Document Summary
Male mating strategies in the eastern carpenter bee, xylocopa virginica. Xylocopa virginica is a large carpenter bee that nests in milled lumber. Males emerge prior to females in the spring to and return to those nests at night. They defend territories close to nests and at floral resources. Nests located where there is milled lumber. Males are less aggressive to males from the same nest. Suggests a dear enemy effect where after territories are established familiar individuals are less aggressive to each other. Males guard territories closest to nest entrances to gain access to receptive females that frequent nests between nectar and pollen trips. Prediction: males will establish and defend territories closest to nest entrances. Males defend territories by hovering for hours on end waiting for receptive females to return to or leave nests. Bridge d: northside: 1 nest, southside: 25 nests, males hover near nest entrances most frequently.
