Will you be joining this year's Big Butterfly Count?

Some of us may be struggling with the warm weather, but conservationists have said it could mean good news for butterflies.

Wildlife charity Butterfly Conservation said that a warm, dry spring this year has meant that butterflies could be out in force this summer, with the UK heading for a bumper butterfly season.

Members of the public are also being asked to join its annual Big Butterfly Count from 17 July - 9 August, which aims to find out how butterflies have been doing this year.

To take part, people need to spend 15 minutes outside in any sunny spot, such as their garden, park or local countryside, and report their sightings.

Butterfly Conservation said heatwaves, warm dry spells and occasional heavy rain have created ideal conditions for butterfly breeding and caterpillar growth.

Some species, like small coppers and holly blues, have already been seen in large numbers. Whilst peacock, red admiral and brimstones are also having a good start to the year.

Experts at the charity also say there could be signs of a possible "painted lady summer" – when the migrant butterfly arrives in the UK in large numbers.

But to know for sure, they are asking people across the country to take part in the count and tell them what they are seeing.

Why is the Big Butterfly Count important?

The survey helps scientists understand where some of the country's most common butterflies and day-flying moths are doing well, or are struggling, or moving because of climate change and changes to habitat.

Four fifths (80%) of butterfly species have declined in the past 50 years.

Conservationists have said this is a result of habitat loss, pollution and climate change.

The 2024 count delivered the worst results in the scheme's history, when the charity declared a "butterfly emergency".

A hot, dry, and sunny 2025 helped to improve the situation for many species, and they're now hoping that with this year's spring being one of the hottest on record, it could improve butterfly numbers even more.

But, the charity has said continued improvements are not guaranteed – and they're still fighting against long-term declines.

Butterfly Conservation's head of engagement, Kate Merry, said: "A bright spring is only ever part of the story, which is why we need people out there taking part in the Big Butterfly Count this summer.

"We genuinely don't yet know how this year will unfold, and the only way to find out is for people to tell us what they're seeing in their own gardens and green spaces."

Will you take part in the Big Butterlfy Count? Do you see many butterflies outside around where you live?
