1. Large white: 396,510 sightings
Large whites were the most common butterflies spotted in the UK this year with a record number of sightings, more than doubling from last year’s Big Butterfly Count. Recognisable by their creamy white wings with black L-shaped markings, they are also commonly referred to as cabbage butterflies or cabbage whites due to their staple diet. Their numbers are up 47% over the past 15 years

2. Small white: 318,762 sightings
Small whites were the second most sighted butterflies in the count, and like the large whites, this year also saw their highest ever recorded number of sightings, up more than double from last year. Small whites are part of the same family of butterflies as the large white.

3. Gatekeeper: 236,425 sightings
Gatekeepers took the number one spot in the count last year. While the number of Gatekeepers spotted this year has remained similar to last year, the population has suffered a decline of around a quarter over the past 15 years. Gatekeepers are so named as they are often spotted around gates and hedgerows where there is an abundance of flowers.

4. Red admiral: 166,289 sightings
Red admirals have fared among the best in the count with a steady year-on-year increase of sightings reported, and a 52% increase in their numbers over the past 15 years. This is probably due to global heating meaning they can delay their winter migration to warmer regions in southern Europe and north Africa, and can sometimes even overwinter in the UK.

5. Meadow brown: 133,025 sightings
The usually abundant meadow brown had its fourth-worst result on record, possibly because weather conditions meant it was on the wing earlier than usual and some butterflies had finished flying by the time the count began on 18 July

6. Peacock: 96,155 sightings
The Peacock is named for the distinctive topside of its wings which mimic eyes to startle and confuse predators while its underside provides camouflage blending in with dead leaves. Numbers of Peacock sightings have increased by more than double compared with last year

7. Speckled wood: 53,423 sightings
The number of speckled wood butterflies, with their distinctive yellow specks, has seen a similar number of sightings compared with last year, but has seen a decrease in the overall population by 35% in the past 15 years. Unlike most other butterflies, the speckled wood does not feed on flowers but on honeydew from trees.

8. Comma: 43,062 sightings
The striking comma, with its scalloped edges and burnt orange colouring, had a 42% increase in sightings compared to last year. It is one few butterfly species to have maintained a consistent population since the count began, and has made a remarkable comeback since a severe decline in numbers in the twentieth century.

10. Green-veined white: 39,272 sightings
Green-veined Whites are known for their prominent green veins which set them apart from the small white. It also bounced back from its worst year on record, but to a lesser degree than the common blue. It was 67% up on 2024 but still at half the abundance of 2010 levels
