Locally common to very common, mainly observed in Flanders.
Head brownish; forewing ground colour brown, pattern consisting of a short white basal line, four costal and four (sometimes a fifth very small) dorsal white striae, the first and second pair usually merged to form a transversal band.
A whitish tentiform mine on the underside of a leaf, one large and many small longitudinal folds. When the mine is constructed in a small leaf, it might occupy the entire leaf surface; in such cases the leaf is very much contorted. The black frass is concentrated in one side of the mine.

A tough olive-green cocoon inside the mine, later turning into light brown.
In the autum, the mined leaf drops down to the ground where it witters completely during the winter and only the tough cocoon remains to protect the pupa inside.
Two generations a year: May and August.
The larva lives on Lonicera periclymenum, L. xylosteum and on Symphoricarpos albus. It has also been recorded from other species of Lonicera, but most of these do not occur in Belgium.
Parks and gardens where Lonicera or Symphoricarpos albus are planted as ornamental plants.
