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

1a > 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 plant families, but not yet on Globularia, in Britain. On numerous genera and species of plant families including Globularia elsewhere. Widespread in Britain and continental Europe. Also recorded from the Channel Is.

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

1b > Leaf-miner: The larva makes a large number of untidy full depth mines. The mines contain hardly or no frass. The opening made by the larva in the underside of the leaf is irregular roundish, sometimes more of a slit, large in proportion to the size of the mine, and usually positioned at the side of the mine. The larva mines until just before the pupation, that takes place externally.

On Centaurea, but not yet on Globularia, in Britain and Centaurea, Cirsium and Globularia elsewhere. Widespread but scarce in southern England from Wilts to Kent. Widespread in continental Europe.

Jordanita globulariae (Hübner, 1793) [Lepidoptera: Zygaenidae].
