During June and July 1976 the Institute of Terrestrial Ecology carried out a limited invertebrate survey on 18 sites in the Outer Hebrides.

Portable battery-operated UV light traps were installed at each site and left to operate for eight nights. Bad weather in June greatly reduced the numbers of Lepidoptera caught. During July moths were trapped at 16 of the sites. Details of the combined catches are given. Pitfall traps were also installed at all sites and all beetles, spiders, harvestmen, snails, millipedes, centipedes and woodlice have been identified. In addition a list of species of littoral Coleoptera recorded from 24 Hebridean localities is given.

This survey was part of a much wider project around the coasts of Scotland, commissioned by the Nature Conservancy Council, to whom a full report will be submitted when identification and analysis of the results has been completed.
