Exoteleia dodecella

Exoteleia dodecella (Linnaeus, 1758)

pine groundling

Exoteleia dodecella mine

Pinus sylvestris, Hilversum (winter): basal side of the mine, with the opening, closed with silk, by which the larva has entered (tip of the needle at left).

mine

!-5 Eggs are deposited near the very base of a needle; the empty vacated eggs shells later soon drop off. The larvae emerge around end June. The young larva enters a needle in the lower third of the length, at the flat side, then makes a narrow gallery, 1-5 cm long, more or less running upwards; the gallery is stuffed with frass for most of its length, and has 1-3 openings, that are closed with silk. End of September the youth mine is left, and the larva starts making a large blotch mine in the apical part of the needle; most frass is ejected from this mine. In this mine the larva hibernates. In early spring a third mine is made, in the same needle or in another one. Around April the larva spins one or a group of buds, and enters one of them. Also the pupation takes place inside this bud (Lemarie).
