Abstract
Parasitoid wasps (Hymenoptera) have been observed to have abnormally high diversity at high elevations and latitudes. I hypothesized Hymenoptera small body size and high trophic efficiency decouple their richness from the environmental energy budget. I surveyed solitary Hymenoptera at 94 sites 25-1350m.a.s.l. in Vermont. Hymenoptera richness decreased then increased with elevation. The slopes of individual lineages’ diversity-elevation relationships were negatively correlated with body size and positively with trophic efficiency. Large, inefficient taxa declined with elevation, while parasitoid diversity increased 975-1325m. These findings highlight the importance of physically small taxa in Hymenoptera surveys and how conserved traits can drive community assembly.
