Pieris rapae (Small White)
General description:
Although a common butterfly throughout the UK, there are only a very small number of records for the islands. It is, however, possible that it is overlooked or confused with the more common green-veined white (Pieris napi).
Diagnostic description:
The large and small white butterflies can usually be distinguished by size. There are differences in the shape of the black mark on the forewing tip. In the large white, this black tip wraps around both the leading edge and trailing edge with the inner boundary strongly curved. In the small white the black tip has a more or less straight inner line and it doesn't extend very far along the trailing edge. The plain underwing distinguishes the small fom the green-veined white.
