Ocnerostoma piniariella Zeller, 1847

white pine ermine

Ocnerostoma piniariella egg

Pinus sylvestris, Gortelsche Berg: egg on the tip of a needle

mine

The mine begins in the tip of a needle, and descends to about three quarter of its length. With exception of the larval chamber the entire mine is filled with frass, giving the needle a vinous colour. The mine is so transparant the the larva is visible in its chamber (Hering, 1957a). The full grown larva leaves the mine by making an opening, then forms an elongate cocoon out of silk between a few spun needles (Koch, 1932a; Freeman, 1960a).

hostplants

Pinaceae, monophagous

Pinus cembra, mugo, sylvestris.

According to Hering (1957a) the species also lives on Juniperus albeit rarely. In the light of the strongly different leaf morphology this seems improbable. Also references to Abies alba and Picea abies seem doubtful.
