Bohemannia pulverosella: exit slit of mine

exit slit

mine

Egg either at upperside or underside of the leaf, close to the leaf margin. The mine begins as a narrow corridor which is strongly contorted, unless it lies close to the leaf margin. The corridor abruptly widens into an elongate blotch, that often runs over the initial corridor. The frass is brown; it almost fills the initial corridor; in the blotch it is concentrated in its first section. Pupation external; exit slit invariably in the lower epidermis (In Ectoedemia atricollis, of which the mine bears some resemblance to the one of pulverosella the exit slit is in the upper epidermis; moreover, atricollis is much later in the year.)

hostplants

Rosaceae, monophagous

Malus domestica, x purpurea, sylvestris.

In the older literature also mentioned from Prunus domestica and Pyrus communis; as fas is known this has not been confirmed by breeding.
