Photos of Two-Clawed Hunting Spiders (Dionychans)

 

Many members of this group of families are highly conspicuous and active while others are masters of immobility and camouflage. The active hunters include jumping spiders (Salticidae). On the other hand, many thomisids (crab spiders) typify "sit and wait" prey capture strategy. Individuals may wait in inflorescences and attempt to grab prey that visit the flower for nectar or pollen (see photos below). Dionychans produce silk but in general, as with other types of hunting spiders and mygalomorphs, they do not use it directly to ensnare prey.
