A common species throughout Belgium, sometimes causing damage to hedges curling the leaves and turning them brownish.
A whitish silken cocoon on the underside of the leaf.
Most of the time, ten or more eggs are deposited together near the midrib of a leaf. The first instars each construct their initial mine in the same leaf. Later on the leaf starts to contort and the tissue turns brownish. The free living instars leave the mine and spin a downwards rolled leaf in which they still continue feeding together. Pupation individually in a white cocoon which is spun on the underside of a leaf, most of the time dropping to the ground during autumn. The adults are active at dusk and come to light.
The adults fly in two generations a year: from late April towards mid June and again from late June till late August.
The larvae feed on Ligustrum, Fraxinus and Syringa. The species sometimes also mines planted bushes or trees, mainly of the family Caprifoliaceae, but in these cases, the development is not complete.
Parks, gardens, forest edges or clearings, also lonely growing Fraxinus trees.
