Distribution
Imago
Wingspan 12–17 mm. It has previously been regarded as a form of Spilonota ocellana.
The basal area, triangular pretornal mark and termen are all marked dark. The ocellus is extensively black dashed and suffused grey. A dark suffusion from the costa at one half.
This species can be similar to Spilonota ocellana but S. laricana has a more irregular outer edge to the basal patch, more extensive grey suffusion in the costal half and ocellus, the black dashes in the ocellus are more extensive and the costal suffusion at one half more prominent.
When dark forms of Spilonota ocellana occur the paler areas of the wing are all darkened where-as S. laricana retains the pale dorsal central area.
