水虫vs Cockroach
而很难混合水蝽与cockroaches, despite the common reference of cockroaches as water bugs. As the common names imply they live in different ecosystems. Additionally, their ecological roles are different to each other. With some more important differences, including the external appearance water bugs differ from cockroaches. This article presents information on both these insects and explores the differences between them.
水虫
几乎没有类型的昆虫称为水虫,但本文仅考虑了真正的水虫。真正的水虫属于下端:命令的新虫:半翅目。它们被称为真正的水虫,是它们的栖息地。最早的水虫化石可以追溯到2.5亿年。目前,大约有2,000种水虫物种,除极地地区外,它们在世界各地分布。大多数真正的水虫都生活在淡水中,而有些咸水和盐水种类也是如此。他们要成为半翅术,他们的前锻被固定在前方,但不是后半部。水虫缺少ocelli,但有时这些是残留物。水虫通常是杂食性的昆虫,它们以植物物质和猎物为食,并以小脊椎动物和两栖动物的小幼虫为食。但是,有一些巨大的水虫物种具有捕食某些鱼类和两栖动物的能力。
蟑螂
蟑螂是一群高度多样化的昆虫,拥有超过4,500种的昆虫,它们按以下顺序进行分类:Blattodea。有八个蟑螂家族,但只有四种变成了严重的害虫。但是,大约30种蟑螂一直生活在人类居住周围。蟑螂最重要的方面是它们承受大规模灭绝的能力。在一个简单的术语中,自3.54亿年前(在石炭纪时期)以来,蟑螂从未在地球上发生的任何大规模灭绝生存。与大多数其他昆虫相比,蟑螂很大,长约15-30毫米。记录最大的物种是澳大利亚巨型挖洞蟑螂,长大约9厘米长。他们都有一个小头的dorso-ventrally扁平的身体。口点适应任何类型的食物,这表明其广义食品习惯。因此,任何可用的东西都可能是蟑螂的食物。 Their basis of survival through more than 350 million years is well explained using their generalised food habits. They have large compound eyes and two long antennae. The whole body is not as hard as in many insects, but the first pair of wings is hard and the second pair is membranous. Their legs have coxae and claws for protection and other functions. Cockroaches could be serious pests not only for food destroyers, but also as dispersal agents of diseases such as asthma.
水虫和蟑螂有什么区别? •蟑螂比水虫更多样化。 • Cockroaches exist more than 100 million years before the water bugs did. •蟑螂比水虫更普遍。 •蟑螂用蟑螂充分硬化,而只有前一半的前孔在水虫中被硬化。 •蟑螂可能是严重的害虫,而不是水虫。 •身体在蟑螂中呈圆形,但在水虫中不扁平。 •蟑螂有一双大眼睛,但是ocelli是残留物中的残留物或不存在的。 |
