"This is Gymnetis flavomarginata Blanchard. It is native to the SW U.S. and Mexico. It has been in central Florida for several years, so it apparently is established. I received another specimen back in late May from Quietwater Cove, Altamonte Springs, FL 32701. I see from a web search that G. caseyi looks the same, I'll have to talk to a beetle expert about that. But he has told me that the one we have in FL is G. flavomarginata." Lyle Buss

Thank you everyone for all th
Thank you everyone for all the hard work!!!!!

caseyi & flavomarginata are synonyms
see comments here and here

I'm to blame
for the incorrect name. Although I have my doubts as to just how distinct caseyi is from flavomarginata, caseyi is currently the correct name for the Texas population. However, the Florida population is clearly adventive and I don't know if it originated in Texas or further south.

good point
I assumed this came your way from Texas, but ... maybe not. The Florida ones can always be moved if you decide its something else, like the "real" flavomarginata from further south. I guess I shouldn't have said that caseyi and flavomarginata are syn., not really true.

I found and still have this s
I found and still have this species in Altamonte Springs, Florida. It's really taken to oranges... If there is anything I can do (picture wise) to further help w/ the ID please let me know.

I believe Mike has
at least one and he'll figure it out. A bug in the hand is worth two images from the bush.

Gymnetis caseyi Antoine
I compared Florida and Texas specimens externally and internally and looked at Antoine's paper, and the Florida population is G. caseyi. Gymnetis caseyi is a replacement name for Gymnetis sallei Casey 1915, which is a junior homonym of G. sallei Schaum 1844. Antoine treats G. sallei Schaum as a subspecies of G. chevrolat Gory and Percheron. Gymnetis flavomarginata is from Argentina.

thanks Phillip
I've fixed it.
