Catyr, the first part of catyrpel, may indicate the existence of an English word.cater, meaning "tomcat,”otherwise attested only incaterwaul. Cater would be cognate with Middle High German kater and Dutch kater. The latter part ofcatyrpel seems to have become associated with the word piller, "plunderer.” By giving the variant spelling -ar, Johnson's Dictionary set the spelling caterpillar with which we are familiar today. 似乎蛾子和蝴蝶的幼虫经常会被看成与其它较大动物相似。意大利方言中gatta， 一字，“猫，毛虫”； 日耳曼方言中tüfelskatz 一字“毛虫”（直译为“邪恶的猫”）； 法语词chenille， “毛虫”（来自民间拉丁语小词缀， canicula， 源自 canis ，是“狗”的意思）； 最后但并非不重要的一点，英语中caterpillar 一词， 可能是来源于从法国北部传来的古法语词汇chatepelose， 字面意思是“多毛的猫”。caterpillar 一字于1440年最早记录在英语中， 以catyrpel的形式出现。 Catyr是 catyrpel 的第一部分， 可能指明英语词cater 的存在， 意指“雄猫”，否则只能存在于caterwaul一词中。 Cater可能与中世纪高地德语 kater 和荷兰语 kater 有关。 catyrpel 一词的后一部分似乎与 piller 一词有关，意思是“强盗”。 约翰逊的词典 给出了不同的拼写- ar， 从而形成了我们今天所熟悉的 caterpillar 〔gallfly〕Any of various small insects, such as the gall midge or gall wasp, that deposit their eggs on plant stems or in the bark of trees, causing the formation of galls in which their larvae grow.瘿蝇：一种小昆虫，例如瘿蚊或瘿蜂，他们把卵产在植物的茎内或树皮内，幼虫在里面生长并产生虫瘿〔spat〕An oyster or similar bivalve mollusk in the larval stage, especially when it settles to the bottom and begins to develop a shell.幼牡蛎：幼虫时期的牡蛎或类似双壳类软体动物，尤指在海底开始开壳的〔permethrin〕A topical insecticide, C21H 20CL 2O 3, used to treat head lice and nits, scabies, and various species of ticks. 百灭宁：局部杀虫剂，C21H 20CL 2O 3，用于对付头部虱子及其幼虫、疥癣与多种扁虱 〔parasitoid〕Any of various insects, such as the ichneumon fly, whose larvae are parasites that eventually kill their hosts.拟寄生物：如姬蜂等几种昆虫中的任意一种，它的幼虫便是寄生物且最终会杀死宿主〔worm〕Any of various crawling insect larvae, such as a grub or a caterpillar, having a soft, elongated body.幼虫：几种爬行昆虫幼虫的一种，如蛆或毛毛虫，有柔软的，细长的身体〔nit〕The egg or young of a parasitic insect, such as a louse.虱卵：寄生昆虫的卵或幼虫，如虱子〔coenurus〕The parasitic larval stage of the tapewormTaenia multiceps that consists of a cyst in which the scolex develops and that infects the central nervous system of ruminants, especially sheep. 共尾幼虫：绦虫多节绦虫 的寄生虫幼虫阶段，有囊胞，头节在其中生长，使反刍动物尤其是羊的中枢神经系统感染 〔chigger〕Any of various small, six-legged larvae of mites of the family Trombiculidae, parasitic on insects, humans, and other vertebrates.
