Robber fly species richness was determined for each understory level.
Simpson's diversity index (Simpson, 1949) was used to measure robber fly diversity at each understory level.
The multi-response permutation procedure (MRPP) was used to compare robber fly species composition/relative abundance between the two understory levels and to examine heterogeneity of robber fly species composition/relative abundance within each level.
June was the most active month for robber fly captures with 52, and the peak collection occurred on 23 June (Fig.
Our results revealed no significant differences in species diversity or richness (based on rarefaction) in relation to trap height, but robber fly abundance was greater in the lower understory traps, with 70.
2009), which may produce environmental conditions conducive to a somewhat different robber fly species composition.
flavipes was by far the most abundant robber fly species found at Post Wildlife Sanctuary, with O.
