Male territoriality in the carpenter bee Xylocopa virginica virginica
Animal Behaviour, 1983 Abstract Males of the carpenter bee Xylocopa v. virginica are territorial at nest sites, food plants, and landmarks such as boulders and houses. Their territories are defined as hover spaces of about 0.03 m 3 inside hemispherical 20-m-radius attack spaces. They copulated in or near nest-site and food-plant territories. Territorial males frequently
