蝽Pentatomidae--是一種,通常被稱為"shield蟲","chust蟲"和"椿象Stink bug".
大約有7,000種.(若包括半翅目昆蟲科,可以達到80,000).
Pentatomoidea is a superfamily of insects in the Heteroptera suborder of the Hemiptera order.They are commonly referred to as shield bugs,  bugs, and stink bugs.There are about 7000 species under Pentatomoidea.

















蝽的特點是,一個發達的盾片(硬化延伸超過腹部的胸部)。它可以是三角形,半橢圓形的形狀.觸角通常有5段。踝骨通常有兩段或三段.
Pentatomoidea are characterized by a well developed scutellum (the hardened extension of the thorax over the abdomen). It can be triangular to semi-elliptical in shape.Pentatomoidea usually have antennae with five segments. The tarsi usually have two or three segments.












蝽在自己的胸部腺體之間的第一和第二對腿產生惡臭液體。這種液體是用來防守的,以防止潛在的掠食者.(所以又有放屁蟲、臭板蟲、臭大姐等俗名。中國已知約500種).
Bugs have glands in their thorax between the first and second pair of legs which produce a foul smelling liquid. This liquid is used defensively to deter potential predators .












幼蟲和成蟲的口有吸管,其中大部分用於吸食植物汁液,當他們大量出現,就可以成為重大的害蟲。
The nymphs and adults have piercing mouthparts, which most use to suck sap from plants . When they group in large numbers, they can become significant pests.

然而,一些蝽屬被認為是有益的:"anchor bug,或 anchorago",可以由成蟲上的橙紅色的錨形區分.它是一種喜歡捕食其他昆蟲的蝽,尤其是墨西哥豆甲蟲,日本甲蟲和其他害蟲。
However, some genera of Pentatomidae are considered highly beneficial: the anchor bug, which can be distinguished by the red-orange anchor shape on the adult, is one example. It is a predator of other insects, especially Mexican bean beetles, Japanese beetles, and other pest insects.
