摘要或動機

安德遜蠅虎的卵期和幼蛛期共約需 22~26 天，需經歷 6 齡（6 次脫皮）而成年，每齡需要時間為23~32 天，從卵期到成蛛約3~4 個月左右，成蛛約可再活 3~5 個月，為不完全變態。安德遜蠅虎喜歡在食物充足和陰暗的草叢和牆壁底層活動，能適應的溫度範圍在 15~33℃之間。安德遜蠅虎的行為項目目前已知 14 種，其中 4 種與捕食行為有關（例如：頭胸部升降、潛行、撲擊、迂迴），3 種與爭鬥行為有關（例如：Z形舞蹈1、前足斜舉、奔逃）；5 種與求偶行為有關（例如：觸肢擺動、前足斜舉、繞行、Z 形舞蹈 2、交尾） 。但牠不獵捕比自己體型過大的獵物，主要以小型蠅類或彈尾蟲為食，其捕食獵物主要靠視覺或感覺毛，中前眼最遠可看到超過12cm距離的東西，跳躍力最遠可跳出15cm 的距離。對於蠅虎的分佈區域就觀察提出【蠅虎集中發散推論】 ：一區域內的各種蠅虎，必有其集中地。各種蠅虎由其集中地向外發散、擴張形成發散地，並與其他種蠅虎勢力範圍重合，形成多種蠅虎共存的共存區。Hasarius adansoni’s egg development and postembryonic development require 22~26 days. It takes 6 stadiums to become adults. Every stadium needs 23~32 days . The adults can live to about 3~5 months . There are 3~4 months from egg development to adult. Hasarius adansoni like to move in grass and at the bottom of wall where there is plenty of food and no light.The scope of temperature is 15℃ to 33℃.There are 14 elements of behaviors known for Hasarius adansoni, including 4 predatory elements（such as Raise andlowered cephalothorax、Stalk、Leap and bit、Detour） , 3 agonistic behavior elements （such as Zigzag dance 1、First leg erect、Suddenly run and leap）, and 5 courtship behavior elements（such as Palp waving、First leg erect、Circular detour、Zigzag dance 2、Copulation）.But they don’t catch captures which are bigger than themselves；their main captures are little flies and Homidia sp. Relying on their vision and sensation hair，Hasarius adansoni’s Anterior Median eyes can identify for up to 12cm；long jump can for up to 12cm. The inference of jumping spider’s distribution could be that different species of jumping spiders in an area are sure to have their respective center habitats. They spread from the center habitats to disseminated areas. Then they overlap with those of their species and form a shared section of multiple species.
