Fig. 1: Sampling trap design and composition (first three
letters of genus) for the bee community at 1, 10, 20, and 30 meters
above the ground with blue vane traps to represent the understory,
midstory, canopy, and above the canopy of the forest, respectively, in
the spring when floral resources were available and in the summer at
full leaf-out when floral resources were depleted. Traps in the
understory, midstory, and canopy were attached to a rope hung over a
high branch in the canopy and anchored to a nearby stem for easy
collection. The trap above the canopy was employed using a telescoping
hanger designed as described in Cunningham-Minnick et al. (in
press ), which had a rope threaded through the hanger that was anchored
to the stem in the understory to allow the trap to lowered along with
another cord at the trap to aid in lowering (not depicted). Numbers next
to pie charts represent total abundance across sites.
