From Organ Pipe National Monument comes the small and very common western Lasioglossum microlepoides. Just like the seemingly endless supply of these small Halictid bees, it is slightly metallic and and has a strongly bent basal vein. One could spent a couple lives just figuring out the different species. Photography by Brooke Alexander.

Sara Prado found this Megachile concinna in agriculture fields in her Puerto Rico studies. Is it native to P.R.? Nope. It is a tramp species that shows up in different places from its homeland in the Mediteranean. Photo by Brooke Alexander.

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.

Megachile coquilletti, f, face, Pima Co. Tucson, AZ

A sweet little leaf cutter from Tucson Arizona, Megachile coquilletti is a hole nester and I imagine like its sister taxi in the East probably is happy to nest in people's yards and benefits from rich plantings of desert and dry country native plants. Collected by Tim McMahon and picturated by Elizabeth Garcia.

This is Megachile coquilletti, a small bee from Yolo County in California. "This bee was collected in the California Central Valley in Yolo County for research on small-scale restoration in agricultural areas. Claire Kremen's 10-year study of hedgerows shows the benefits of planting native shrubs and forbs in agricultural areas for native bees.

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.

This species flies in high summer and the female gathers pollen only on the flowers of Vitex agnus-castus.Some alternative or past names for the species include Chalicodoma farinosa or Pseudomegachile farinosa.
