Overview of our fauna (* –taxa not yet in the guide)

Halictidaes are distinguished by the arcuate (curved) basal wing vein as shown here
. All Halictids have short tongues and only one subantennal suture. (4)
OVERVIEW OF GENERA
Genus Agapostemon - Metallic Green Bees
Typically ground-nesters, with nests formed in clay soil, sandy banks of streams, etc. Most species are polylectic (collecting pollen from a variety of unrelated plants).
A few species are attracted to sweat, and will sometimes sting if disturbed, though the sting is not very painful (2)
. Some are parasitic, especially Sphecodes
Some metallic-green halictids superficially resemble cuckoo wasps (Chrysididae)
, but lack the sculptured cuticle and the ability to curl up in a protective ball.
Similar looking metalic green bees with the basal vein often slightly curved.
