Life Style: A double brooded species that hibernates. It comes to light and can be found throughout the year. The larvae feed on Persicaria hydropiper, P. maculosa. Rumex acetosa, R. acetosella, R. hydrolapathum or Lythrum vulgaris. They pupate in a flimsy cocoon in the larval habitation.

Identification: This species stands erect on its front legs in a similar but less pronounced manner to Caloptilia species. It has wider wings than Caloptilia species. They are glossy dark brown to black with white or pale yellow blotches. There are two on the dorsum and two or three alternating on the costa. These are finely darker outlined. The blotches may be reduced or absent but the dark outline remains. There are a pair of small pale vague spots either side of the apex that remain on dark specimens. The larvae mine on the underside of a leaf to a blotch on the upper-side and then leave this to construct a cone by rolling the edge of a leaf partly cutting it out to do so. They construct several of these. More Info

Mine: Either the leaf or a good photograph required
