Plant Parasites of Europe

leafminers, galls and fungi

Monochroa tetragonella

Monochroa tetragonella (Stainton, 1885)

common plain neb


In autumn the larva mines a number of the upper leaves completely out, migrating through the stem from one leaf to another. The mined leaves contain much dense, black frass. After the hibernation the larve lives as a stem borer. Infested plant parts turn pale and wilt.

host plants

Primulaceae, monophagous

Glaux maritima.


Larvae from September till April.


BE recorded (Phegea, 2011).

NE recorded (Kuchlein & de Vos, 1999a;, 2011).

LUX not recorded (Fauna Europaea, 2011).

distribution within Europe

From Fennoscandia and North Russia to Belgium and Germany, and from Britain to South Russia (Fauna Europaea, 2011).


Body crimson reddish, with minute black pinacula; head ochreous-yellow; prothoracic plate dark brown (Bland ao).


Aristotelia, Monochroa, Xystophora gudmanni Larsen, 1927 (?)


The synonymy is probable (on the basis of the descriptions of the biology), but I have not found a definite confirmation in the literature. Hering (1957a) cites Rebel as the author of gudmanni, but this may be due to confusion with Depressaria gudmanni, a very different species.
