Newly discovered in Belgium in 2013, but rapidly spread all over Flanders; currently (2019) only recorded from the provinces HA and LG in Wallonia.
Head white; forewing ground colour silvery white, sometimes darkened with very light ochreous scales; the dorsal half of the apical area often darkened with greyish brown scales; five ochreous to brown costal striae of which the second one is prolonged to the dorsum, thus forming a narrow transversal band; a black spot in the apical area from which three dark brown hooks depart into the cilia.
No real cocoon, but a flimsy spinning which is not pure white as in most other Phyllocnistis species, but greenish or yellowish.
The eggs are oviposited mainly on the upperside of the leaf.
Pupation under a flimsy membrane at the end of the corridor at a margin of a leaf, which is turned over the membrane.
The adults are active at dusk. Probably, the species hibernates in the adult stage.
Not much is known about the situation in Belgium; but probably moths can be found from late November, hibernating till April–May.
