Some species, nevertheless, are more suitable for rearing at home as pets. The "mandaçaia" are extremely tame, not attacking humans even when their hives are opened for honey extraction or colony division. They form small, manageable colonies of only 400–600 individuals. At the same time, a single rational beehive of "mandaçaia" can produce up to 4 liters (1 US gallon) of honey a year, making the species very attractive for home keepers. They are fairly large bees, up to 11 mm (7/16") in length, and as a result have better body heat control, allowing them to live in regions where temperatures can drop a little lower than 0 °C (32 °F). However, they are somewhat selective about which flowers they will visit, preferring the flora that occurs in their natural environment. They are thus difficult to keep outside their region of origin, along the east coast of Brazil from the state of Bahia south.
