Population:

This is a very local and rare European endemic, restricted to (semi-) natural areas on La Palma, Canary Islands. It is not known how large the population is, but numbers might well be under 10,000 adults.

Habitat and Ecology

This Grayling is confined to one of the Canary Islands, La Palma. It can be found in rocky gullies surrounded by laurel or pine forest. It has one generation a year (Tolman & Lewington 2008). Detailed habitat descriptions are not available.

Major Threat(s):

This species is restricted to few locations on one island. It is threatened by tourist activities and fires.

Conservation Actions

As this species has a restricted global range and is very rare, its distribution and trend should be monitored closely, for example by a Butterfly Monitoring Scheme.
