Biology

Polyrhachis muelleri nest.jpg

The fairly transparent silk-woven nest of about 10 cm in length is situated beneath a leaf of a ginger plant about 2 m above ground, in a primary rainforest. Larvae and pupae appear greenish; only the adult ants are black and thus well visible against the sunlight.

The biology of P. muelleri was described in detail by Dorow et al. (1990). Colonies are monogynous with 17 workers on average (n=19)

Castes

Very slight difference in body size between queens and workers (Dorow et al. 1990)
