Mining bee in chalk grassland. No obvious nectar plant.
No interactions present.
Certainly looks like a species of Colletes, and the time of year makes C. hederae possible. See if you can find it at any ivy flowers nearby. See:
Entomologist and biological recorder
Bryan Pinchen recorded the bee at Martin Down NNR in about 2003 - one of the very first inland records in UK. In the last few years it has turned up in the Martin area at Ebbesbourne Wake, all around Sixpenny Handley, and in abundance at Homington and Salisbury. I would LOVE to know how far away the nearest flowering Ivy is.
