35.015 Nothris verbascella (Hübner, 1813)

Status and Distribution

Formerly found at two locations in Norfolk and one in Suffolk and was last seen in West Norfolk in 1971. Searches at this last location from the late 1980s onwards, where the foodplant is still present, have failed to relocate the moth and it is now considered extinct in the British Isles. A record from Monk Haven, Pembrokeshire has not been possible to confirm and is thought to have been entered in error but the food-plant does occur in that county.

    Foodplant and Larval Feeding Signs

    Verbascum pulverulentum (hoary mullein), see plant distribution map. In Europe reported from Verbascum densiflorum (dense-flowered mullein), V. phlomoides (orange mullein) and V. thapsus (great mullein).

    Larva can be present throughout the year, initially gregariously on undeveloped leaves in the centre of the plant. In the spring newly emerged larvae can be found feeding on younger leaves or boring into stalks or stems, while the over-wintered larvae feed under the larger lower leaves in a silken web.

    Habitat

    Disturbed ground such as gravel-pits and quarries (the plants original 'natural' habitat is on coastal shingle).

    Finding the Moth

    Searches of sites where the foodplant still occurs in any abundance would be worthwhile at any time of year for the larvae.

    Similar Species

    A distinctive pale buff moth with a single prominent black spot on the forewing at two-thirds. Not likely to be confused with any other species.

    Larval Occurrence

    Flight Period

    Flight Period

    Possibly double-brooded with adults emerging from May to September and with peaks in June and September. The September moths are smaller than those in June. There is insufficient data on adults observed in the wild as most records relate to bred specimens.
