GLYCINE. Soya-bean. [Fabaceae]

Only one species of Glycine is recorded in Britain, the introduced Soya-bean (G. max).

No Diptera miners are recorded on Glycine in Britain.

Elsewhere the agromyzids Chromatomyia horticola, Liriomyza congesta, Liriomyza huidobrensis, Liriomyza sativae and Liriomyza trifolii are recorded mining Glycine.

No non-Diptera miners are recorded on Glycine in Britain.

Elsewhere one British non-Diptera miner is recorded on Glycine (see below).

A key to the European miners, based on characteristics of the mines, immature stages and where relevant the larval cases, recorded on Glycine is provided in Bladmineerders van Europa. This includes Chromatomyia horticola, Liriomyza congesta and Aproaerema anthyllidella but not Liriomyza huidobrensis, Liriomyza sativae or Liriomyza trifolii.

Note: The larvae of mining Coleoptera, Hymenoptera and Lepidoptera may live in a corridor mine, a corridor-blotch mine, a blotch mine, a case, a rolled or folded leaf, a tentiform mine or sandwiched between two more or less circular leaf sections in later instars. Larva may pupate in a silk cocoon. The larva may have at least six legs (although they may be reduced or absent), a head capsule and chewing mouthparts with opposable mandibles (see video of a gracillarid larva feeding). Larvae of Hymenoptera and Lepidoptera usually also have abdominal legs (see examples). Frass, if present, never in two rows. Unless feeding externally from within a case the larva usually vacates the mine by chewing an exit hole. Pupa with visible head appendages, wings and legs which lie in sheaths (see examples).

1 > The first generation initially forms an unmistakable leaf-mine on Anthyllis vulneraria, but the second generation feeds on the flowers. Feeding signs on other plants vary in appearance. Larvae can move between sewn leaves, and more than one larva may be found together (UKMoths). Larvae in a small full depth blotch, often with extensions. Frass concentrated in one corner of the mine. The mining activities may cause the leaf to roll inwards. Older larvae live free among spun leaves, but still they may make then full depth mines by feeding on the leaf tissue from a small opening (Bladmineerders van Europa).
