Exoteleia dodecella (Linnaeus, 1758)

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

The larva enters the needle at about three quarter of its length, at the flat side; the opening is closed with silk (picture above). From here the larve mines upwards (rarely also a small distance downwards).The larva lives in a spacious larval chamber in the lowest part of the mine, lined with stripes of dense spinning. The frass is accumulated in the apical part of the mine. Sometimes one, more rarely two, openings are made to eject part of the frass; these openings too are closed with silk, and are difficult to find. No egg shell is visible at the start of the mine. The larva hibernates in the mine; in the following spring it feeds on the shoots and in spun needles (Hering, 1957a). Pupation external, in a bud (Freeman, 1960a).
