''Caloptilia octopunctata'' is a moth of the Gracillariidae family. It is known from the Democratic Republic of Congo, Tanzania, Uganda, South Africa, India, Australia (New South Wales and Queensland), New Zealand and Indonesia.〔(Global Taxonomic Database of Gracillariidae (Lepidoptera) )〕 The wingspan is 9–13 mm. The larvae feed on ''Homalanthus'' species, ''Omalanthus populifolius'', ''Sapium ellipticum'', ''Sapium indicum'' and ''Sapium sebiferum''. They mine the leaves of their host plant. Mines are always started at the upper epidermal layer. The mine at first is narrowly linear, upper epidermal, and transparent-whitish in colour, then it widens to an irregularly blotch-formed mine, which is upper parenchymal and greenish-brown in colour. The third instar larva, transforms to the tissue-feeding type, continues feeding within the minecavity. The mine in this stage is completely changed in colour to pale brown, and slightly contorted on the upper epidermis with silken threads. After the moult, the 4th instar larva emerges from the mine through a round hole, and migrates to the margin of the same leaf or another one. It cuts a strip of the leaf along the margin and rolls up the strip into a cone on the lower side of the leaf. Then the larva continues to feed inside the cone. The larva seems to make one or more leaf-rolls during the remaining four instars. Pupation occurs within the final leaf-roll in a white and spindle-shaped cocoon.〔(Notes On Caloptilia (Sphyrophora) octopunctata (Turner, 1894) Of India, With Description Of Its Larva (Lepidoptera: Gracillariidae) )〕 ==References== 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「Caloptilia octopunctata」の詳細全文を読む スポンサード リンク
