On1st May 2014 at approx 8am I came across what I believe to be four worker B.pascorum. They were static on seperate bluebell flowers; two each on separate stems a few inches apart. It had rained overnight and was still dank. All had damp fur and looked as if they had been out all night. The following day I returned & at 8.05am still cloudy at 10 degrees, found three of them still in situ seemingly unmoved, but this time their fur was dryer. On gently touching one it lazily stretched its back leg; I was relieved that it was ok. On 3rd May, same time but sunny & dry they had all moved on.
Do workers over-night outside?
Do they settle by pollen or nectar sources in inclement weather rather than risking a wet journey back to the nest?
