Scrobipalpa samadensis (Pfaffenzeller, 1870)
[Lepidoptera: Gelechiidae]

Buck's-horn Groundling


Gelechia samadensis Pfaffenzeller, 1870. Stett. ent. Ztg. 31: 321.
Gelechia plantaginella
Stainton, 1883. Ent. mon. Mag. 19: 253.
Scrobipalpa samadensis
(Pfaffenzeller, 1870).


Leaf-miner: Feeding is in leaf blotches, spun shoots and roots. Wilting greyish leaves, or frass in the crown of the plant may indicate a larva in the roots (UKMoths).

Young larver make a short, very narrow gallery in the young leaves. Later they bore in the rhizome ( 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).

Body yellowish white with several salmon length lines; head, prothoracic plate and thoracic legs blackish brown; anal plate light brown (Bland et al., 2002a) (Bladmineerders van Europa).

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

Pupae are found in the plant root from May to August (UKMoths). See Patocka and Turcáni (2005a) (Bladmineerders van Europa).

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

Hosts elsewhere:

Plantago maritima Sea Plantain British Wild Flowers by John Somerville et al. Bladmineerders van Europa

Time of year - larvae: Larvae are found from April to August. It is uncertain if there is more than one generation, or just a single protracted one (UKMoths).

Time of year - adults: June to September (UKMoths).

Distribution in Great Britain & Ireland: Widespread, and often common, on saltings and hard-rock coasts of Britain (UKMoths) including Cheviotland, East Norfolk (VC27), East Suffolk (VC25), Elgin, Glamorganshire (VC41), North Aberdeen and Northumberland South (NBN Gateway), the Channel Is. (Karsholt and van Nieukerken in Fauna Europaea).

Also recorded in the Republic of Ireland and Northern Ireland (Karsholt and van Nieukerken in Fauna Europaea). See also Ireland's NBDC interactive map.
