Host plants:
The species feeds especially on Rumex lunaria, but also Rumex maderensis and other herbaceous plants.
Habitat:
Eupithecia tenerifensis colonizes ravines (barrancos), forest edges, dry slopes, moist clearings and many other places where Rumex lunaria or other host plants occur.
Life cycle:
The moths can be observed throughout the year, but occur especially common in the winter half of the year. The caterpillars are also found throughout the year. A part of the pupae aestivate and releases the moths not until the autumn.
Endangerment factors:
On some islands the habitat for the indigenous nature already dwindled sharply due to the extreme urban sprawl (Tenerife, Gran Canaria) or intensive agricultural use (La Palma: banana plantations) of the coastal regions. But Eupithecia tenerifensis is relatively adaptable and still one of the more common ones.
Remarks:
Eupithecia tenerifensis is found on the western Canary Islands and Gran Canaria.
