Plant Parasites of Europe

leafminers, galls and fungi

Elachista humilis

Elachista humilis Zeller, 1850

obscure dwarf


In spring a short corridor is made that is almost stuffed with frass. After hibernation this mine is vacated, and the larva then makes a number of elongated blotches, all descending from the leaf tip. These latter mines are whitish, with irregularly scattered frass.

host plants

Cyperaceae, Poaceae, narrowly polyphagous

Agrostis; Anthoxanthum odoratum; Carex; Deschampsia cespitosa; Festuca; Holcus lanatus; Phalaroides arundinacea; Poa pratensis.

Deschampsia cespitosa is the main hostplant; the other hostplants on the list are not all equally trustworthy because of possible confusion with Elachista canapennella (Traugott-Olsen & Nielsen, 1977a).


Larvae from autumn till spring (Bland, 1996a; Traugott-Olsen & ]Nielsen, 1977a).


BE recorded (Phegea, 2009).

NE recorded (Kuchlein & de Vos, 1999a;, 2009).

LUX not recorded (Fauna Europaea, 2009).

distribution within Europe

Almost entire Europe, except the Iberian and the Balkan Peninsula (Fauna Europaea, 2009).


Lemon yellow, dull yellowish to greenish yellow with a lighter mid-dorsal line; head light brown. According to Hering (1957a) the prothoracic plate has a darker centre.


Described by Patočka & Turčáni (2005a).


Elachista airae Stainton, 1858; E. perplexella Stainton, 1858.
