The first butterflies of the season are always adults newly emerged from hibernation: brimstone, peacock and small tortoiseshell are the earliest, beautiful flashes of colour to herald the spring.

But our butterflies are in trouble. A third of Britain’s butterfly species are threatened and three-quarters are in decline. An organisation called Butterfly Conservation needs current information about butterflies in order to understand their past decline and plan for their future.
They are asking people to download a free app, iRecord Butterflies; it will guide you through the identification of any butterfly that you see in the UK and allow you to add your sighting to millions of other valuable records that inform the vitally important work of conserving butterfly habitat and species.
Sightings logged with iRecord Butterflies will be passed onto the Butterflies for the New Millennium national recording scheme run by Butterfly Conservation, with support from the Biological Records Centre. This is a long-running scheme that has recorded millions of butterfly sightings over decades. Your sightings will be used to understand what is causing the decline in butterfly numbers and to plan conservation work to help threatened species.
Here are two UK BAP Priority Species, both of which have been identified in the park:  white letter hairstreak Satyrium w-album  wall brown Lasiommata megera. They will need your help if they are to survive:
