Plant Parasites of Europe

leafminers, galls and fungi

Stephensia abbreviatella

Stephensia abbreviatella (Stainton, 1851)

Stephensia abbreviatella mine

from Klimesch (1939b)

mine

The first mine begins in a low leaf, with a short, lower-surface corridor that quickly widens into a full depth, transparent blotch. Some silk is deposited in the mine. Its underside inflates strongly, while the upper side develops folds, causing a real tentiform mine to develop. Before the the onset of hibernation the larva makes a new mine, consisting of a fairly broad corridor along the midrib, lined with much silk. In spring the leaf of the overwintering mine has almost completely decayed. Until the larva is full grown it makes several new mines. On leaving a mine it makes an exit slit in the upper epidermis, near the leaf base. The new mines begin with a short, broad, corridor in the sponge parenchyma, ant it is here that the frass is deposited in a compact mass. Pupation in the soil.

hostplants

Boraginaceae, narrowly monophagous

Myosotis sylvatica.

An attempt to transfer the larva to Myosotis arvensis failed (Buhr, 1956a).

phenology

Larvae from early-September till May of the following year (Klimesch, 1939b).

BENELUX

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

distribution within Europe

From Germany and Poland to France, Austria and Thrace (Buhr, 1956a; Fauna Europaea, 2009).
