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 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…

Shape introduction

…are uncommon; examples are the mines of Lyonetia clerkella and of Stigmella microtheriella below. Stigmella microtheriella on Hazel However, in most cases the larva is capable of creating some more space. The better it manages to do so, the wider the corridor becomes, like the trumpet-shaped mines of most Aulagromyza-species….

Nepticulidae parasite

…Emmet (1983a) and Johansson ao (1990a). Stigmella microtheriella on Corylus avellana; larva, lateral view (the rod is 0.1 mm thick) The prolegs (often a lot smaller than shown here) don’t bear crochets; perhaps that is the reason why in literature they generally are referrred to as calli (“knobs”). They eye…

Corylus host plants

…Larva tight in the mine, venter upwards, head light brown. Exit slit usually at underside, rarely upper side: Stigmella microtheriella 4b gallery wider, especially in second half much wide than the larva; frass line variable, cloudy, at start often green, sometimes rather narrow, generally wide; mine not angular, not following…
