Scrobipalpa salinella (Zeller, 1847)
[Lepidoptera: Gelechiidae]

Sea-aster Groundling


Gelechia salinella Zeller, 1847. Isis: 853.
Scrobipalpa salinella
(Zeller, 1847).


Leaf-miner: Long, extremely narrow lower- or upper-surface corridor, with a black or brown central frass line. After a while this primary mine is vacated, and the larva starts making shorter, much broader, full depth blotch mines. In the end the larva lives free among spun leaves (Bladmineerders van Europa).

The mine is also 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).

The larvae can live on plants on the lowest parts of saltings, which are frequently immersed by the tide (UKMoths).

Dirty yellow with a red length line; head light brown; pronotum, anal shield and thoracic feet black (Bladmineerders van Europa).

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.

Comments: According to the literature also on Aster tripolium and Suaeda maritima, but probably this concerns occasional observations or confusion with the mines of Bucculatrix maritima (Bland, 2002a; Jansen, in litt.)

The list of hostplants presented by Elsner et al. (1999a), including Atriplex, Spergularia media and even Ferula is bizarre (Bladmineerders van Europa).

Time of year - larvae: May (UKMoths).

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

Distribution in Great Britain & Ireland: Found on saltings in England and Wales where its foodplants grow (UKMoths) including Dorset, East Kent, East Suffolk, Glamorgan, Isle of Wight, North Lincolnshire, South Essex, South Hampshire and West Sussex (NBN Atlas).

It is regarded as a local and difficult-to-record species (MBGBI 4-2), and can probably be most easily found by searching for larvae from late April to early June (UKMoths).

Distribution elsewhere: Widespread in continental Europe including Albania, Austria, Balearic Is., Belgium, Bulgaria, Corsica, Croatia, Czech Republic, Danish mainland, Finland, French mainland, Germany, Greek mainland, Hungary, Italian mainland, Latvia, Poland, Portuguese mainland, Romania, Russia - South, Sardinia, Sicily, Spanish mainland, Sweden, The Netherlands and Ukraine (Karsholt and van Nieukerken in Fauna Europaea).
