Anasaitis canosa (Twinflagged Jumping Spider)

Common Names

Common Names in English:

Jumping Spider, Twinflagged Jumping Spider

Description

Family Salticidae

Jumping spiders get their name from the sometimes spectacular leaps they make when pouncing on prey or simply hopping about in the foliage . They are very small to medium sized spiders 3-15mm (1/8 -- 5/8") long. Their eight eyes are arranged in 3 rows - the first row near the midline contains the largest pair, which faces forward in the manner of predatory animals requiring binocular vision, and a second, smaller pair outboard of those, also facing forward and slightly upward. The second row of eyes is very mach smaller and facing upwards and only slightly forward. Our page on the bold jumping spider, Phidippus audax has many pictures showing the jumping spider's eye arrangement. The jumping spiders have the most acute eyesight of all spiders.[1]
