Ulmus spec., Belgium, prov. Namur, Couvin, Zône Industriel le long de l’Eau Blanche © Stéphane Claerebout; det. Erik van Nieukerken

mine

Very compact mine; a strongly contorted corridor in “intestine-like”, zigzagging loops; only the very last part of the corridor is free. Frass in the first and in the final part of the mine black, warm brown and coiled in the central section, and, except for the last section, occupying the entire width of the gallery. Fresh mines have a striking red brown colour. In the two mines that I know th mine was placed at the lower side in one, upper side, on a vein, in the second.

host plants

Ulmaceae, monophagous

Ulmus minor, plotii.

BENELUX

BE Found in 2014 by Stéphane Claerebout; pictures above.

NE not recorded (Fauna Europaaa, 2009); see also the note below.

LUX not recorded (Fauna Europaea, 2008).

distribution within Europe

Central and southern Europe, including the UK, but excluding the Iberian Peninsula (Fauna Europaea, 2008).

larva

Bright green (Emmet, 1983a).

synonyms

Nepticula viscerella.

notes

Strongly wound mines of Stigmella lemniscella can resemble deceivingly those of viscerella. Such mines for some time have led to the supposition that viscerella did occur in the Netherlands, until DNA-research disproved the identification. Galleries of viscerella start by making a number of zigzag loops; moreover the larvae are green, not yellow.
