There are probably at least two generations per year.

The larvae feed on Acer mono and Acer crataegifolium. They mine the leaves of their host plant. The mine consists of a linear-blotch, starting as a thin and contorted gallery, gradually becoming broader towards two thirds of the length of the mine. Then it widens into a large blotch. The frass in first part of the mine is broken-linear, sometimes deposited as a minute mass within each leaf-areola. Later, the frass is neatly coiled and occupying almost the whole width of the mine. At the end, the frass is dispersed and found in a wide line occupying about half the width of the mine. In the blotchy part of mine, the frass is scattered irregularly in the centre.
