Corbiculae (pollen baskets) are visible, and contain yellow pollen stores. In early spring, these bees can be found pollinating the wild blackberries that abound in the park. In such instances, orphaned colonies are considered “parasocial” . Males have predominantly green legs, and pale yellow tarsi.

Some, like the carpenters, can become pests, drilling holes in wooden building materials to make nests. [Photo © Copyright 2016 Julio Sharp]. Throughout the summer, they are regular visitors to the sunflower plantings in Stone Barns' vegetable fields. Parasocial colonies allow for more diversity of genetic material in the hive. Can they be blue as well as shades of green? They are then transferred into the enlarged hind tibiae through the hole. Note that the last few segments on the end of the bee's sternum (the underside of its abdomen) are black.
