''Bucculatrix bechsteinella'' is a moth of the Bucculatricidae family. It is found in most of Europe, except Greece and Bulgaria. The wingspan is 7–9 mm.〔(UKmoths )〕 Adults are on wing from mid May to mid August.〔(Lepidoptera of Belgium )〕 The larvae feed on ''Amelanchier'', ''Chaenomeles'', ''Cotoneaster'', ''Crataegus douglasii'', ''Crataegus laevigata'', ''Crataegus monogyna'', ''Cydonia oblonga'', ''Malus domestica'', ''Mespilus germanica'', ''Prunus insititia'', ''Prunus spinosa'', ''Pyracantha coccinea'', ''Pyrus communis'', ''Sorbus aria'', ''Sorbus aucuparia'' and ''Sorbus torminalis''. They mine the leaves of their host plant. The mine has the form of a small, hook-like corridor, mostly in a vein axle. The frass is deposited in a thick central line. The larvae soon leave their mine and resumes feeding living freely on the leaf.〔(bladmineerders.nl )〕 Larvae can be found from June to August. They are greenish yellow with a darker head. Pupation takes place in a white, ribbed cocoon on detritus. ==Gallery== Image:Bucculatrix_bechsteinella_mining_larva.JPG|Mining larva Image:Bucculatrix_bechsteinella_externally_feeding_larva.JPG|Externally feeding larva Image:Bucculatrix_bechsteinella_hawthorn_leaf,_mined_and_with_a_cocoonet_under_which_the_larva_moults.JPG|Hawthorn leaf, mined and with a cocoonet under which the larva moults Image:Bucculatrix_bechsteinella_gnawed_hawthorn_leaf.JPG|Gnawed hawthorn leaf Image:Bucculatrix_bechsteinella_cocoon.JPG|Cocoon 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bucculatrix bechsteinella」の詳細全文を読む スポンサード リンク
