Impatiens capensis 2, Jewelweed, Howard County, MD, Helen Lowe Metzman

Impatiens capensis, Common or spotted Jewelweed. A lover of wet spots, its vegetation is viscous, wet, and used as a wash when you may have been contacted by Poison Ivy. The flowers are total bumble bee bait ...just the right size and the spur at the back end is full of nectar. The orange color is also highly attractive to hummingbirds as a bonus.

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.

Lasioglossum lineatulum, female, left side

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.

Lasioglossum microlepoides, F, Back, AZ, Pima County

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.
