Abelha (Subfamília: Halictinae, Tribo: Augochlorini, Gênero: Megalopta) por Bruno Garcia Via Flickr: As abelhas da família Halictidae são importantes na polinização de numerosas orquídeas brasileiras. Abelhas desta família apresentam brilho metálico verde, azul, avermelhado ou mesmo negro. Possuem diferentes níveis de sociabilidade que vão do solitário ao sub-social. Cada fêmea, individualmente constrói e cuida do seu próprio ninho morrendo antes mesmo de sua cria nascer, ou seja, não há contato entre as gerações. Para esse empilhamento de foco (focus stacking) foram realizados 52 exposições com a lente 18 55mm invertida combinadas posteriormente com o programa Combine ZP.

Maybe Agapostemon, "stamen-lover"

Hey I got a good pic of the culprit from Tuesday! There's a whole group of them. Inat says they're in the subfamily halictinae

Temnosoma, Unknown Metallic Cuckoo Bee, collected in Argentina. A metallic green bee similar to many metallic green bees in the Sweat Bee family Halictiadae, but if you were to look at one under the microscope you would find that the female has no pollen collecting hairs and thus would probably conclude that it is a bee but one that does not collect pollen and therefore it must be a nest parasite and you would be right. These bees lay their eggs in the nests of close relatives. Something else you would notice would be the large number of craters on the surface of this bee’s exoskeleton – these doubtless help trap any sharp sting or mandible tip of a host bee that the cuckoo discovers while attempting to do its darstadly deeds. This group of 7 species occurs from the United States down to Argentina.

A large bright green with blue overtones Agapostemon from Badlands National Park. One of several species present there and very similar to A. virescens and a bit tricky to tell apart. Photo by Wayne Boo with help from Ben Smith on upping the Photoshopping techniques.
