Meadow Brown
Maniola jurtina
Overview
The Meadow Brown is Britain's most abundant butterfly and the default large brown of Sefton Coast dune grassland. Males are darker and more uniform; females are more orange-centred. It's unusual in that it remains active in cloudy, even cool conditions when other butterflies have stopped flying. In July, the dune grassland at Ainsdale can hold extraordinary numbers. The single eye spot near the forewing tip is always present.

Frequently Asked Questions
Why does the Meadow Brown fly in cloudy weather?
Unlike most butterflies which require warmth from sunshine to fly, Meadow Browns can remain active in cool, overcast conditions. Their dark coloration helps them absorb heat even from diffuse light. This adaptation allows them to feed and mate across a wider temperature range than sunshine-dependent species, giving them longer daily activity periods.
