Thanks guys. Looking at pictures on Bugguide.net, it does seem to match rasticornis.

Hah, I've made the Corydalus / Chauliodes mixup before. Is the main difference the way the head flares out from the pronotum on Corydalus but not on Chauliodes?

Yes, the pronotum is more slender in Corydalus than it is in Chauliodes. Other useful characters include the presence of white markings in many of the wing cells in Corydalus and the presence of pectinate antennae in Chauliodes (the antennae are never pectinate in Corydalus as far as I'm aware).

Agreed. Coloration of the pronotum is consistent with C. rastricornis.

So when I agree with an identification, the system automatically updates and/or removes my earlier identification? (sorry, I'm new to iNaturalist!)

Yeah, right now you can only have one identification per observation. I've considered making it so old identifications stick around so people can see the full history of the discussion, but haven't gotten around to testing it out.

I think that would be a good idea. Sometimes old identifications are valuable in their own right and it can be useful to see the full history. This is just my opinion of course, but it's how we do things within the scientific community. For example, determination labels are never removed from specimens, even when newer revised labels are added, as the older labels are part of the history of that specimen.
