Delia brunnescens (Zetterstedt, 1845)

Initially narrow, but gradually widening, full depth corridors. They start from the leaf base en cross themselves regularly. The larva migrates from one leaf to the other by way of the petioles and the stem. Pupation outside the mine.

Caryophyllaceae, oligophagous

Dianthus barbatus, chinensis, caryophyllus; Silene, flos-cuculi, vulgaris.

phenology

Larvae in September-April (Hering, 1957a).

BE recorded (Gosseries & Ackland, 1991a).

NE recorded (de Meijere, 1939a).

LUX not recorded (Fauna Europaea, 2007).

synonyms

Phorbia, Hylemyia, Chortophila brunnescens. Chandler (1998a) considers brunnescens a junior synonym of Delia cardui (Meigen, 1826), but this view is not shared by most modern authors. If, and how, the biology of the two species differs is unclear.
