Chan's megastick 陈氏大竹节虫
While most insects can fit in the palm of your hand, there are a few giants out there. The longest in the world is a stick insect that lives in Borneo. It was named after its discoverer as Chan's megastick in 2008.
大部分昆虫都能装进你的手掌之间,但是有些格外大型的昆虫。世界上最长的昆虫是在婆罗洲(马来西亚)生活的竹节虫。2008年,这个物种以其发现者的名字命名为陈氏大竹节虫。
The largest known example is over 0.5m (22") long with legs outstretched and is kept at the Natural History Museum in London, UK.
已知的最大的一只在四腿伸直后超过半米长,现保存在英国伦敦的自然历史博物馆里。
Very little is known about the insect because in the wild it is exceptionally difficult to see. Males are brown and females mottled green, and both are long and spindly, so they are perfectly camouflaged in their rainforest home.
人们对这个物种鲜知寡闻,因为在野外要找到它如同登天。雄性竹节虫为棕褐色,雌性为迷彩绿,两者都体型修长若柳,所以能够和他们生活的雨林完美地融入一体。
To further mimic the plants around them, the eggs of the insect resemble seeds and have wing-like extensions, which are thought to help them to disperse on the wind.
为了模仿得更像身边的植物,连它们下的蛋都貌似种子,蛋上还有羽翼一般的延展,可以随风而动,更好地帮助它们扩散。
Experts believe Chan's megastick lives in the forest canopy, making it even more challenging to find. Only a handful of specimens are currently known to science.
专家们认为,生活在大森林的掩盖下的陈氏大竹节虫让寻找它们难上加难。至今科学界只有为数不多的几个标本。
