Eucerini Latreille 1802
see Eucera
212 spp. in 14 genera in our area, ~750 spp. in 36 genera worldwide(3)
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 (4)
clypeus protruding, no stiff hairs beside the margin of the inner eye; top of the head flattish or slightly concave, eyes look bulging (unlike in Exomalopsini)(5)
holarctic and neotropical + ~40 Afrotropical spp. and just a couple in SE Asia(3)
Life Cycle
nests are vertical burrows in flat ground
