mine

Oviposition on the tip of the flat side of the needle; the egg is oval, smooth, with a characteristic longitudinal keel. From here the mine descends, full depth, towards the base of the needle. The space behind the larva is completely filled with granular frass. The larval chamber is so transparant that the larve inside is easily visible. The larve vacates the mine prior to pupation by a round opening near the end of the mine.
