mine

Oviposition usually near the leaf tip. Oviposition scar mostly an elongated lacerated hole. Very long corridor (up to 10 cm), upper-surface, strongly widening towards the end. Primary and secondary feeding lines apparent in fresh mines. Pupation outside the mine, exit slit in upper epidermis. Often several mines in a leaf. Mines invariably in leaves that are not yet fully developed, and are strongly malformed as a result.

host plants

Cannabaceae, monophagous

Celtis australis.

phenology

Larvae in May – October (Hering, 1957a, Nowakowski, 1960a); hibernation as puparium.

BENELUX

Not known from the Benelux countries (Fauna Europaea, 2008).

distribution within Europe

From Spain to Thrace (Fauna Europaea, 2007).

larva

Described by Nowakowski (1960a). Mandibles not alternating, with two teeth. Front spiraculum with 5, rear spiraculum with 3 papillae.

The larva description by Beri (1971c), based on material from Rubus niveus, cannot be taken seriously.

puparium

1.8 mm in length, rusty brown, smooth and shining, with deep furrows between the segments (Nowakowski, 1960a).

synonyms

Agromyza celtidis Nowakowski, 1960.

notes

Mines not only in young leaves, but also a strong preference for young trees and suckers (Nowakowski, 1960a). Frequently in urban ornamental planting (Süss, 1992a).
