May I ask you another question? I also named BG # 1592946 as Acmaeops proteus. A similar beetle but a different date and plant Was I correct in this identification? or is this longhorn also genus Anastrongalia? There are so many lookalikes out there! Thank you.

This is also an Anastrangalia, but I wanted to resolve the first one before seeing if I can sort this one out. Yes - there are a number of species having this gestalt, and Acmaeops seems to be one of the genera commonly involved in the mixups. The characteristic feature for Acmaeops is the somewhat flattened pronotal disk with the posterior angles developed into broad tubercles - see a good view of this in image # 601912. Gnathacmaeops has the pronotum convex and not flattened, and Anastrangalia has the pronotum cylindrical and narrower apically than basally with the side margins fairly straight.

Thank you so much for looking at this longhorn also. I especially am happy to learn how to tell the differences between these three lookalike genera. Your help is really appreciated.

Thank you so much for correcting my mistaken identification. I look forward to learning about Anastrangalia and the two species you mention. Your help is so appreciated.
