Over many decades, people have investigated Hebridean insects but few have collected from Canna and Sanday as Dr John Lorne Campbell did.

To this day, Hebridean insects remain poorly known, having only been patchily recorded. Other than Campbell, practically no-one else has attempted to record Hebridean insects over such an extended period using a standardised method, such as the mercury vapour moth trap.

The insect collection and its associated data represent a unique environmental record, which is of great interest to scientists. Comparing Dr Campbell’s published records and notebooks to modern-day finds may help to assess the impact of environmental change both in the islands and more widely across Scotland.

There has always been a desire to improve public access to the Canna House Lepidoptera Collection. Due to its very fragile nature, it will not be possible to allow physical access to the collection by the public in the future. This led Trust specialists to look for alternatives, with digital access being the most exciting and likely option. Find out more about our recent Lepidoptera conservation project.
