Explanation of Names
Tetraopes femoratus LeConte 1847
8-19 mm (1)
This is without doubt the most variable and probably the most widespread species in the genus. (2)
Note: edges of mid-pronotal callus are sharply defined (1):

Det. M. A. Quinn, 2016
mostly w US, BC, and Midwest / n Mex. (2), also AL(3)
nearly all BG records from w. of the Mississippi R., similar to the range of one of the primary hosts Asclepias speciosa
mostly: Jun-Sept (BG data)
Asclepias fascicularis, A. hallii, A. lemmonii, A. longifolia var. hirtella, A. meadii, A. speciosa, A. syriaca, A. viridis (2)(4)(5)(6)(7)
Life Cycle
Larvae bore into stems and overwinter in roots. Pupation occurs in spring, and adults emerge in mid to late summer (8)

similar ringed ant. and flattened ant. tip, but has long setae restricted to ant. joints and less well defined mid-pronotal callus (1):
