Lycodryas are arboreal snakes that are believed to be active hunters. However, their ecology is generally poorly known.[1]

Lycodryas are markedly elongated, slender-bodied snakes with often striking coloration. The head is distinct. They typically have 8 (range: 7–9) upper labials and 6–10 lower labials, 1 loreal scale, 17–19 rows of dorsal scales at mid-body and 13 or 15 rows of dorsal scales at the last ventral, 185–284 ventral scales, anal plate that is usually divided, and 70–130 subcaudal scales. The contracted pupil is a small vertical ellipse.[1]
The following nine species are recognized as being valid.[2]
- Lycodryas citrinus (Domergue, 1995)
- Lycodryas cococola Hawlitschek, Nagy & Glaw, 2012
- Lycodryas gaimardii (Schlegel, 1837)
- Lycodryas granuliceps (Boettger, 1877)
- Lycodryas guentheri (Boulenger, 1896)
- Lycodryas inopinae (Domergue, 1995)
- Lycodryas inornatus (Boulenger, 1896)
- Lycodryas maculatus (Günther, 1858) – spotted tree snake
- Lycodryas pseudogranuliceps (Domergue, 1995)
Nota bene: A binomial authority in parentheses indicates that the species was originally described in a genus other than Lycodryas.
