Tetraopes - Milkweed Longhorn - Tetraopes femoratus
Golden Ponds, Longmont, Boulder County, Colorado, USA
June 25, 2016
On A speciosa. I would generally assume T femoratus, but the basal segments of antennae is black, there is almost no orange on femora, and the pronotal ridges seem weak/ill defined. But then again, I can't find a better match on the pages in BugGuide

Moved for expert review to Tetraopes
T. annulatus comes to mind, but I am not a specialist in this group
