蛛緣蝽科

蛛緣蝽科（學名：Alydidae），又名蛛緣椿象科，是半翅目緣蝽總科下的一個科。本科物種與緣蝽科物種有著密切關係。現時本科包括有至少50個屬、 290個物種。
分佈於溫帶及地區上較溫暖的地區，本科物種主要為熱帶及亞熱帶昆蟲。舉例說：在歐洲本科有10個屬的物種，當中只有2個屬有在較溫暖的地中海區域以外出現。

**型態描述**
一隻見於喀拉拉邦的Riptortus屬物種。
Broad-headed bugsYiu 2012 are up to 1 long, and have slender bodies. Some have long and very thin legs. The most notable characteristics of the family are that the head is broad, often similar in length and width to the 前胸 (昆蟲) and the , and that the last 觸角 segments are elongated and curved. The 複眼s are globular and protruding, and they also have . The 腿 (節肢動物) of the hindlegs bear several strong spines; the tarsus has three segments. Most species have well-developed 翅鞘 (forewings), allowing them to fly well, but in some the hemelytra are vestigial. The membranous part of the hemelytra have several closely spaced long veins.
Alydidae are generally of dusky or blackish coloration. The upperside of the 腹 is usually bright orange-red. this color patch is normally not visible as it is covered by the wings; it can be exposed, perhaps to warn would-be 捕食s of these animals' noxiousness: They frequently have scent glands that produce a stink considered to be worse than that of true stink bugs (蝽科). The stink is said to smell similar to a bad case of 口臭.
Sometimes the adults have  reduced wings. Both, nymphs and adults of some species, such as  and  spp. are 擬蟻現象s and live in ant nests.

**棲息地與生態**
這些昆蟲主要棲息於相當乾旱的沙質棲息地，見於海濱、石楠荒原、乾草原和疏林草原。牠們的主要以植物的種子為食：牠們會用其長鼻刺穿種子，以飲用其中所含的營養液。部分物種在經濟上是重要的害蟲，例如水稻上的。

**分類**
本科物種為單源群Li & Zheng，可分為三條自然的家系。這三條家系原來對應本科的三個族，分別如下Li & Zheng：- 蛛緣蝽族（Alydini）、- 稻緣蝽族（Leptocorisini）和- 微翅緣蝽族（Micrelytrini）。
1965年，有兩份文獻對這分類作出不同的修訂：- Ahmad (1965) Ahmad 1965將三個族都提升至亞科級，分別為ITIS_108249：
** 蛛緣蝽亞科 Alydinae
** 稻緣蝽亞科 Leptocorinae
** 微緣蝽亞科 Microelytrinae- 而Schaefer (1965)的提議將本科物種只分為兩個亞科Schaefer 1965：
** 蛛緣蝽亞科不變；
** 稻緣蝽族（Leptocorisini）與微翅緣蝽族（Micrelytrini）合組成為微緣蝽亞科。
中國昆蟲學家李新正和鄭樂怡於1993年發表研究，對蛛緣蝽科各個亞群合共16個代表屬作比較形態學研究，結論認同Schaefer (1965)的分類建議才符合研究結果Li & Zheng。其後，Schaefer (1999)Schaefer 1999再完善整個分類。不過，Ahmad (1965)的分類仍然有文獻在使用。
