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.
