Apis mellifera - collecting sap for propolis

I revisited the pile of monkey puzzle slices at Brookwood Cemetery this week, to see if the bees were still around, if anything they were there in greater numbers, and more sap had oozed ot for them, in some places collecting on the grass below. It was evident that the much warmer weather had softened the sap too, as they seemed to be having more trouble keeping the sticky resin in the right places. This one is cleaning it's antenna.
