The wingspan is 12–17 mm. The forewing has, as is usual in this genus, a comma-shaped white spot at the dorsal edge, this is without a brown middle strip. Just outside this spot there is a short, silver-coloured cross-strip and four drop-shaped black spots. At the front edge there are numerous small white cross spots. The hindwings are brown, but shiny white at the root.It differs from Grapholita orobana as follows : palpi partly dark fuscous; antennae of male unusually long and thick; forewings with costa in male straighter, dorsal blotch narrow and less curved, hindwings in male with dark border still broader, in female wholly dark fuscous.[3]
The larvae feed on Lathyrus spp. and Vicia spp., eating the ripening seeds. The adults fly in the sunshine in May–June
