Washington, Mar 24 (ANI): Social bee
queens- like those in the tropical sweat bee species, Megalopta genalis in Panama-have bigger brain region responsible for learning and memory than in solitary queens, according to scientists.
In context-dependent social interactions, it has been recognized that an individual female of a solitary bee species is able to recognize conspecifics and modify her behavior in accordance (Wcislo 1997); similar capacities are known from solitary wasp studies (Pfennig & Reeve 1989), and from individuals of social bee
species (Michener and Smith 1987).

The study is the first systematic test of job skills in a social bee
or wasp, says Raghavendra Gadagkar of the Indian Institute of Science in Bangalore.
In addition, among their 200 species the euglossines do not include a single advanced social bee
, in contrast to the other corbiculate Apinae - the honey bees, bumblebees, and stingless bees - all of which form colonies with a queen, workers, and stored honey and pollen (Roubik 1989).
With the antennae, the social bees
tended to have a greater density of sensilla, the tiny hairs on their antennae that do the heavy lifting in communicating with others.
