The adult beetles are about 8 mm long and beetles in different regions can have different colour patterns on their elytra. ==Colour forms and host plants== Beetles from different populations can be distinct in their biology, like coloration or behaviour. The larvae and adults from northern Europe (e.g. Finland, Sweden, Norway, Russia, and the Baltic states) feed and oviposit only on some willow species. The Central European populations, which are patchily distributed in Germany, Czech Republic, Poland, northern Italy and France, are mostly monophagous on birch.〔 Development of the insect is impaired if beetles are reared on their non-natural host, that is beetles from northern Europe are fed with birch leaves, or beetles from Central Europe with willow leaves.〔 The elytra colouration consists of red and black marks. Black marks predominate in the northern populations while in the central European population the colours red and black are about equally represented on the elytra. The darker forms heat up more quickly and might be an adaptation to the colder environment in northern Europe.〔 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「Chrysomela lapponica」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
