Anthophora plumipes is back!
Experiments by Graham Stone and colleagues have studied the ability of A. plumipes to increase their internal temperature. Accordingly, at the 8 degrees in which bees were active this morning, their body temperature is likely to have been around 28oC. The males patrolled constantly in a route around the garden and occasionally stopped to feed in some small Daffodils and Primroses. Males always emerge first from the nest where they were born, followed by the females. This is so because in the long tunnels where females nest, they lay fertilised eggs first (which will become females) and the last ones unfertilised (which will become males) and the bees emerge in reverse order of laying as the last eggs laid are closer to the opening.
