SCANDIX. Shepherd's-needle. [Apiaceae]


One species of Scandix is recorded in Britain.

Only one British miner is recorded on Scandix.

A key to the European miners recorded on Scandix is provided in Bladmineerders van Europa.



Key for the identification of the known mines of British
insects (Diptera and non-Diptera) recorded on Scandix


1 > Leaf-miner: In the first instar the larva mines the leaves, forming short, irregular, blotch-like mines, but in later instars it lives externally, feeding in spun leaves and often twisting those of tender shoots. Larval head light-brown or yellowish brown, edged with black postero-laterally, ocellar area blackish; prothoracic plate black edged with whitish anteriorly; abdomen dull dark green; pinacula distinct, black, sometimes brownish but with black bases to setae; anal plate large, black (Bradley et al., 1973). Small, full depth mine without a definite shape; little frass. Some silk is deposited in the mine. The larva soon leaves the mine and continues feeding among spun leaves.

Polyphagous. On numerous genera and species of several plant families, but not yet on Scandix, in Britain and elsewhere. Widespread in Britain and continental Europe. Also recorded from the Channel Is.

Cnephasia incertana (Treitschke, 1835) [Lepidoptera: Tortricidae].

ation all frass is deposited in one big mass. Puparium within the mine, where it also passes the winter.

On Carex and Scirpus, but not yet on Schoenoplectus, in Britain and Scirpus and Scheonoplectus in continental Europe. Probably widespread in Britain. Widespread in continental Europe. Also recorded in Canada.

Cerodontha scirpi (Karl, 1926) [Diptera: Agromyzidae].

1c > Leaf-miner: Mines and larvae indistinguishable from C. morosa. Mine relatively short and broad, not extending into leaf base. Pupation in the mine (Spencer, 1976: 219).

On Carex and Scirpus, but not yet on Schoenoplectus, in Britain and elsewhere. Only recorded from Cambridge, Suffolk and Warwick in Britain. Widespread in continental Europe.

Cerodontha suturalis (Hendel, 1931) [Diptera: Agromyzidae].
