Laphria posticata

This species has been in the literature as being seen in Wisconsin. I believe that it is the more northern of the two species, being found throughout Canada, but does occur into Tennessee and into Georgia.

Identifying characteristics

Like L. divisor this species has the hairs of the mystax, beard, thorax, and the the 4th (sometimes), 5th, and 6th abdominal tergites yellow. The males have black hairs above the eyes, but the female may have some yellow hairs intermingled. The scutellum has black hairs.

Similar species

L. divisor is very similar to this species and it appears to be found throughout southern Wisconsin. L. divisor differs in that it has yellow hairs on the scutellum while this species has black hairs. All specimens that I have collected from central Wisconsin are L. divisor. Photos are not always definitive as the only two photos that I was able to get from northern Wisconsin that may have been this species, the scutellum can’t be seen.

Habitat

Woodlands and woodland edges.
