Local species abundance and altitudinal range occupied accounted for much of the variation in species distribution. Altitudinal range occupied by species was related to species distribution, but the most important variable accounting for species distribution was the local percentage abundance. Despite this, there was no evidence for age abundance. Despite this, there was no evidence for bimodality in the distributions of species incidence. A general trends for mean proboscis length in each locality to be greater in lowland localities exists, but this variable was not related to species distribution or abundance. Proboscis length spacings were studied among species in local assemblages and in most of the cases observed spacing did not differ from random expectations. The same patterns were demonstrated calculating spacings for ‘core' species in each local assemblage. Furthermore, species showed little tendency towards associations, so it may be concluded that bumblebee assemblages were irregularly structured and no clear patterns emerged from the present study.
