Stigmella poterii (Stainton, 1857)

downland pigmy

Stigmella poterii mine

Potentilla sp.; coll. JC Koster

mine

Egg generally at the upperside of the leaf, on a vein. The mine is a short corridor, no longer than 3 cm. Its first part is narrow and tends to follow a vein. The second part is rather tortuous and considerably widened, and often forms a secondary blotch. Generally only one mine in a leaf. Mines cannot reliably been distinguished from those of St. anomalella and St. centifoliella.

hostplants

herbaceous Rosaceae, oligophagous

Argentina anserina; Potentilla erecta, recta, tabernaemontani; Comarum palustre; Rubus arcticus, chamaemorus, saxatilis; Sanguisorba minor, officinalis.

A & Z Laštuvka (1997a) also mention Filipendula ulmaria; this needs further confimation.

phenology

In central Europe bivoltine (Johansson ao, 1990a).

BE not recorded (Fauna Europaea, 2009).

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

From Fennoscandia to the Pyrenees and Italy, and from Ireland to the Ukraine (Fauna Europaea, 2009).
