Details of the aggregation suggest an association with mating, and the existence of communal nesting in this species suggests that aggregation might occur for oviposition as well. & W. E. Duellman. These species, especially D. elegans and D. ellipsifera, have been confused in previous literature because of inadequate attention to patterns of sexual dimorphism and geographic variation.

Nat. Dipsas oreas is active nocturnally in low vegetation but seeks seclusion in leaf litter or under surface objects on the ground during the day. Dipsas elegans is unusual in that males have significantly more ventral scutes than females, the reverse of the more common colubrid pattern of sexual dimorphism, in which females have more ventrals than males; neither D. oreas nor D. ellipsifera is sexually dimorphic for this character. The last two species are resurrected from the synonymy of D. oreas. Dipsas elegans and D. ellipsifera share a distinctive color pattern that is quite different from color patterns in D. oreas.
