19 May 2021
Swathes of Horseshoe Vetch, Hippocrepis comosa, covered the lower slopes of Mill Hill on a cloudy afternoon inimical for watching butterflies.

12 May 2021
Five o'clock in the afternoon is a bit late in the day for seeing active butterflies on the lower slopes of Mill Hill as most of them will have gone to roost. I did manage to spot my first male Adonis Blue (not confirmed -subsequently thought to be a Common Blue) , and my first of the year Small Copper visiting the abundant Horseshoe Vetch, Hippocrepis comosa. A flock of up to a dozen corvids, mostly Jackdaws. were persistently feeding on something amongst the short vegetation on the steeper slopes. A Peacock Butterfly flew down and I disturbed a handful of Grizzled Skippers.

7 May 2021
Tripping over butterflies at Mill Hill today with a grand total of 14 species recorded. Dozens of Dingy Skipper & Grizzled Skipper, Green-veined White, Small White, Brimstone and a singleton Orange-tip doing the rounds. Wall are coming along nicely with at least half a dozen bobbing around, a female already ovipositing. A handful of Small Copper seeing off all-comers which included my first Common Blue of the year, around 6 males seen. Green Hairstreak also doing well, regularly getting stuck in with the multi species aerial brawls, again about half a dozen active. The afternoon brought out 4 or 5 fresh looking Peacock and there were good numbers of fresh immigrant Red Admirals, a female was seen egg laying (from the state of some they must have come via Jersey!). A single Comma made a very brief appearance (unable to tell if it were an early hutchinsoni or a late hibernator). The day started off with a rare Sussex sight of a female Small Tortoiseshell avidly investigating some nettle on the edge of the horse paddocks on the south side of the Shoreham Bypass.
