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.

Yes, we must see more Lasioglossum species in the Dialictus group, just so you start respecting what bee biologists have to deal with. We are subtle subtle people. Lasioglossum sedi here...from Bryce Canyon National Park. Geology is overated when it is bee season in the park. Photography By Brooke Alexander.

From Mount Washington in New Hampshire. A new species for New England this species has a boreal distribution and probably is a hold out from colder days, eking out a living in the White Mountains until global climate change turns it into a jungle.

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.

Here is a little tiny nest parasite, Lasioglossum simplex, that parasitizes one of its sister taxa (likely L. trigeminum). While it retains the overall look and feel of its pollen carrying upright relatives, it has no pollen carrying hairs and its mandibles lack the tooth at the end and instead are simple sabres...

A rather lovely Lasioglossum from Bryce Canyon National Park (L. sisymbrii) als black and white stripes. Common in the West...leaking a bit into the plains, but not much.
