Elongated, lower-surface, in the end tubular contracted tentiform mine, usually starting at a small distance from the midrib. The lower epidermis with many weak wrinkles but no clear folds. Often several mines in a leaf. All frass is accumulated in an angle of the mine. Pupa in a white cocoon that is free from frass.

Lithocolletis strigulatella; some authors (including Frankenhuyzen & Freriks, 1976) used the name Ph. rajella for the present-day strigulatella.

notes

The statement in Emmet ao (1985a) that the mine were upper-surface was a mistake (Emmmet, 1994a).
