Aston’s Eyot/Kidneys has a typical selection for woodland edge and urban garden, though the huge nettlebeds don’t support the numbers of Vanessids* one might expect – this group’s caterpillars mostly feed on nettles. The Marbled White, lost since the 1980s, reappeared on the Kidneys in 2011; the Brown Argus has not been reported recently, probably because the grassy and short herb patches they favour have been replaced by nettles and other tall herbs. The list may well not be complete; sampling has been irregular in the past, but we have been making regular observations since 2011.
*Vanessids are the large showy ones: Peacock, Red Admiral, Small Tortoiseshell, Comma & Painted Lady
