The Blood-vein, (''Timandra comae'') is a moth of the family Geometridae. It has a scattered distribution in Western and Central Europe north of the Alps. In the British Isles the distribution is patchy outside southern England and Wales. In far eastern Europe – east of a line running roughly from Finland through Estonia –, it is replaced by its sister species ''Timandra griseata''. The species were split in 1931, only to be subsequently re-merged by most authors. But since 1994, new research has come out in favour of treating them as distinct species.〔Õunap ''et al' (2005)〕 The wings are cream-coloured with bold red or purple fascia forming a diagonal stripe across forewings and hindwings. All wings are fringed with the same colour. The tornus of the hindwing is sharply angled giving a distinctive shape. The wingspan is 30–35 mm. Two broods are produced each year with the adults flying in May and June and again in August and September . It flies at night and is attracted to light. The larva is grey-brown with darker spots on the back. In the UK, it feeds on the leaves of a variety of plants including dock, knotgrass, sorrel and various species of ''Atriplex''. It overwinters as a larva. # ''The flight season refers to the British Isles. This varies in other parts of the range.'' == External links == * (Lepiforum ) * (UK Moths ) 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「Blood-vein」の詳細全文を読む スポンサード リンク
