Stigmella microtheriella (Stainton, 1854)

(zoological nomenclature: valid name, available)

General information:

Nepticula microtheriella Stainton, 1854: 302.
Type locality: Great Britain, Lewisham
Type: Lectotype : Great Britain, Lewisham, on nut, e.l. 6.viii.1853 (Stainton); in coll. NHM, London.

Synonyms, misspellings, wrong determinations, etc.:
Stigmella cathepostis Kemperman & Wilkinson, 1985: 10. Type locality: Japan, Kyushu, Hikosan, Buzen. Junior subjective synonym.

Distribution:

The species is probably distributed throughout the Palaearctic region. In is known from most European countries, but also from the Russian Far East and from Japan (Nieukerken 2019). The vertical distribution has been documented from near sea-level to only about 900 m a.s.l. (Kurz & Kurz 2019).

Biology:

The species inhabits mixed deciduous forests, bushland, wood edges, clear cuttings and tall herb vegetation with young bushes of the larval food plant. In central Europe, probably two generations per year can be found with larvae in June and July and again from August till October (Kurz & Kurz 2019). The larvae may be influenced by utilization of the same foodplant by different other leaf-miners like Parornix carpinella, Parornix devoniella, Phyllonorycter coryli, Phyllonorycter esperella, Phyllonorycter nicellii, Phyllonorycter tenerella and Stigmella floslactella, but also larvae of the same species. All these may occur together also on one and the same leaf (Kurz & Kurz 2019).

Egg. The eggs are laid on the leaves of the foodplants. These are Corylus avellana, Corylus maxima, Carpinus betulus, Carpinus tschonoskii and Ostrya carpinifolia (Kurz & Kurz 2019, Nieukerken 2019).

Larva. The larva is whitish green. The mine is a long and slender corridor, which traverses the leaf. Especially on Carpinus and Ostrya, the mine may change abruptly its direction by about 90 degrees, when reaching a larger vein.
