General information

This paper provides a comparative analysis of bees-plants and social wasps-plants interactions in "caatinga", a typical semi-arid vegetation of Northeastern Brazil, based on the author's previously published records from Itatim, Bahia State. Both interaction networks have similar topologies and are nested, asymmetrical and modular. Based on the higher connectance of the social wasps-plants network and in the higher clustering of niches among bees, the authors suggested that the later are more dependent on flowers, and consequently may be under higher interspecific competition.     

Data type and methodological remarks

Binary matrices describing bees-plants and social wasps-plants interactions with 13 species of social wasps visiting 42 plant species, and 12 bees species visiting 38 plant species. Samples were collected from November 1996 to November 1997, on a monthly basis, along a 3 km long and 20 m wide transect. Two collectors carefully and simultaneously inspected each flowering plant for 5 minutes and flower-visiting bees and wasps were captured using entomological nets.
