Cosmopterix pulchrimella

mine with pupa


Oval, whitish, ribbed egg shell generally at the underside of the leaf. The mine begins as a short irregular corridor, usually following the midrib, widening into an irregular blotch. Some silk is deposited in the mine, causing it to contract a bit. Most frass is ejected through an opening near the begin of the mine; some is trapped in spinning under the leaf. The larva often moves to a new mine. Pupation within the mine (Koster & Sinev, 2003a), in a folded leaf margin or in a leaf fold.


Urticaceae, monophagous

Parietaria judaica, officinalis, pensylvanica; Pilea pumila.


Several overlapping generations.


First observation in the Benelux in 2017 (Belgium, prov. West Flanders, Koksijde; Chris Steeman in iitt.).
