16.013 Kessleria fasciapennella (Stainton, 1849)
< back
vacated mine


Food Plant: Parnassia palustris (Grass of Parnassus)

Egg: on the leaf petiole or at the base of a leaf

Mine: June-July

Notes: Initially mines a leaf. The upper surface mine is usually adjacent to the leaf margin and gently sinuous with irregularly scattered frass. a dead larva is shown in the mine. Occasionally the mines may widen to form small blotches. After the leaf is mined the larva feeds, in a web, on the rosette leaves and stem. This web is made at the base of the plant, amongst the leaf litter and moss.
