The Big Butterfly Count




The Big Butterfly Count

The results for the Big Butterfly Count for 2022 show a continuing overall decline in numbers – a 2.8% drop for the UK but an increase of 9% for Wales was encouraging. The butterfly with the biggest rate of decline was the Marbled White and this was the same result for Wales. Wales also showed significant reductions for Ringlet, Large White and Small White. The biggest increases were for the Common Blue and Holly Blue but with Wales recording the biggest increases for Holly Blue and Brimstone. We have noticed Holly Blues doing well in Wenvoe particularly along the trees in the school and in gardens. A blue butterfly flying higher up, say around 5 to 10 metres above the ground, is likely to be a Holly Blue.

The Speckled Wood (see photo) has done well both in Wales and throughout the UK with several local people reporting them in their gardens. One interesting behaviour we have noticed is how territorial they can be. One adopted a small section of patio, turning up by mid-morning every day and then furiously defending it against any other trespassing butterflies, no matter which species. Even the occasional falling leaf would be checked out and warned off.

Those who want to help our butterflies are encouraged to plant wildlife-friendly habitats – for instance Holly and flowering Ivy for the Holly Blue and Hop, Elm and Nettles for the Comma. The caterpillar of the Speckled Wood favours our taller wild grasses such as Cocksfoot, Yorkshire Fog and False Brome so if you have sufficient space for a wild area, that can help all sorts of wildlife
