Looking back through iRecord in 2019 the site, Anderton Park, had a Common Blue on 8th April. It seems to be just north of a chemical works - probably a warm microclimate.BDS reporting that a Common Blue damsel was recorded in Cheshire on 29 March. Seems an odd place to get the first sighting of the year, so perhaps another one that's been accidentally accelerated in a fish tank? Or perhaps just a very odd local microclimate.
Yes, north of Swindon, just before you reach the boundary with Gloucestershire. It's the site of the famous snakeshead fritillary population. I see on iRecord that they were recorded there for the first time last year so perhaps spreading from the small population that's been in the Water Park for a while. So a great record both for the early date and the location.Hairy Dragonfly (2 probably 3) reported from Cricklade North Meadows SSSI (near Swindon I think) on 13.04.21
