Ectoedemia klimeschi (Skala, 1933)

mine

The egg is deposited on the petiole. Here lives the larva initially as a borer, causing the petiole to swell gall-like somewhat. After the last moult the larva enters the leaf and makes a bloth there. Mostly the blotch is not positioned between two thick veins, but lies at either side of a thick vein, or even the midrib. The larva mainly feeds and night, and retreats into the petiole at daytime. This forces the frass in two broad lines, parallel to the sides. Pupation external.

host plants

Salicaceae, monophagous

Populus alba.

On saplings, and on large, lobed, leaves of young branches on trees; generally not in green islands (van Nieukerken, 1985a).

phenology

Larvae probably in the petioles already in summer; leafmining larvae in September – November (van Nieukerken, 1985a).

BENELUX

Not known from the Benelux countries (Fauna Europaea, 2009).

distribution within Europe

From Germany, Poland, and the Baltic States to Italy and Greece (Fauna Europaea, 2009).
