More leafcutters from Pictured Rocks National Lakeshore. In this one the big mandibled Megachile melanophaea. If it is like its kin, it likes thins in the pea family, but as usual, the basics of how it exists on the planet are only sketchily known. Why don't you do something about that viewer? Photography by Colby Francouer, shopping by Elizabeth Garcia.

Here is a bee from Acadia National Park in Hancock County Maine. The park is one of the few places that has information about its historic bee populations., Resulting in one of the very very few instances of a historic record of any kind of bee populations in North America. An Illustration of How Poorly Known the bee fauna of the continent is currently.

Megachile mendica is a very common bee, but in this case it is founded on a very rare plant, Ruth's Golden Aster. Collected and photographed by Philip Moore as part of a survey of that plant species and its pollinators from Polk County Tennessee.

The male of Megachile mucida, this is one of the leafcutter bees, here even the male has a massive mandible, though it does not involve itself in making or tending nests....note the forelegs which are tucked under the front of the bee, these are widened greatly and are used to cover the eyes of the female when mating.
