Scrobipalpa acuminatella (Sircom, 1850)
[Lepidoptera: Gelechiidae]

Pointed Groundling


Gelechia acuminatella Sircom, 1850. Zoologist App.: 72.
Scrobipalpa acuminatella
(Sircom, 1850).


Leaf-miner: The mine is brownish and extends along the midrib, sometimes branching (British leafminers).

Oviposition on top of the midrib. Immediately after emergence the larva gnaws a cavity in the midrib, and from there an irregular blotch is made adjacent to the midrib. The larva continues living in the midrib that is gradully hollowed out, making from there broad, brownish, full depth excursions in the blade. The mine contains much frass; most of it is concentrated in the area immediately bordering the midrib. Older, no longer occupied parts of the mine often split open. Mines mainly on the lower leaves. The slender larvae move surprisingly fast upon disturbance; when they rest (in daytime) they lie lengthwise in the hollowed midrib. Pupation outside the mine (Bladmineerders van Europa).

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).

The larva is illustrated in Bladmineerders van Europa.

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

On the ground in the leaf litter (British leafminers).

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

Comments: Records from Carlina vulgaris and Tussilago farfara are probably incidental. Reports from Cnicus benedictus and Onopordum are dubious. Records from Centaurea scabiosa and Serratula tinctoria probably refer to Scrobipalpa pauperella (Sattler, 1986a, Jansen, 1999a; Bland at al., 2002a). Seen in this light also the references to Artemisia campestris and Tanacetum vulgare (Elsner at al., 1999a) not very probable (Bladmineerders van Europa).

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

Time of year - adults: Generally there are two generations, with adults on the wing in April to June and again in July to September (UKMoths).

Distribution in Great Britain & Ireland: Widely distributed across much of the British Isles, this species occupies rough and open ground where thistles abound (UKMoths) including Bedfordshire, Berkshire, Caernarvonshire, Cambridgeshire, Denbighshire, East Gloucestershire, East Kent, East Norfolk, East Suffolk, Easterness, Forfar, Glamorgan, Herefordshire, Hertfordshire, Huntingdonshire, Kincardineshire, Middlesex, North Aberdeen, North Ebudes, North Essex, North Hampshire, North Somerset, North Wiltshire, South Northumberland, South Aberdeen, South Lancaster, South Somerset, South Wiltshire, Stafford, Surrey, Warwickshire, West Gloucestershire, West Norfolk, West Suffolk and Worcestershire (NBN Atlas).
