Declana floccosa, the forest semilooper, is a moth of the family Geometridae. It is endemic to New Zealand.[1] It was first described by Francis Walker in 1863 using specimens obtained from Colonel Bolton.[2]

The wingspan of this species is 27–35 mm and is extremely variable in colour and patterning.[3][4]

The larvae feed on a wide range of native and exotic broad-leaved and coniferous shrubs and trees. Exotic hosts include Pinus radiata and other Pinus species, Pseudotsuga menziesii, Larix and Eucalyptus.[3] Native hosts include Muehlenbeckia australis.[5]
