As with many transect this year sees a big rise in Gatekeeper numbers as the species recovers from drought in early 2020 but all the browns have benefited to make for the best year so far. As elsewhere the Vanessids have had a bad year particularly Comma apart from the Small Tortoiseshell whose boom these last two years continues. The cabbage whites also had a pretty good year. Unfotunately Wall has not returned. Holy Blue was absent and had a disasterous oear as it did elesewhere. Small Skipper has maintained it numbers after a rapid rise in the last two years but Large Skipper remains absent
