Tebenna micalis (Mann, 1857)

vagrant metal-mark

mine

A sizable blotch with an ample quantity of frass. The larva may leave its mine and restart elsewhere. Older larvae often live free in a web under the leaf.

This description, based on Hering (1927a, 1957a), and probably stemming from his experience on the Canary Island is not supported by later authors, who only write about free-living larvae. Also the description by Pelham-Clinton (1985a) and pictures on the internet rather suggest lower-surface window feeding.

hostplants

Asteraceae, oligophagous

Anaphalis triplinervis; Arctium lappa, minus; Carduus baeocephalus, crispus; Carlina acanthifolia, acaulis, vulgaris; Cirsium; Cynara scolymus; Dittrichia viscosa; Echinops; Helichrysum foetidum, italicum subsp. picardii, melaleucum; Inula conyzae, helenium, salicinal Laphangium luteoalbum luteoalbum; Pulicaria arabiva subsp. hispanica, dysenterica, vulgaris; Vogtia annua.

A reference to Eryngium spinalba (Apiaceae) is dubious.

BENELUX

Not known from the Benelux countries (Fauna Europaea, 2009).

synonyms

Choreutis micalis; Tebenna bjerkandrella of the English authors until the publication by Heckford (1990a). Possibly also the references to bjerkandrella by Kvičala (1938a) and Skala & Zavřel (1945a) relate to micalis.
