This website contains information on over 320 species of Lepidoptera recorded in the Outer Hebrides, mainly in the Uists and Benbecula, since 2009. The majority have been caught in light traps (125w mercury vapour lamps and actinic light traps) with field observation and butterfly nets used for recording day-flying moths and butterflies.
Fourteen species of butterfly are regularly recorded on the islands: Large White, Small White, Green-veined White, Common Blue, Red Admiral, Painted Lady, Small Tortoiseshell, Peacock, Dark Green Fritillary, Grayling, Meadow Brown, Small Heath and Large Heath. Speckled Wood has been recorded on Lewis since 2004, the Ringlet on South Uist since 2008 and the Orange-tip on Lewis in 2014. There are rare occurrences of the Clouded Yellow (migrant from southern Europe) and there have been two records of the Monarch (North American migrant species).
This site is primarily a photographic inventory with a short text. Information on their distribution is available via the National Biodiversity Network Gateway.
The accounts of individual species can be accessed through the A-Z lists of scientific and common names or by using the search facility. There is a separate list for butterflies.
