Observation of Trigona recursa Smith (Hymenoptera: Apidae) Feeding on Crotalaria micans Link (Fabaceae: Faboideae) in a Brazilian Savanna Fragment

In this paper we present observations of individuals of the bee species Trigona recursa feeding on the fruits of Crotalaria micans. This plant, which contains pyrrolizidine alkaloids, is known to be toxic to humans, mammals and poultry. Over the cou...
