Comment: The senior name is Orchestes hortorum (Fabricius, 1792) and will be included as such in the next Coleoptera Checklist (2016) (pers.comm Colin Plant ex Andrew Duff).

Leaf-miner: A gallery along the edge of the leaf leading to a circular blotch, from which a case is cut leaving a round hole (British leafminers, as O. signifer).

Rather short corridor along the leaf margin, widening into a circular blotch that usually is free from the margin. The mature larva makes an excision that includes almost all of the blotch, and thus sandwidched drops to the ground for pupation (Bladmineerders van Europa).

Larva: The larvae of beetles have a head capsule and chewing mouthparts with opposable mandibles and lack abdominal legs (see examples).

The larva is illustrated in (British leafminers, as O. signifer) and Bladmineerders van Europa.

Pupa: The pupae of beetles have visible head appendages, wings and legs which lie in sheaths (see examples).
