Hardly any at all in the Vale of York. In fact, I've not seen any 'swarms' hanging in the air at all; just a few scattered individuals on tree trunks. The commonest species round here was B. johannis, this year, and then B. lanigerus and B. leucopterus in about similar numbers. Maybe the later species will fare better?

Bibio

We had a late swarm near the local beck on the particularly warm day we had I wonder how they survive the cold snaps we have had
