Habits

Trigona spinipes builds its nest on trees (or on buildings and other human structures), out of mud, resin, wax, and assorted debris, including dung. Therefore, its honey is not fit for consumption, even though it is reputed to be of good quality by itself, and is used in folk medicine. Colonies may have from 5000 to over 100 000 workers.

T. spinipes will attack in swarms when they feel the nest is threatened. They cannot sting, and their bite is not very effective. Their main weapon against predatory animals (including people) is to get themselves entangled in the victim's hair and buzz loudly. They will also aggressively penetrate human bodily openings such as nasal and auditory orifices when in attack mode.

T. spinipes uses odor trails, sometimes extending to several hundred metres, in order to lead nestmates from the hive to a food source. Moreover, it can "eavesdrop" on the chemical signals used by other bee species (such as carpenter bee

stingless bees) for the same purpose, killing or driving them away and taking over their food source.

The bee has been considered an agricultural pest for some crops, such as passion fruit, because it damages leaves and flowers while collecting nest materials, and tunnels through the unopened flowers to collect the nectar (thus frustrating their normal pollinators). On the other hand, they are significant pollinators on their own, e.g. for onion
