Both species captured a wide assortment of spider species but also a few insect species. Behavioural capture adaptations include a slow, stealthy approach to the prey followed by a very fast attack. Morphological capture adaptations include scopulae on forelegs used in grabbing prey body parts, stout forelegs to hold the prey firmly, and and extremely thick cuticle all over the body preventing injury from a counter bite of the prey.
