details

Acalyptris minimella mines

Pistacia lenticus, Rhodes; from Klimesch (1978b)

mine

Egg on leaf upperside, usually close to a vein. The mine begins as an extremely narrow, rather straight corridor, filled with frass, often following the margin of the leaflet or the midrib. Well over half of the lenght of the mine the corridor gradually widens and begins to zigzag more or less; frass here coiled or in discrete grains, about 2/3 of the corridor width. Pupation outside the mine, exit slit in upper epidermis.

Leaflets with completed mines usually discolouring and easily falling off (van Nieukerken, 2007a).
