@duncan_dine The warden I spoke to seemed to think it was due to last year being so poor, ie wet spring then a cold spell in June. He thought it might take a year or two for the numbers to recover.
@duncan_dine@WWTSlimbridge I had some in my garden this time last year, but they are only showing leaves so far this year, these shown in your phot are very early.
Large Blue butterfly at Daneway banks - one one seen, think the cold weather has delayed them - this is apparently a female and fairly recently emerged.
@duncan_dine I’ll definitely go and look. Wonderful numbers of fragrant orchids in the other part of the butterfly reserve, the first time I’d seen those.
