Augochlora
green sweat bees
Augochlora is a genus of small, metallic sweat bees in the family Halictidae, comprising approximately 127 valid species distributed from southern Canada to Argentina. The genus exhibits remarkable social flexibility, with most species showing facultative eusociality while at least one species, Augochlora pura, is exclusively solitary. Members nest primarily in decaying wood, though some species utilize soil. The genus is divided into three subgenera: Augochlora s. str., Oxystoglossella (formerly Oxystoglossa), and the extinct Electraugochlora known from Miocene Dominican amber.
Xylocopinae
Carpenter Bees
Xylocopinae is a subfamily of Apidae comprising four tribes: Xylocopini (large carpenter bees), Ceratinini (small carpenter bees), Allodapini (allodapine bees), and Manueliini (genus Manuelia). It represents the most basal lineage within Apidae and exhibits remarkable diversity in social organization, ranging from solitary to primitively eusocial and obligate eusocial with morphological castes. Most species nest in dead wood, hollow stems, or pith, though some lineages nest in soil. The subfamily has a worldwide distribution except Antarctica, with highest diversity in tropical and subtropical regions.
