Andrena nitida, October 2022, Exeter, UK.

This species is usually seen in flight from April to June/July. Unfortunately this specimen looked a bit tired this late on in the year...

There is an unusual small peak of observations on iNaturalist from September to November (small peak also seen on UK NBN atlas in October). Does anyone know if this mini peak well known and has it been studied?
