|Colletes hederae burrows|
Apart from the colony at Barry there are no other known colonies in Wales to the east of Porthcawl, but there must be others out there. It is unusual for a solitary bee in being active so late in the year, as it specialises in taking pollen from Ivy flowers. It is also quite large and with obvious stripes on the abdomen, and hence is quite easy to recognise. BWARS have a mapping scheme for this species which includes a distribution map:
They would be delighted to receive any further Welsh records.
