In rough translation this would be the "Florida Masked Bee." Tiny, grain of rice things, and usually mistaken for wasps as they carry their pollen internally rather than in their body hairs like other bees. Thus they have reverted to the wasp shape from whence bees came.

New State Record for Maryland, April 2012 Collected on Willow blooms in Dorchester County....a very rarely collected bee east of the Mississippi. I don't know any recent records

Masked Bee from Dorchester County. An alien masked bee, Hylaeus leptocephalus to be exact. In Maryland (in this case, Cambridge, Maryland) it is almost completely restricted to the urban weedy lot and industrial tract. Railroad lines...the best. Photography by Amanda Robinson.

Colors. You know, bees are so interesting sometimes. Here is Hylaeus pictipes. Jason Gibbs found this species up in Ontario, Canada where it did not belong since it is a bee of the Old World.

A common little bee of the Badlands. Lasioglossum incompletum is at the eastern edge of its range here at the Badlands. No one really realizes that the world is dominated by small bees. So much for bumble bees. Picture by Anders Croft.

One of approximately 1 billions (actually it is nearly 2000) species of Lasioglossum in the world. This one is from Grand Teton National Park in Wyoming. Interestingly, most of these species appear to be generalists so one wonders how they partition their tiny worlds.

Lasioglossum lineatulum is defined in my mind by having relatively few pits on its scutum, a shinyish abdomen, and long straitions on the propodeal triangle. Otherwise it looks similar to the 100 plus other species in the group. This one was captured on Sleeping Bear Dunes National Lakeshore in Michigan.

Here is a little tiny parasitic bee whose host is a little tiny Lasioglossum that is often very common in disturbed / lawn areas (L. imitatum). Note the big head...the long straight pointy jaws and you may have an idea about what they could be used for...but has anyone seen this? No...you should investigate instead of looking at your mobile screen all day.

From Cumberland Island National Seashore another little Lasioglossum from the glossy metallic Dialictus group. As its name implies...it has an unusually long head.

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.

As happens rarely in bees, this bee exhibits both characters of males and females, with bilateral asymmetry. Found by MaLisa Spring in Marietta, Ohio as part of her studies of the bees or the region, which in addition to this species discovered several new state records and rare bees.

One of our native Iris'. This is the Harlequin Blueflag (Iris versicolor), a reasonably widespread inhabitant of mucky freshwater marsh edges. Specimen and photograph from Helen Lowe Metzman.
