Aptly named: Lasioglossum coeruleum. Most of the many confusing members of these small sweat bees glimmer discretely in metallic integument, but our friend here takes it up a notch to and Osmia level.

Such a lovely blue and relatively unusual in the Genus Lasioglossum. At least in the East there is no other Lasioglossum so extensively and uniformly blue. So blue that it is often mistaken for an Osmia. This species is associated with woodlands, feeding on the vernal flora of the woods and nearby fields and nesting in rotten wood.

One of the most common and plain bees in the East. This is the very small Lasioglossum hitchensi. Its commoness did not prevent it from being undescribed scientifically. In only the last 10 years was it given a name by Jason Gibbs, who extracted it from many confusing and similar look alike species.

Male Lasioglossum can be tricky. Here is one of the dark ones from the highly bee productive Fossil Butte National Monument.

One of what seem like one billion different kinds of small shiny slightly metallic Lasioglossum species. This one characterized by very sparse pitting on the top of the thorax and bit more glintyness on the abdomen (yep, not great characters).

Now, this is an interesting bee. Obviously it has occurred in Michigan, and indeed until quite recently that was the only place it was known from and in fact, was known only from one single specimen. However, it was so unique that was described by Ted Mitchell over 50 years ago as a new species.

Wetland Bee. There are many bees in wetlands. Why? Because so many wetland plants have flowers that are designed to lure bees. Why, for example, are water lilies so large and colorful? So they look good in our pretend ponds? Nope. To attract bees out into the pond for a little pollination fun? Yup.

A little parasitic Lasioglossum from Frederick County, Maryland. The female invades nests of other Lasioglossum species and lays her egg in their nest. The host egg/baby does not fair well after that. The most common of the parasitic Lasioglossum species.

Bryce Canyon, little tiny sweat bees, lots of different species. Not what people come to see, but what you now can see here because the National Park Service cares. Photography by Brooke Alexander.

Rare. This small little Lasioglossum sequoiae is all black. This particular specimen was collected in the San Juan Islands of Washington in the National Historic Park and identified by the fabulous Jason Gibbs. This represents a major range extension for all the previous specimens we are aware of are known from California.

We have had pictures of this sand lover before, but just got this one fresh from a study of a local sand mine where with the state mines division they created new bee habitat as a trial and this sand specialist was glad to show up.

From Bryce Canyon National Park comes a small Lasioglossum, similar to many other species of this specious genus. Western in distribution I know actually nothing about its life. Picture by Brooke Alexander.

From one of the coastal National Parks in St. John's County in Florida comes a lovely red-legged Lasioglossum tarponense. I think of this species as a sand specialist...living in the Florida scrubby sand coastal pine matrix that forms an important part of the natural matrix of the region behind the sand dunes.
