A hectic few days during this heatwave. 86 species of moth last night alone and well over 100 this week. The Beddington moth year list is now on 283, two away from the all time record.
I've been running the MV trap at the obs and also an additional actinic Heath trap which was situated next to the oaks on Biker's field.
Tawny Owls were calling outside the obs on Thursday evening, there were Green and Common Sandpipers calling yesterday at dusk presumably preparing for migration and the bushes are now peppered with calling Chiffchaffs. There's been just under 100 Swifts also in the evening- numbers are now falling from highs of 500+ in the spring/summer.
What looked like Purple Hairstreaks were flying at the top of the Mitcham Common oaks.
