Common Blue - Polyommatus icarus


The common blue is a butterfly every watcher should commit to memory - blues are readily identified by how they differ from this standard species. The upperside of the male has a narrow black border (though it is wider in some forms)and is otherwise largely unmarked. The underside of both sexes is a typical jewelled 'polyommatine' pattern, with a spot in the middle of the cell. In the lower picture here the cell spot is partly covered but can just be seen.Pictures.Females are generally brown, with some blue scaling towards the bases of the wings and orange submarginal lunules. However, in some places very blue female forms may be found. The upper picture here is of such a female - the form is quite common on the East Suffolk coast. Pictures
