Explanation of Names
see Eucera
212 spp. in 14 genera in our area, ~750 spp. in 36 genera worldwide(1)
Hairy bees, typically with pale hair bands on the metasoma. Males typically have very long antennae. According to the site linked below, "two distinguishing characteristics are the following: the Eucerini have long paraglossae [lobes at the outer edges of the tip of the lower mouthparts] that reach the base of the labial palpus. They also have parocular carina [ridges on the outside portion of the eye area].
Key to genera in LaBerge (1957)

The clypeus protrudes notably. (2)

No stiff hairs beside the margin of the inner eye, distinguishing them from Exomalopsini. (2)

The top of the head is flattish or slightly concave, distinguishing them from Emphorini. This gives them an appearance of bulging eyes. (2)

shows the inner eye and top of head well.
holarctic and neotropical + ~40 Afrotropical spp. and just a couple in SE Asia(1)
Life Cycle
Nesting is in the ground for all species. Known nests are vertical burrows in flat ground.
