14-11-2018 MONTE CORONA, VALENCIA - WAVE MOTH (Idaea filicata)
Idaea filicata is a moth of the family Geometridae. It is found in Southern Europe and the Near East.
The species has a wingspan of 12–21 mm. The adults fly at night from May to September in two to three generations.
Idaea filicata is a moth of the Geometridae family with a wingspan of about 15 mm, ivory white with brown spots on the wings and abdomen. With its wings spread out, the image is that of a white fan with a dark brown circular segment in the centre that reaches halfway and, beyond, a concentric arc of the same brown. The concordance between the front and back wings to form this geometric image is remarkable. On the edge of the wings it has a fringe of white hairs. These white hairs are also found on the back of the thorax, although the specimen in the image has lost them. The legs and antennae are also white.
The image of the adult was obtained in a building, attracted by the light.
The caterpillar is of an indistinct dark colour, between grey and reddish brown, with the segments wrinkled in an apparent second-order segmentation. It appears to feed on numerous herbs when they begin to decay.
In the Iberian Peninsula, Idaea filicata is distributed throughout the Mediterranean lands from Murcia to the north and in the Ebro depression; however, it is absent in the western half.
