Nothing is known about the biology of Simopelta bicolor.


Mackay and Mackay (2008) - The worker of this species is easily recognized, as the mandible has six or more teeth. The clypeus lacks a spine. All other species in the genus have three-five mandibular teeth. The mesosoma is only slightly depressed at the promesonotal and metanotal sutures. It is bright, ferrugineous red with a yellow petiole and gaster.

The narrow petiole (as seen from the side) could cause confusion with the Brasilian Simopelta minima and the central and northern South America Simopelta pergandei, which also have narrow petioles. It can be separated from both of these species by the number of mandibular teeth: the latter two species only have three teeth.
