Resumo
The aim of this study was to analyze the distribution pattern of the food collected among groups of individuals in Mischocyttarus drewseni colonies. This behavior is one of the first actions exhibited by the foragers when they arrive in the colonies. Regarding nectar and prey collection, 95.90% of the collected nectar was given to larvae, whereas 3.57% to dominant individuals and 95.94% of the collected prey were given to the larvae, 2.54% to the dominant members, while the remainder of both was given to the workers. Despite not being significant, it was possible to observe a difference in food distribution among larvae, with larger larvae receiving more food than others. When the forager returns to the nest with pulp, it adds this material to cells in 64.29% of the times. Males showed agitated behavior with the arrival of the foragers, and sometimes took the foraged material from them.
