Laphria divisor

Laphria divisor is very similar to L. posticata. None of the ones that I have collected or photographed have the black hairs on the scutellum which is a characteristic of L. posticata. This species was very common in central Wisconsin in late June of 2008. I saw it in any oak woodland that I visited. It seemed as common throughout the woods as it was on the woodland edges, and often perched near dead logs like the one on which I was able to photograph the female laying eggs.

Identifying characteristics

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 yellow hairs.

Similar species

L. posticata is very similar to this species and it is recorded in the literature as being found in Wisconsin. L. posticata has black hairs on the scutellum while L. divisor has yellow hairs. All specimens that I have collected from central Wisconsin are L. divisor. Photos are not always definitive, but yellowish hairs on the scutellum are obvious on several photos.


Open woodlands and woodland edges.


June through late July


None of the larger Laphria are abundant and seeing more than five of this species would be great day in any one area.
