Anasaitis canosa
''Anasaitis canosa'', previously of the genus ''Corythalia'', is a small jumping spider that can typically be found atop leaf-litter or man-made structures such as fences and exterior walls. This species is more commonly known as the twin-flagged jumping spider due to the two pennant shaped markings on the dorsal side of the cephalothorax. Typical of the genus ''Anasaitis'', this species has iridescent setae ("scales") which may appear white, green or pink which create the "flags" as well as patches on the male pedipalps used in courtship and intraspecific signaling. This species is roughly one centimeter in length and has a lifespan up to two years. ''A. canosa'' ranges from Mexico to South Carolina along the Gulf of Mexico.
==Hunting behavior==
This species exhibits an instinctive and unique hunting method for catching ants. The spider will align its abdomen and thorax so that it directly faces the ant, and then strafe in an arc until the ant is directly facing the spider. Once aligned, the spider will leap and puncture the ant on the dorsal side of the head or thorax. In this position, the dangerous mandibles and stinger are incapable of inflicting damage. When stalking prey such as flies or beetles, this salticid is much more direct in its approach and will pounce and puncture from any direction, presumably because these prey pose less risk to the spider. As is common with Salticids, this species uses its silk as a tether whenever leaping. In the event of a miss, they will climb up this silk line back to the previous perch.
