Wingspan 12 - 17 mm. Can be very similar to Spilonota laricana. Specimens with an ochreous tinge to the ground colour should be S.ocellana.
A quite variable species in density and colour of the markings, this moth can usually be identified by the well-defined darker basal patch and the small blackish triangular blotch on each forewing, forming a diamond shape when at rest.

The larva feeds at first on the underside of a leaf, living in an open-ended silken tube. Overwinters as an early instar in a silken hibernaculum on a twig, branch or bud. In spring the larva eats into leaf and flower buds causing them to wither, later feeds in an untidy spinning of several leaves.
The adults come to light.

Flight periods

The adults have been seen from mid-May towards late October. Most observations during July.
