Stigmella microtheriella parasite

Stigmella microtheriella (Stainton, 1854) nut-tree pigmy Corylus avellana, Amstelveen Carpinus betulus, Germany (Baden-Württemberg), Badenweiler: in this hostplant the mine is much more determined by the venation of the leaf Carpinus betulus, Belgium, prov. Liège, Braives © Jean-Yves Baugnée Corylus avellana, Nieuwendam: also in the very first part of the corridor…

Stigmella carpinella parasite

…filled with frass; in the later part the frass lies in thick lumps. The trajectory of the mine is not angular, neither is it determined by the leaf venation. The discrimination between this mine and the one of Stigmella floslactella is difficult. host plants Betulaceae, oligophagous Carpinus betulus, orientalis; Ostrya…

Stigmella microtheriella larva parasite

Stigmella microtheriella Corylus avellana, Schinkelbos same larva, still in the mine. Carpinus betulus, Belgium, prov. Liège, Braives; © Jean-Yves Baugnée Contrary to Stigmella floslactella on the same hostplant, the mesonotum lacks a fine spinulation; see Gustafsson & van Nieukerken (1990a) for a description of the larva. 14/01/2013…

Stigmella floslactella parasite

Stigmella floslactella (Haworth, 1828) coarse hazel pigmy on ? Carpinus, Corylus Corylus avellana, Diemen same mine, detail Corylus avellana, Zeewolde, Harderbos © Hans Jonkman Carpinus betulus, Cadzand: aberrant mine (see below!) mine Oviposition at the underside of the leaf, in a vein axil. Mine a slender, gradually widening corridor; the…

Stigmella johanssonella parasite

Stigmella johanssonella A & Z Laštuvka, 1997 from A & Z Laštuvka (1997a) mine Rather slender gallery with a broad central frass line. The last part of the corridor follows (always?) a side vein. host plants Betulaceae, monophagous Ostrya carpinifolia. phenology Three or more generations. distribution within Europe From Austria…
