Wood white sightings at Fineshade Wood rose from 73 to 746 in a year

Volunteers recorded 746 wood white sightings at Fineshade Wood this year, up from 73 in 2025. Butterfly Conservation published the count on October 27, 2026, two years after the species was put back into the Northamptonshire woodland.

In 2024 the team moved 20 adults from Hazelborough Forest and Bucknell Wood, both Forestry England sites, with money from Natural England's Species Recovery Programme. Another 23 went out last summer. The charity said sightings per hour are nearly ten times last year's. One volunteer saw 42 on July 15 and the team reads those as a second generation, offspring of butterflies that flew in May. Sightings are not a census of individual insects. The same butterfly can be counted more than once.

Wood whites have cream wings with furry edges. Since 1992 their range in southern England and eastern Wales has shrunk by about 76 percent, and they now hang on in about a dozen fragments. They need sunny, sheltered rides and plants such as bird's-foot trefoil and meadow vetchling. Jamie Wildman, the charity's central England conservation manager, said the speed of the increase surprised the counters. Dan Hoare, director of nature recovery, said a warm spring may have sped up caterpillars where the plants sit in damp, grassy ditch edges, and that a network of rides lets adults shift to cooler grass in a heatwave. England's driest July on record, since the surveys began this year, is expected to press on the next larvae. Forestry England's Mark Underwood said staff and visitors have been seeing the butterflies in the wood. The charity hopes Fineshade can seed the surrounding forest. That spread is a hope. The number in hand is this year's sightings.
