The larvae have been recorded feeding on plants in the genera Haloragis, Gaultheria and Geranium.
In volcanic areas of southern Chile Gaultheria mucronata is one of the dominant plant species above the tree line.
In English, it is known as salal, shallon, or simply Gaultheria in Britain.
Gaultheria trichophylla, commonly known as Himalayan snowberry, is a species of plant in the heath and heather family, native to the Himalayas.
Mild sweeteners such as fireweed (Epilobium angustifolium), camas bulb (Camassia quamash) or sweet berries such as salal berries (Gaultheria shallon), or thimbleberries (Rubus parviflorus) are occasionally added.
The compound methyl salicylate was first isolated (from the plant Gaultheria procumbens) in 1843 by the French chemist Auguste André Thomas Cahours (1813-1891), who identified it as an ester of salicylic acid and methanol.
