Monochroa tetragonella (Stainton, 1885)

common plain neb

mine

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.

Primulaceae, monophagous

Glaux maritima.

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

notes

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