Leucoptera sinuella
Leucoptera sinuella, also known as the scotch bent-wing,[1] is a moth in the family Lyonetiidae. It is found in most of Europe, except Ireland, the Balkan Peninsula and the Mediterranean Islands.[2] It is also found in Japan (Hokkaido, Honshu) and North Africa. It is also invasive to South America, mainly in Argentina and Chile, and has been present there since 2015.[3][4][5] The wingspan is about 7–8 millimetres (0.28–0.31 in).[6] EggsEggs are deposited on the upperside of the leaf, mostly in groups of 5–10 along a vein. Although rare, a single egg can also be deposited. The empty shells are flat, circular and shining. [1] LarvaeThe larvae have a head and chewing mouthparts with opposable mandibles, and six thoracic and abdominal legs.[7] The larvae feed on Populus alba, Populus candicans, Populus deltoides, Populus gileadensis, Populus nigra, Populus tremula, Salix aurita, Salix caprea, Salix cinerea, Salix fragilis, Salix purpurea. [1] A larva forms a large, black-centred blotch on the upper surface of a leaf before mining the leaves of their host plant. There are sometimes several larvae to a leaf as mines may merge.[1][8] PupaThe pupae have visible head appendages, wings and legs which lie in sheaths.[7]
PupationPupation is solitary and external, under a conspicuous white spinning in the shape of the letter "H".[1] Pupation occurs mostly on the leaf. There is an exit slit in the upper epidermis.[9] References
