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.

host plants

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 confirmation.

phenology

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

BENELUX

BE not recorded (Fauna Europaea, 2009).

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

LUX not recorded (Fauna Europaea, 2009).

distribution within Europe

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

larva

Dark yellow; the larva lacks a field of spinules at he rear of the pronotum, and on the mesosternum spinulation does not only occur on the rudiment of the foot, but also in two field obliquely in front. See Gustafsson & van Nieukerken (1990a) for a description.
