Assessment Rationale:

This species is listed as Least Concern, since it has not been declining by more than 25% in the last ten years and its population size is probably larger than 10,000 adult individuals.

Geographic Range:

Restricted to the Canary Islands. Generally found from 200 to 2,500 m, although it has been recorded near the summit of Mount Teide on Tenerife at 3500 m. This is a European endemic species.

Habitat and Ecology

The Canary Blue can be found amongst scrub on rocky places, that are mostly at low altitudes and also on waste ground near human settlements. The larvae feed on many plant species, such as Cytisus canariensisSpartocytisus rubigenusLotus sessilifoliusL. hillebrandiiL. glaucusAdenocarpus viscosus and Teline stenopetala. At low altitudes, this species produces many overlapping generations and can be seen throughout the year. It is not known how many generations are produced and what the diapause stage might be on sites at high altitudes, such as Mount Teide on Tenerife.

Detailed habitat descriptions are not available.

Major Threat(s):

Although this is a European endemic with a restricted range, this species is not believed to face major threats at the European level.

Conservation Actions

This species occurs in a number of protected areas across its range. No specific conservation actions are needed at a European level. But since it has a restricted global range. The effects of conservation actions should be monitored closely by a Butterfly Monitoring Scheme.
