Thomisidae Spider Red Abdomen,Introduction The widow spider genus Latrodectus Walckenaer, 1805 (Araneae: Theridiidae) has a worldwide distribution, occurring across multiple continents and oceanic islands. Latrodectus includes a suite of species commonly referred to as black widow spiders (e.g., the North American L. mactans (Fabricius, 1775) and L. tredecimguttatus (Rossi, 1790) in Europe), frequently recognized by their red abdominal “hourglass” mark, as well as the Australian redback spider (L. hasselti DARING JUMPING SPIDER Phidippus audax Jumping spider family (Salticidae) QuickID:black with tiny whitish hairs, 8 black eyes, bright green iridescent mouthparts (chelicerae) Length:0.51–0.78" Fascinating and amazingly successful little then use the silken.shelters to spend the winter in a state of dormancy WHITEBANDED CRAB SPIDER Misumenoides formosipes Crab spider family (Thomisidae) Quick ID: abdomen widest at rear, white line through eyes; male—shiny red, This field guide will be enjoyed by naturalists and anyone with an interest in learning more about Australia's incredible arachnids.THOMISIDAE.

They make no web; instead they stalk and pounce on prey byjumping distances many times their body length.

Spiders lack anten I nae and wings. Most spiders The Southern Black Widow ( Latrodectus mactans) is recognized by the red hourglass marking on the underside of the abdomen. Widow venom is neurotoxic, resulting in violent and CRAB SPIDERS (Thomisidae) include the Flower Crab Spider (Mis umena vatia).
