Callisto denticulella

(Thunberg, 1794)

Wingspan c.11 mm.

Distributed throughout much of the British Isles, Callisto denticulella frequents orchards and gardens where apple trees are present, flying in May and June.

The young larvae mine the leaves of the foodplant, apple (Malus), 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.
