Stigmella ulmivora: mine on Ulmus spec.



Egg at the underside of the leaf, generally near a vein. The mine is s slender corridor. Frass in its first part in a narrow central line. The frass pattern in the later segment is very variable: sometimes in a narrow central line, sometimes broadly dispersed or even coiled. Especially in the latter case confusion with St. lemniscella is hard to avoid. The only reliable character that remains then is that the exit slit is in the lower epidermis

host plants

Ulmaceae, monophagous

Ulmus glabra, x hollandica, laevis, minor, pumila.


Two generations, the first one much scarcer than the second (Johansson ea, 1990a).


BE recorded (Phegea, 2009).

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

LUX not recorded (Fauna Europaea, 2009).

distribution within Europe

Europe, except the Balkan Peninsula (Fauna Europaea, 2009).


Blue green (amber in lemmiscella); see Gustafsson & van Nieukerken (1990a) for a description.


Nepticula ulmivora; N. ulmifoliae Hering, 1931; N. ulmicola Hering, 1932; Stigmella ulmicola



Occasionally a larva was seen that for some reason seemingly was unable the create sufficiently space around itself, and could eat only right ahead. Such larvae, probably doomed, are unusually slender, and bear a pernicious resemblance to a Bucculatrix larva. It is imperative then to dissect the larva out of the mine and study it under a microscope.

left a normal larve; the larva at right seems squeezed and is probably moribund
