Sightings of a long-distance migrant butterfly have been recorded the length and breadth of Lewis and Harris, during a mass-migration which has blanketed Britain.

A call from the Butterfly Conservation Society for sightings of the Painted Lady butterfly has brought in records from locations as far apart as Strond in Harris, Barvas, Shawbost and Laxdale, with a noticeable cluster of sightings around Ness.

The Painted Lady is a long-distance migrant, which causes the most spectacular butterfly migrations observed in Britain and Ireland. Each year, it spreads northwards from the desert fringes of North Africa, the Middle East and central Asia, reaching Britain and Ireland to breed. The offspring then emigrate southwards.

Numbers vary greatly from year to year, but the last mass immigration occurred during 2009.

July saw a peak in sightings around Lewis and Harris, with numbers as high as 50 recorded in some locations. The butterfly typically feeds on thistles and other wildflowers, but is also attracted by highly scented garden flowers.
