The Blue Butterflies belong to the sub family Polyommatinae of the large Lycaenidae family.

There are 9 species of these little blue butterflies resident in the British Isles. Although, depending on species and gender, not all are blue.

In excess of 80 species of ‘blue’ butterfly occur in Europe. A few have strong migratory instincts such as the Long-tailed Blue which is occassionaly recorded in Southern England.

The mainly tropical metalmark butterflies of the family Riodinidae are closely related to the Lycaenidae. The only species found in the British Isle is shown at the bottom of the page.
