Scientific name: Leptidea juvernica
As its name suggests, this butterfly is very difficult to distinguish from the Wood White.
This butterfly occurs in only Ireland. It was only discovered to be different from the Wood White in 2001, and more recently its identification was changed again to this new name.
Only found in Ireland where it is widespread. Upperwings white with rounded edges. Males have black mark in edge of forewing. Undersides white with indistinct grey or greenish markings. Wood White is very similar, but in Ireland seems to be restricted to the Burren region.
