翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Dasymutilla occidentalis ： ウィキペディア英語版 Dasymutilla occidentalis ''Dasymutilla occidentalis'' (red velvet ant or eastern velvet ant), is a species of parasitoid wasp native to the eastern United States. It is commonly mistaken for a member of the true ant family, as the female is wingless. The species ranges from Connecticut to Missouri in the north and Florida to Texas in the south. Other common names include cow ant and cow killer. The eastern velvet ant is the largest of the velvet ant species in the United States, attaining an approximate length of 0.75 in (1.9 cm). Adults display aposematic coloration, consisting of black overall coloring with an orange-red pattern on the dorsal surface of the thorax and abdomen. They are covered in dense, velvet-like hair.〔〔 Females are capable of an extremely painful sting, hence the name "cow killer".〔 They are extremely quick-moving and often take a defensive posture when threatened. They seek out the brood cells of Eastern cicada killers and other large ground-nesting members of Crabronidae, where they deposit an egg onto a host larva. The egg quickly hatches into a white, legless grub, which consumes the host and goes through several larval stages prior to pupa formation. Unlike the females, males have dark, translucent wings and do not deliver a sting.〔〔 ==Appearance and features== Commonly mistaken for an ant, because of its appearance and its common name, it is actually a unique species of wasp in which the females are wingless. It can be recognized by its black and orange-red striped coloring. When looking for food and a place to nest, females crawl rapidly along the ground. They also make a squeaking noise to communicate concern. Males fly low over grass in search of female mates. One is able to determine males from females by whether the specimen can sting, because only females have the ability to sting, and whether the specimen has wings, as only males have wings. 〔Jackman, John.Venomous Terrestrial Animals of Texas.The Texas A&M University System.〕 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「Dasymutilla occidentalis」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.
