Fort Mantanzas National Monument has Megachile pseudobrevis living in it. How nice that National Monuments now become sanctuaries for bees and Nature while we continue to tame to death the rest of the world. Photography by Miss Sierra Williams.

A large hole nesting leaf cutter. This is a male Megachile pugnata (subspecies pomona) from Yosemite. Check out the greatly expanded pale segments of the front legs. These are used in mating and lain over the females eyes. People make up all sorts of stories with that information, but we really don't know that details about why that is a useful feature.

The magnificent mandibled Megachile pugnata. Look how long and wide those mandibles are. Its not clear to me why this species requires much longer mandibles than others, it appears to not be cutting out larger pieces of leaves for its nests, but perhaps it is the type, processing and location of the leaf material that is important.

Some rather bad pictures of M. pugnata males. Not sure why I selected this specimen. Terrible hair. But, anyway check out the large expanded front tarsi. Will have to get additional specimens. Collected in WV by Dave Smith who had fabulous numbers of specimens in malaise samples. Still going through them after 10 years.

Megachile relativa, 420668, Garett co, Back

Megachile relativa, a relativa (get it?) common species in northern parts of North America. The orangish pollen carrying hairs under the abdomen are uncommon and therefore useful when sussing out this species.

Megachile relativa. Pretty ubiquitous in North America though it appears to be absent from most of the Midwest. The orange pollen carrying hairs on the underside of the abdomen narrow things down in terms of the various Megachile species, bug there are a few species that look very similar....particularly the introduced Megachile centuncularis.

A purposefully introduced bee, used, at times, in the pollination of alfalfa and other crops, but now widely naturalized and can be found throughout North America, particularly in urban or disturbed areas. Collected by Tim McMahon in Cecil County Maryland and photographed by Brooke Alexander
