Scrobipalpa costella (Humphreys & Westwood, 1845)

winter groundling

Scrobipalpa costella mine

Solanum dulcamara, Cadzand

Scrobipalpa costella mine

same mine, detail (the strange colours resulted from movements of the larva during the exposure)

mine

Young larvae bore in the midrib that turns somewhat pale and translucent; from here they make rather small, brownish, wrinkled, not very transparent blotches. Later they can make blotches that extend further from the midrib, but often that rather soon take on a boring habit, or start to live freely upon the plant. Pupation external.

host plants

Solanaceae, narrowly monophagous

Solanum dulcamara.

Observations of S. tuberosum Elsner ao, 1999a) are considered doubtful by Bland ao (2002a). However, observations, albeit occasionally, on Atropa bella-donna and Solanum melongena by Beavan & Heckford demonstrate that the species is not absolutely confined to bittersweet.

phenology

Univoltine, larvae from mid-September till May, June (Jansen, 1999a); but see also Harvey (2004a).

BENELUX

BE recorded (Phegea, 2010).

NE recorded (Kuchlein & de Vos, 1999a; Microlepidoptera.nl, 2010).

LUX not recorded (Fauna Europaea, 2010).

distribution within Europe

From Denmark to the Pyrenees, and from Ireland to Germany (Fauna Europaea, 2010).

larva

synonyms

Gnorimoschema costellum.

notes

In the Netherlands seen mostly where the host plant grows close to the sea coast (Jansen, 1999a), but recently also observations are made in the interior (ten Holt & Kuchlein, 2003a). Also the distribution in Britain (Bland ao, 2002a) shows many inland observations.
