  • The cosmopolitan bee genus Ceratina, often referred to as small carpenter bees, is the sole lineage of the tribe Ceratinini, and is not closely related to the more familiar carpenter bees. The genus presently contains over 300 species in 23 subgenera. They make nests in dead wood, stems, or pith, and while many are solitary, a number are subsocial, with mothers caring for their larvae, and in a few cases where multiple females are found in a single nest, daughters or sisters may form very small, weakly eusocial colonies (where one bee forages and the other remains in the nest and lays eggs). One species is unique for having both social and asocial populations, , which exhibits all of the pre-adaptations for successful group living. This species is socially polymorphic with both solitary and social nests collected in sympatry. Social colonies in that species consist of two foundresses, one contributing both foraging and reproductive effort and the second which remains at the nest as a passive guard. Cooperative nesting provides no overt reproductive benefits over solitary nesting in this population, although brood survival tends to be greater in social colonies. Maternal longevity, subsociality and bivoltine nesting phenology in this species favour colony formation, while dispersal habits and offspring longevity may inhibit more frequent social nesting in this and other ceratinines. Ceratina are commonly dark, shining, even metallic bees, with fairly sparse body hairs and a weak scopa on the hind tibia. Most species have some yellow markings, most often restricted to the face, but often elsewhere on the body. They are very commonly mistaken for "sweat bees" (family Halictidae), due to their small size, metallic coloration, and some similarity in wing venation; they can be easily separated from halictids by the mouthparts (with a long glossa) and the hindwings (with a tiny jugal lobe). In , a Mediterranean species, males may guard the opening to the nest of a female they hope to mate with, and are often not the father of the brood within the nest; this is the first bee species in which male nest-guarding has been classified as a form of biparental care, but males guarding nests and mating with females has been documented in other species (e.g., Macrotera portalis). A few species of Ceratina are exceptional among bees in that they are parthenogenetic, reproducing without males. (en)
  • Die Keulhornbienen (Ceratina) sind eine Gattung aus der Familie der Apidae innerhalb der Bienen. Die Gattung enthält etwa 350 Arten und ist auf allen Kontinenten (außer der Antarktis) vertreten. In Australien gibt es jedoch nur eine Art. Im deutschsprachigen Raum gibt es fünf, in Deutschland drei Arten. Der deutsche Name weist auf die kurzen, keulenförmigen Fühler hin. (de)
  • El género de abejas Ceratina es cosmopolita, es el único género de la tribu Ceratinini. Son parientes cercanos de los abejorros carpinteros Xylocopa dentro de la familia Apidae. Hacen sus nidos en madera podrida, tallos huecos o agujeros similares. La mayoría son solitarias pero algunas alcanzan un nivel moderado de socialidad (subsociales) donde varias madres cuidan juntas a sus larvas. A veces las hermanas o madres e hijas forman colonias con un bajo nivel de socialidad, donde algunas buscan alimento y otras quedan en el nido cuidando las larvas. Las abejas Ceratina son generalmente oscuras y brillantes con un poco de reflejo metálico, con pelambre relativamente escasa comparada con la de otras abejas y con una canasta para el polen (escopa) más bien rudimentaria en las patas posteriores. La mayoría de las especies tienen marcas blancas o amarillentas en la cara, y a veces también en el cuerpo. A veces se las confunde con las abejas de la familia Halictidae debido a su pequeño tamaño y brillo metálico. Sin embargo, las piezas bucales son muy diferentes. Algunas especies tienen el rasgo poco común de ser partenogenéticas, no necesitan machos.​ (es)
