The images below show the butterflies likely to be found in the Countryside Park.
Some, the Peacock, Comma and Small Tortoiseshell, overwinter as an adult so may be seen for most of the year. Other residents spend the winter months as a caterpillar or a chrysalis only emerging in the spring or summer. The Clouded Yellow and the Painted Lady are migrants whose numbers vary each year according to weather conditions both here and abroad, as is the Red Admiral although a few of these seem to overwinter here too.
Although some butterflies overwinter as adults and can be seen earlier in the year, April is when many of them will start to emerge from the chrysalis stage. The Orange-tip is one of the first to appear and as it only has one brood each year most of them will be gone by June. Other species, such as the blues, the whites and the Speckled Wood, have two or three broods and can be seen for much longer. Some of our more numerous butterflies, like the Meadow Brown and the Gatekeeper, appear later in the summer, peaking in July and August.
More information about the butterflies found across Sussex can be found at the website of the Sussex branch of Butterfly Conservation.
Even more information and handy butterfly and moth identification pages can be found on the main Butterfly Conservation website.
A book about Sussex butterflies is "The Butterflies of Sussex" by Michael Blencowe and Neil Hulme (2017).
A good field guide is "Britain's Butterflies" (2015) from the "Wild Guides" series.
