Summer heatwave encourages migrating butterflies

Many beautiful and rare species have been recently spotted in the UK that have not be seen here for decades.

According to experts the warm weather across Britain and Europe has sparked a “mass insect migration”.

The recent sighting of a yellow-legged tortoiseshell butterfly, which has only been seen once before in the UK in 1953, has confirmed suspicions among entomologists that we are set for an extraordinary summer of butterfly spotting.

“Looking at the weather map, the potential for mass insect movement all over Europe is very real – for butterflies, moths, dragonflies, hoverflies and ladybirds,” said Matthew Oates, a wildlife specialist at the National Trust.

“The arrival of the yellow-legged tortoiseshell raises the question, ‘Whatever next can we expect from migrants this year?’ This is amazing. It’s a very good year to be an entomologist – we’re very worked up this summer.”

The warm weather is attracting migrating insects because it provides ideal nurturing conditions which boosts populations. Increased competition for food forces the insects to disperse in search of new supplies, while the warm temperatures make areas that would normally be too cold hospitable.
