Hylaeus sparsus, f, left side, Shenandoah, VA

Collected in Shenandoah National Park

Nomada graenicheri, f, right, Buckingham Co., VA

Now here is a beauty. Nomada graenicheri, rare as all get out and its host is unknown (but could be one of the summer Andrena...). This one was collected in the mountains of Virginia by Megan Ayers as part of her team's efforts to survey the bees of that state. For some reason the facial shot presents notes of anime...at least to me. Photo by Erick Hernandez.
