35.139 Caryocolum huebneri (Haworth, 1827)

Status and Distribution

Extinct, with the last probable records during the 19th Century.

The former distribution of this species is imperfectly known due to confusion (covering both nomenclature and misidentification) with Caryocolum kroesmanniella. Records from Bedfordshire, Berkshire, Kent, Surrey and Sussex are considered (by Parsons, M., 1995) to be the most likely to be authentic and it certainly occured in England as the 'type' locality is there.

    Habitat

    Appears to be mainly associated with woodland.

    Finding the Moth

    Larva: feeds within spun shoots and, in Eurpoe, is reported to feed within seed capsules in June.

    Adult: has been found on a tree trunk and comes to light (the latter reported in Europe).

    Similar Species

    In view of the status of this species in Britain and its confusion with C. kroesmanniella no more than a single voucher specimen should be retained for examination if this species is suspected.

    C. kroesmanniella is larger (wingspan 12-15mm as opposed to 9-12mm in C. huebneri) and has no connecting bar between the costa and the plical spot. Best separated by examination of the genitalia.

    Single brooded, but with details of specific dates in Britain currently not yet researched, the figures quoted are taken from European literature so should be taken only as a rough guide.
