Egg: Underside of leaf

Mine: July-October

Notes: Makes an irregular blotch mine. The initiasl frass-filled gallery is very contorted. It then makes an irregular gallery with clear margins and linear frass. Finally there is a small clear blotch, with the frass in a heap at the mouth of the gallery. The larva feeds with its ventral surface uppermost. Tends to be found in Southern coastal regions. Two mines are shown above.
