The Small Fan-footed Wave (Idaea biselata) is a Moth of the family Geometridae. It is common throughout Europe including the British Isles.

It is a small (wingspan 22–25 mm), easily missed species. The wings are creamy-white with darker bands with a small black discal spot on each wing. It sometimes flies short distances by day but mainly at night when it is attracted to light. The adults are on the wing from June to August[1].

The larva feeds on a variety of plants including asparagus, dandelion, knotgrass, oak, plantain and Rubus. The species overwinters as a larva.
