Justification
The extent of occurrence (EOO) of this endemic butterfly is less than 5,000 km² (but larger than 100 km²), the number of locations is fewer than ten and it has a continuing decline. Therefore it is classified as Vulnerable at the global, European and the EU27 level.

Threats

Major Threats
This is a European endemic with a restricted range. The survival of the species is bound to its habitat, the laurel forest, which is still threatened although a part is legally protected. The main threats for laurel forests on the Canary Islands are tourist resorts and illegal building destroying part of the habitats, especially alongside roads or near settlements. Fires are another significant threat. Accidentally and intentionally set for livestock grazing, crop planting, timber and real estate speculation are also impacting the laurel forest.

Conservation Actions
This species occurs in a number of protected areas across its range. Since it has a restricted global range, its distribution and trend should be monitored closely, for example by a Butterfly Monitoring Scheme.
