Big Butterfly Count 2021 – The Results Are In ...

Thank you to everyone who took part in the Big Butterfly Count 2021. The results are in.

Butterfly Conservation, which counted butterflies and moths between 16 July and 8 August, said the results marked the lowest numbers since the Big Butterfly Count started 12 years ago and called for urgent action to be taken.

Zoë Randle, a senior surveys officer at Butterfly Conservation, said an extremely wet May, which brought the UK's fourth-highest amount of rainfall on record for the month, was a significant factor for butterfly numbers, hindering their breeding and feeding. 'Butterflies don't like the rain at all, they're coldblooded insects. Effectively they're solar-powered', she said.

The 'Top 10' species counted in the UK in the Big Butterfly Count 2021

• Small White (252,151 counted; -5% on 2020)
• Large White (229,218; -16%)
• Meadow Brown (197,060; +33%)
• Gatekeeper (133,726; -30%)

• Small Tortoiseshell (38,543; -32%)
• Marbled White (28,704; +213%)

Butterflies form a vital part of the food chain and are considered significant indicators of the health of the environment. Julie Williams, the charity's chief executive, said: 'The facts are clear. Nature is in crisis and we need urgent action, not just to prevent further species losses but to rebuild biodiversity'.
