Megachile concinna, M, Side, Puerto Rico, Boqueron

Here is a small leaf cutter from Puerto Rico. However, it is not native to P.R. but likely inadvertently introduced through its habit of nesting in holes in wood...which could be holes in pallets or packing crates. Found is scattered locations around North America and even in Hawaii.

One of the resin collecting bees, they are in the leaf-cutting bee genus, but separate their walls with resin rather than leaves. They love it if you drill holes in your porch posts (personal observation). This Megachile exilis males has some expanded front leg segments that help in its id...how nice. Collected in Talbot County, Maryland.

There are many Megachile in the world here is one captured in western Maryland and photographed by Heagan Ahmed. Photoshopping by Elizabeth Gardia. For some reason the species seems to be showing up more and more in Eastern North American collections.

Leafcutting bees are normally bright white sorts of things in North America...hoewever, there are a few such as this Megachile gemula that are dark, not in a psychological way, but in that their pollen carrying hairs are black instead of white and much their pale hairs bleed from off-white to yellowish.

A common and large leafcutting bee from Maine, collected by Brianne Du Clos. This is a male and note the large expanded tarsal segments on the front legs. These are used to hide the females eyes during mating. Dejen Mengis is the photographer.

A sharp looking Megachile from Yosemite National Park. Megachile melanophaea is a bee that runs all across the arctic, the northern parts of the East and down the mountains in the West. Unlike many northern species is does not seem to be interested in the Appalachians.

Leaf-cutter. The most common leaf-cutter in most of Eastern North America. It carries pollen on the underside of its abdomen and those hairs are distinctly tinged with orange, something found in only a few other eastern Megachile. Photograph by Amanda Robinson.

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.
