The transect route at New Ferry Butterfly Park is 783 metres long with 8 sections. It goes through a variety of habitats, including wooded areas, grassland/meadows, and scrub, featuring both food plants for caterpillars and nectar plants for adult butterflies, moths, and other insects.
In 2026, we recorded 1,099 individual butterflies across 21 species. This is a similar result to 2025, showing a slight increase in numbers from 1,050 in 2025 to 1,099 in 2026.
Brimstone
Compared with the 2025 data, the majority of species were in an increase, albeit to varying degrees. These included the Small Skipper and Essex Skipper combined, Brimstone, Small White, Green-veined White, Orange Tip, Small Copper, Holly Blue, Red Admiral, Painted Lady, Peacock, Gatekeeper, and Meadow Brown.
Holly Blue Gatekeeper
The species that did particularly well were the Brimstone, whose numbers increased from 48 in 2025 to 80; the Small Copper, rising from 8 to 40; the Holly Blue, from 20 to 87; the Gatekeeper, from 79 to 111; and the Meadow Brown, from 88 to 115. Additionally, the Brimstone, Holly Blue, and Gatekeeper achieved higher counts this year than in any previous year.
Small Copper 
Sorrel planted at the Butterfly Park as food for the Small Copper caterpillars
A decade of effort has been made to increase the stock of Sheep’s Sorrel (a caterpillar food plant) at the Park, and it is incredibly encouraging to see the Small Copper flourishing this year. Both the Small Copper and Brimstone have created exciting educational opportunities for children and adults visiting the Park to witness eggs and growing caterpillars first-hand.
Speckled Wood
Conversely, numbers dipped for the Large White, Common Blue, Small Tortoiseshell, Comma, and Speckled Wood. Although the number of Speckled Wood was lower this year (162) than in 2025 (272), it remains higher than in the years prior to 2025.
Small Tortoiseshell
Habitat management work will continue during the winter months while the Park is closed to visitors. This work includes cutting back brambles to encourage the growth of grass and wildflower species, planting more caterpillar food plants, and scything the meadows. We hope for more insect-friendly weather next year.

What Is a Butterfly Transect Walk?
A butterfly transect walk is a recording method used to monitor the abundance, diversity, distribution, and long-term population trends of butterflies. Under the Cheshire and Wirral Branch of Butterfly Conservation, there are currently 68 established transects in Wirral.
The data collected through these transects walks feeds into the database at the United Kingdom Butterfly Monitoring Scheme (UKBMS), providing valuable insights into butterfly populations and how they change over time across the UK.
Watch out for the next Blog from Yan and Charles all about carrying out butterfly transects.
