Ceratina dupla
doubled ceratina
Ceratina dupla is a small carpenter bee in the family Apidae. It occurs in the eastern half of North America and parts of Central America. The species was formerly confused with Ceratina floridana and Ceratina mikmaqi until molecular analyses revealed significant genetic differences. It is a solitary bee that nests in the pith of dead twigs and has been documented visiting multiple flower species in prairie habitats.
Hoplandriini
Hoplandriini rove beetles
Hoplandriini is a tribe of small rove beetles (Staphylinidae: Aleocharinae) containing at least 5 genera and 21 described species. The tribe includes the genus Microlia, whose members are pollen-feeders frequently associated with flowers of Cucurbitaceae, Solanaceae, Asteraceae, and Monimiaceae. Some species, such as Microlia cayaponia, have been observed foraging on Cayaponia flowers and may compete with pollinators for pollen resources. The tribe occurs in the New World and Australasia.
