in the interpleural region reaches the top of the thorax, which would not happen in spot-tailed. Thorax pattern eliminated didyma and abdomen pattern eliminates dissocians.

Possibly - Micrathyria sp.

Why couldn't this be a female Micrathyria sp.?
The third thoracic stripe (interpleural) looks forked at the top to me.

I could have been a little ha

I could have been a little hasty with the ID, but typically Micrathyria hagenii (I don't think it is Micrathyria didyma from the thorax pattern, but it might be female M. aequalis) females have a larger pale spot on S7 that meets at the top of the abdomen, a sort of "taillight" effect. From this slightly below angle that is not real visible. There are also differences at the front of the wing on the thorax, but again, not visible from this below angle. I'll move it to libellulidae and see if someone else has some ideas. I think you are right Bill...Micrathyria aequalis female may be a good bet. Not sure I can tell for sure from this angle though.

Greg, I've posted a cropped version. I hope this helps, even with the bad angle.

Thanks Bryan. I think Bill is

Thanks Bryan. I think Bill is correct and it is a Micrathyria, but I'm not sure I can call it to species level. Females can be a challenge from a photo. I'll see if I can get a few other folks to have a look.

I asked Dr. John Abbott to look at this. He agreed with Bill that it is Micrathyria. He did not think it was aequalis so he leaned toward hagenii (Thornbush Dasher). Hard to be certain on a female from this angle.

Please let me know if I need to crop/magnify a certain area. I appreciate all the effort.
