Start: Noon April 1
End: 9:30 a.m. April 2
Habitat: Bottomland Mixed forest with many spring beauties in bloom
Bees: Osmia, Andrena, Nomada
Experiment: 21 bowls each of 3.25 ounce white solo brand bowls and similar sized cut down styrofoam cups, the two types were alternated in a transect through the woods and placed 5 m apart.
Results below are styrofoam in the left column and solo in the right column. They are presented as pairs, but in reality they are simply adjacent to one another in the transect. Numbers are total number of bees.
Helping on the this experiment were Molly Passacantando and Lisa Guide (Many thanks).
Results are extremely clear. Styrofoam captures are much less. Totals are much lower and in adjacent bowls capture in styrofoam is always lower.
Not sure why, both are bright white....possibly bees can climb out of Styrofoam more easily, but no sign of soggy bees on or near the cups.
