Actively flying bee on a hot day

Observation - Actively flying bee on a hot day - UK and Ireland. Description: I saw this insect actively and continuously flying around within a localized area (There seemed to be a pale blue sheen to it). When it did occasionally stop, it proved to be a smallish bee. What looked like the same individual was still active about 20 m

I saw this insect actively and continuously flying around within a localized area (There seemed to be a pale blue sheen to it). When it did occasionally stop, it proved to be a smallish bee. What looked like the same individual was still active about 20 minutes later (Images 3 and 4).
