University of Alberta E.H. Strickland Entomological Museum

SeasonalityU.S. material (mostly from Texas) shows adults being collected from June to August. One Alberta specimen was collected in July. IdentificationAdults: 9.7-12.1mm in length. Known to have four color phases throughout its range: A green phase, with metallic green head, pronotom, and elytra; a blue phase, with dorsal surface blue; a weakly bicolored phase, with head and pronotum metallic green and elytra blue-green and a strongly bicolored phase which has a metallic green head and pronotum and elytra that are dark blue, violet, or blue-black. Alberta specimens are mostly green phase but occasionally of the weakly bicolored variety. Elytral epipleurae are entirely black and the ventral surface of this species is also entirely black. Appendages are entirely brown-orange and antennal segments 1-3 are slightly lighter than segments 4-11. Labrum truncate to slightly emarginate; pronotom transverse, widest at middle; lateral margin not sinuate. Elytral disc slightly convex; striae moderately fine, with fine, close punctation; intervals are flat and densely punctate. Micro sculpture is granular and fairly prominent. Adapted from Bell 1960.
