BUTTERFLIES OF LOCHABER

Introduction

 

Lochaber is an exciting place for butterflies, with 23 resident species and three migrants seen in recent years. 15 species are widespread in the district, and 11 are more localised or rare, or seen irregularly – see lists below. Several species have expanded their range into Lochaber in recent years, including Orange Tip, Peacock, Speckled Wood and Ringlet. For help with identification visit the Butterfly Conservation Highland Branch website http://www.highland-butterflies.org.uk/species/butterflies/index.html . A leaflet on Highland Butterflies is available from the Highland Council Ranger Service. The Highland Biological Recording Group has published an Atlas of butterflies in Highland and Moray http://www.highland-butterflies.org.uk/atlas.html which has tips for identification and details of flight periods.

 

 

Which are most special?

 

Seven of our species are UK BAP Priorities, as indicated in the list below. The Chequered Skipper is restricted in Britain to sites within just 30 miles of Fort William! The caterpillars feed on Purple Moor-grass in wet woodland glades. Lochaber is also a stronghold for the Mountain Ringlet which lives on mountain slopes east of the Great Glen.



  





Pearl-bordered Fritillary is another species which favours woodland glades, typically with bracken and plentiful violets on which the caterpillars feed. Marsh Fritillary can be found at only a small number of sites, generally close to the coast, where Devil’s-bit Scabious is abundant. The caterpillars feed on this plant and live in communal ‘webs’.

 





Where to see butterflies in Lochaber

Nature Reserves in Lochaber

 

Butterflies can be found throughout Lochaber, if the sun is shining (!), apart perhaps from the mountain summits, though species such as Red Admiral can even turn up there when ‘hilltopping’.

 

Many nature reserves in Lochaber are important for butterflies, but there is one site managed especially for butterflies at Loch Arkaig – Allt Mhuic Nature Reserve run jointly by Butterfly Conservation and Forestry Commission Scotland. Here you can see Chequered Skipper as well as commoner species such as Green-veined White and Scotch Argus.

 



Ariundle Oakwood NNR, Doire Donn SWT Reserve and Glen Nevis are also good sites for woodland butterflies including Chequered Skipper. For Pearl-bordered Fritillary and other woodland species try Glenborrodale RSPB Reserve. Ben Nevis, Glencoe and Creag Meagaidh have Mountain Ringlets and other upland specialists.
