Stigmella desperatella (Frey, 1856)
scarce apple pigmy
Malus domestica, Austria, (Kärnten) Pörtschach, 5 km W Völkermark;leg JJ Boomsma & EJ van Nieukerken
Egg either at upper side or underside of the leaf. The mine begins as a narrow gallery, often following a vein or the leaf margin. Later sections of the corridor are much wider and contorted, mostly forming a secondary blotch. Frass in an extremely narrow central line, sometimes a bit broader towards then end of the mine. Often several mines in a leaf.
woody Rosaceae, oligophagous
Larvae in late summer (Emmet, 1983a).
Not known from the Benelux countries (Fauna Europaea, 2009).
distribution within Europe
From Estonia to the Pyrenees, Italy, and Bulgaria, and from Britain to the Ukraine (Fauna Europaea, 2009).
The larva is green; this distinguishes the species from St. malella, that also lives on apple, but has a yellow larva.
Also St. magdalenae may be found op apple, and this species has green larvae. The only reliable difference is that the larva of magdalenae has a field of fine spinules on abdomen 9, that is lacking in desperatella (Emmet, 1983a; Gustafsson & van Nieukerken, 1990a).
Nepticula desperatella; N. pyricola Wocke, 1877.
