Leaf-miner: Rather small, untidy, full depth, often branched corridor, often
close to the leaf margin. Sides irregularly eaten out. Frass in
a greyish-green central line that is interrupted from time to time,
sometimes partly in strings. In times of rain the frass may run
out and appear greenish. Usually several mines in a leaf (Bladmineeders van Europa).
Larva: The larvae of beetles have a head capsule and chewing mouthparts with opposable mandibles and lack abdominal legs (see examples).
The larva is rather shapeless, with a well-sclerotised head and no feet. The body is whitish; head greyish brown with Y-shaped lighter marking. Pronotum with a pair of brownish shields. The mandibles have two teeth (Bladmineeders van Europa).
Pupa: The pupae of beetles have visible head appendages, wings and legs which lie in sheaths (see examples).
Comments:
Ceutorhynchus insularis is a red data book species, which is unique to St Kilda within the British Isles. Prior to its rediscovery in 2004, the only previously published finding was from 1931. The food plant is common scurvy-grass (Cochlearia officinalis), the only wild crucifer recorded on St Kilda. A population regarded as a different variety of the same species occurs on islands off the South coast of Iceland. C. insularis is related to the common cabbage leaf weevil, C.minutus (= contractus), which is found on mainland Britain and in Europe. It is similar to a variety of C.minutus, which is found on Lundy Island in the Bristol Channel. (British
leafminers).
Alyssum saxatile is treated
as Aurinia saxatile (Golden
Alison) and Arabis arenosa is treated as Arabidopsis
arenosa (Sand Rock-cress); Arabis
glabra is treated as Turritis
glabra (Tower Mustard) and Thlaspi
perfoliatum is treated as Microthlaspi perfoliatum (Perfoliate
Penny-cress) by Stace (2010).
The
Checklist of Beetles of the British Isles (2008 ediiton) includes
Ceutorhynchus minutus (Reich, 1797) non (Drury, 1773) as
a junior synonym of Ceutorhynchus contractus (Marsham, 1802).
