Top: An ant in Mozambique Bottom: An ant-mimicking spider, Myrmarachne Ant mimicry or myrmecomorphy is mimicry of ants by other organisms; it has evolved over 70 times. Ants are abundant all over the world, and potential predators that rely on vision to identify their prey, such as birds and wasps, normally avoid them, because they are either unpalatable or aggressive.
Bolas: Bolas spiders are unusual orb-weaver spiders that do not spin the webs. Instead, they hunt by using a sticky 'capture blob' of silk on the end of a line, known as a ' bolas '. By swinging the bolas at flying male moths or moth flies nearby, the spider may snag its prey rather like a fisherman snagging a fish on a hook.
Ant mimicry in many spiders and other arthropods may be for protection from predators that hunt by sight, including birds, lizards and spiders. However, several ant-mimicking spiders prey either on ants or on the ants' "livestock", such as aphids. When at rest, the ant-mimicking crab spider Amyciaea does not closely resemble Oecophylla, but ...

Luckily, spiders eat mostly insects -- especially the ones you may also find in your home. But as spiders get bigger, so do their prey, and larger arachnids feast on lizards, birds and small mammals.
Acanthaspis petax is a species of assassin bug that preys primarily on ants, but also on a variety of small insects, such as flies, small grasshoppers and beetles. [1] The nymphs of this species create a pile of ant carcasses on their backs for camouflage. [2] [1] The adults do not use camouflage and are coloured with a red and black pattern. [1]
The spiders do not appear now to have a negative impact, Shockley said, but as they continue to multiply, they could start to displace native spiders as they eat insects the native spiders also ...
