Diet The diet of S. bicolor is unknown.Pryon, R. Alexander; Guayasamin, Juan M.; Peñafiel, Nicolás; Bustamante, Lucas; Arteaga, Alejandro (2015). "Systematics of Nothopsini (Serpentes, Dipsadidae), with a new species of Synophis from the Pacific Andean slopes of southwestern Ecuador". ZooKeys 541: 109-147. (Synophis bicolor, p. 127).
