Anthidiini
Anthidiini is a tribe of bees in the family Megachilidae comprising at least 40 genera and approximately 840 described species. The tribe is strongly supported as monophyletic based on molecular and morphological evidence. Members exhibit diverse nesting strategies, with many species constructing nests from plant resins, plant fibers, or other collected materials. The tribe includes economically important pollinators as well as cleptoparasitic species in the genus Stelis.
Anthophila
bees
Anthophila is the clade comprising all bees, a monophyletic lineage within the superfamily Apoidea. With over 20,000 described species across seven recognized families, bees represent one of the most ecologically significant groups of insect pollinators. The clade encompasses diverse life histories, from solitary to eusocial species, and exhibits remarkable morphological variation associated with pollen collection and transport. Bees originated from predatory wasp ancestors and evolved specialized adaptations for exploiting floral resources, making them critical components of terrestrial ecosystems and agricultural systems worldwide.
Halictinae
Sweat bees, Furrow bees
The Halictinae represent the largest and most diverse subfamily of Halictidae, comprising over 2,400 species across five tribes: Augochlorini, Thrinchostomini, Caenohalictini, Sphecodini, and Halictini. These small bees are characterized by extraordinary social diversity, ranging from solitary nesting to obligate eusociality, with eusociality having evolved approximately 20-22 million years ago. The subfamily serves as a key model system for studying social evolution due to its recent origins of eusociality and extensive behavioral polymorphisms within and between species.
Nemognathinae
blister beetles
Nemognathinae is a subfamily of blister beetles (Meloidae) characterized by highly modified adult mouthparts, with elongated maxillae adapted for feeding on nectar from deep-corolla flowers. The subfamily contains approximately 8 genera and at least 80-120 described species globally, distributed across all continents except New Zealand, eastern Polynesian Islands, and Antarctica. Members exhibit diverse morphological adaptations including sexually dimorphic antennae in some taxa, abbreviated elytra, and reduced hind wings in certain genera. The subfamily is divided into five tribes: Nemognathini, Horiini, Cissitini, Leptopalpini, and Stenoriini.
