Callisto denticulella

Leaf-mine: The young larvae mine the leaves, causing a gallery followed by a semi-translucent blotch on the upper surface of the leaf. It then vacates this and folds the edge of a leaf down to feed within, usually twice, before pupating externally among detritus (UKMoths). The leaf-mine is also illustrated in British leafminers and Nederlandse bladmineerders.

Larva: Details unknown.

Pupa: Details unknown.
