Weaver ant mimic crab spider grooms front foot. The arboreal weaver ant genus Oecophylla are ubiquitous in northern Australia, New Guinea and South East Asia. There are number of spider species in a small number of families that have taken advantage of this rich food resource, including larvae. Most opportunists belong in the large family of jumping spiders (Saliticidae). Simply looking like these acid-spraying ants is enough to discourage predators and the mimic does not feed on the ants. Some of these spiders have evolved to look like weaver ants, while others employ chemical deception in order to enter nests and exploit the larval food supply. The crab spider genus Amyciaea contains five Australasian species. They employ a combination of chemical and tactile deceptive techniques to lull the adult ant prey into a fatal state of intimate acceptance. Using its silk as a safety line this non-web building family have a highly evolved prey snaring technique. Whist all arthropods have a grooming response applied to the sensorial parts of their limbs and antennae (if they have them). Perhaps the grooming response of the front legs in this genus involves the transfer of 'ant seduction' chemicals via the 'saliva'??
