Butterflies - Small Blue (Cupido minimus)

Also known as the 'Little Blue', the Small Blue is the smallest native British Butterfly and is easily overlooked. The upper wings of this tiny butterfly tend to be a dusky brown fringed with white with a sheen of blue scales radiating out from the body. Its undersides are a dull blue-gray colour with small dark spots again with a hint of blue extending from the body.

Males are highly territorial selecting a prominent perch in a sheltered position. The females tend to disperse to lay eggs on the buds and flowers of the larval food plant Kidney Vetch. Males and females are easily found in communal roosts during the early evening as the sun begins to set.

Kidney Vetch (Anthyllis vulneraria)

The main requirements of the Small Blue are dry sheltered areas of grassland where Kidney Vetch grows. Sites must have sparse or eroding vegetation with bare ground where Kidney Vetch seedlings can become established and where flowering Kidney Vetch is abundant.

The Small Blue is best looked for on chalk and limestone grassland, quarries, gravel pits, and disused railways.
