Polyrhachis sp

Many arthropods such as spiders, praying mantis, beetles and assassin bugs mimic ants. Here is one ant that mimics another, this Polyrhachis species mimics Diacamma ants. From the head to the gaster this Polyrhachis species looks very similar to Diacamma. The main give away are the spines on the thorax.

In ants, mimicry is not restricted to morphological appearance but are very commonly expressed in behavior one of the most common of which is the raised gasters that in smaller species mimics fireants (i.e. Solenopsis and to some extend also Monomorium) and in larger species probably mimicry of Oecophylla smaragdina. This mimicry expression is usually targeting larger predators such as birds, lizards, frogs and even small mammals as obviously arthropods that prey on ants such as centipedes, scorpions, spiders, praying mantis, assassin bugs, etc are not exactly deterred.

This Polyrhachis species like most of this genus is monomorphic and polygynous.
