Overview
The Large White is the other 'cabbage white' — bigger, stronger and more striking than Small White, with a large black wingtip that extends further down the wing. In good years, immigration from the continent swells UK numbers considerably. The yellow, black-striped caterpillars of the Large White are very different from those of the Small White (which are green and inconspicuous). Large Whites fly powerfully and cover more ground than Small Whites.

Frequently Asked Questions
Are Large White butterflies migrating to the Sefton Coast?
Yes. The UK Large White population includes both resident individuals and immigrants from the continent. In some years, large numbers cross the Channel and arrive on UK coasts including the Sefton Coast. These migratory movements — sometimes visible as streams of butterflies flying in from the sea — are one of the phenomena of coastal butterfly watching.
