Coleophora conyzae Zeller, 1868
[Lepidoptera: Coleophoridae]

Spikenard Case-bearer


Coleophora conyzae Zeller, 1868. Verh. zool-bot. Ges. Wien. 5: 623.


Leaf-miner and case-bearer: The larva makes at least two cases and leaves the empty case by the cut out leaf section. The early cases are compressed with keels, dorsally and laterally. Later cases are more tubular and hairy (from the hairy leaves, used to make the case) (British leafminers).

Larva in a spathulate leaf case. It is 10-12 mm long, straght, brown, tubular, patently hairy (depending on the hostplant), bivalved. The mouth angle is rather variable, usually around 45°. An unusual character of this species is that after each moult the larva makes a new case; the old, vacated case is left at the place where the new one is made, at the leaf margin (Bladmineerders van Europa).

The case is illustrated in UKMoths.

Larva: The larvae of moths have a head capsule and chewing mouthparts with opposable mandibles (see video of a gracillarid larva feeding), six thoracic legs and abdominal legs (see examples).

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

Adult: The adult is illustrated in UKMoths. The male and female genitalia are illustrated by the Lepidoptera Dissection Group.

Time of year - larvae: September - May (British leafminers).

Time of year - adults: June and July (UKMoths).

Distribution in Great Britain & Ireland: Mainly distributed in southern England and Wales (UKMoths) including Bedfordshire, East Gloucestershire, East Kent, East Suffolk, Glamorgan, North Somerset, Pembrokeshire, South Devon, South Essex, South Hampshire, South Wiltshire, Surrey and West Kent (NBN Atlas). A colony has also been located in York, so it may occur elsewhere (UKMoths).

Distribution elsewhere: Widespread in continental Europe including Albania, Austria, Corsica, Crete, Croatia, Czech Republic, Estonia, Finland, French mainland, Greek mainland, Hungary, Italian mainland, Latvia, Malta, North Aegean Is., Poland, Portuguese mainland, Romania, Sardinia, Sicily, Slovakia, Spanish mainland, Sweden, Switzerland and The Netherlands (Karsholt and van Nieukerken in Fauna Europaea).
