The langorous bright whiteness of the Virginia Fringetree...this specimenk (and photograph) from howard county taken by Helen Lowe Metzman as part of her documentation of native plants. Attractive to bees. Should be planted more often.

Coelioxys sayi, M, Back, MD, Baltimore

The most common Coelioxys in the East. This is C. sayi. Now, C. sayi is a nest parasite (like all Coelioxys) and it likes to drop its eggs in the nest of what is usually the most common Leaf Cutter in the East Megachile mendica.

Colletes aestivalis, m, back, Shenandoah NP, VA

Rare. This bee (Colletes aestivalis) is rarely seen these days. I have never collected one despite it being recorded in Maryland in the far distant past. So it was nice to see this specimen from Shenandoah National Park in Virginia collected by Jessica Rykken in her studies of the Park's bee fauna. Good news.

Colletes brevicornis, f, back, Pr. George's County Maryland

Colletes brevocornis, and uncommonly collected species, one that I associate with dry open areas, it is perhaps a specialist on Venus looking glass in the campanulae family. Difficult to say, since so few have been collected but that is our best guess at this time.

Chino Farms Maryland....they are restoring their grasslands and open land on what I think is the largest farm in Maryland;and as a bonus they got a specimen of the very rare Colletes brevicornis. Hannah and Ashleigh, new interns from my lab took this picture...good job.

Super cool, Super rare, Super fun. Who would say such a thing about a little brown bee? In this case it is Colletes ciliatus. Here is a bee that was featured in a paper we wrote several years ago as one of the "missing bees" not seen for many years.

Colletes Compactus, m, face, Cleveland, OH

Colletes compactus is a late fall Colletes, specializing on things like goldenrod. Colletes is an interesting group....different species coming out throughout the year and many of them highly specialized in what they gather pollen from. They perhaps are all specialists, but some are quite rare and so we know little (a common story).

Dasypoda plumipes, Hairy-footed Hairy-legged Bee, collected in the United Kingdom.The common name of this species is an accurate description of the bushy pollen carrying hind legs of the female (male bees do not transport pollen back to a nest).
