Agromyza lathyri Hendel, 1923

12638

Pisum sativum, Castricum: part of the mine; also visible is a part of the initial corridor and, vaguely, a larva

mine

The mine starts as a superficial lower-surface corridor. After its first moult the larva starts making a blotch, often close to the base of the leaflet. The blotch in principle is lower-surface, but may be interparenchymatous for some part. Moreover, in places the larva feeds from the palissade parenchyma. Seen from above the leaf appears mottled. The overall result is that the mine, despite its considerable size, is hard to find. The easiest way is to hold the leaves against the light: the large larvae than are conspicuous. Frass in coarse grains, both in the corridor and in the blotch; in the corridor they are widely spaced. Pupation outside the mine.
