Hoplitis simplex, m, face, Charles Co, MD

A small, hole nesting bee, collected in Charles County Maryland, Hoplitis simplex is uncommonly found and is a specialist on the plant genus Phacelia. Bee specialists such as this little Hoplitis are fundamentally linked to the world's plant biodiversity...not Phacelia...no H. simplex. Photograph by Hannah Sutton.

Hoplitis spoliata, f, back, Kent County MD

A large Hoplitis, that occurs throughout most of North America East of the Rockies. Occurs in low numbers at most locations, in the Mid-Atlantic is is a June bee and associated with what would appear to be mostly Woody blooming plants. Something to consider in your planting pollinator plans... don't forget the blooming shrubs and small trees.

Sometimes male bees depart from the standard antennae shapes for some sort of new performance specs. No body seems to be studying why this might be, but there is substantive research on how incredible antennae can be at detecting just a few molecules.

Aegean islands...have this lovely bee Jelle Devalez (the finder of this bee) writes: "Hoplitis tigrina: one of the largest species of Hoplitis usually found on large purple thistles." And so we must love purple thistles.

Bluets, or Quaker Ladies. Their delicate loveliness does not quite shouw up in these pictures...forming little clumps in poor soils and a part of spring I wait for each year. Specimen and photos from Helen Low Metzman.

Hylaeus floridanus, M, face, Moore Co., N. Carolina

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.

For some reason this species, Hylaeus leptocephalus, one of the masked bees, is one of the first non-native bees ever detected in the Americas. Oddly, it was first detected in the Dakotas around 1900. There must be a good story there, but we don't know what it is.... Reasonably common now, but mostly in disturbed, urban environments.

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 couple more shots of the mysterious female masked bee Hylaeus sparsus. These collected by Jessica Rykken in Shenandoah National Park. Rarely collected by found across hundreds of miles of North America. Makes you wonder what we are missing, my guess is we are missing a lot because no body is actually looking.

A very uncommon masked bee. This is Hylaeus sparsus, which is definitely identified by the spike-like angle on the front coxa (the closest joint to the body). Sadly you cannot see that feature in this picture. More of a spring species than many of the Hylaeus it occurs here and there and appears to be associated with wooded areas.

A rare Masked Bee. This is Hylaues sparsus. It shows up here and there, hard to say where its niche is in the world. No one catches many of them. Can't really pin a habitat on them or a focal plant that they have their favorite pollen.

A native Hawaiian. This species of Hawaiian bee, Hylaeus volatilis, is in the only group of truly native Hawaiian bees, all of which descended from perhaps a single colonization event of a long ago masked bee (Hylaeus) which evolved to become many different species across the island chain, forming partnerships with the native Hawaiian plants.
