Population densities and biomass of Neotropical social wasps (Hymenoptera, Vespidae) related to colony size, hunting range and wasp size
At a locality near Brasilia the sizes of hunting areas and of colonies of 13 species of social wasps varied greatly. Size of the hunting area varied 152 fold and was strongly related to the number of adult wasps per colony which varied 400 fold. The total number of adults of the 13 species was estimated at 182.9/ ha (range 7.1 fold among the species) and their total biomass was 1.6 kg/ ha (range 3.6 fold). Hunting range was not significantly related to body size. Variation in wing area (11.3 fold) was similar to that of the fresh weight of the adult female (10.7 fold). Eleven species showed habitat preferences where they hunted. Models relating prey size to the distance prey are carried are discussed.
