Northern Ireland has only 6% of the land area of the UK but the relatively unspoilt coastline, mountains, lakes and rivers provide habitat for a wealth of butterflies and moths.
Northern Ireland has 25 butterfly species and nearly 1000 species of moth. There are two species of Wood White butterfly in Ireland: Real's Wood White and the Wood White. Réal's Wood White was only discovered in 2001. It has only been confirmed in Ireland, making it the only butterfly in Northern Ireland not found in the rest of Britain.
Other key butterfly species include the Large Heath, found on lowland raised bogs in the north and west, and the Marsh Fritillary, which has recently been found on several new breeding sites in Co. Tyrone and Co. Fermanagh.
The Argent & Sable moth can be found in Co. Fermanagh, which is also home to the only known site for the Irish Plume Moth.
