The larvae of a number of species of Chironomidae
(non-biting midges) live in tunnels in decaying leaf sheaths under
water. Their tunnels are open at both ends, and the larvae feed
on particles they obtain from a water current they create in the
tunnels. They do not feed on tissues of their 'hostplant' and therefore
are not strictly miners (Bladmineerders van Europa).
Larva: The larvae of flies are leg-less maggots without a head capsule (see examples). They never have thoracic or abdominal legs. They do not have chewing mouthparts, although they do have a characteristic cephalo-pharyngeal skeleton (see examples), usually visible internally through the body wall.
Puparium: The puparia of flies are formed within the hardened last larval skin or puparium and as a result sheaths enclosing head appendages, wings and legs are not visible externally (see examples).
Cranston in Chandler, 1978
(1978) did not indicate whether his host records were British or
Foreign and are therefore tentatively included under 'Hosts in Britain'
and 'Hosts elsewhere', as is the record by Pitkin & Plant, which was previously assumed to be British.
of year - mines: Currently unknown.
of year - adults: Currently unknown.
