This is the most polymorphic of the New World tree vipers. This venomous snake may be clad in scales of orange, various shades of yellows, olive, brown, and dull green to rich moss green. Darker or contrastingly colored crossbands, flecking, or spotting may be present. The brilliant yellow (oropel) phase and the moss green and strawberry (Christmas tree) phases are particularly coveted by hobbyists.
Although a few are now being imported from âsnake farmingâ operations in Costa Rica, the majority of those offered in the American pet trade are bred by American hobbyists. Imports and neonates can be reluctant feeders and difficult to acclimate. However, once they are feeding regularly, eyelash vipers are hardy captives. Adults usually readily accept prekilled lab mice offered on forceps. Neonates may accept a pinky mouse scented with a frog.
Eyelash vipers are quiet snakes and may remain in the same position for days on end. However, they can move quickly when necessity dictates, and if frightened may either gape widely or strike quickly and accurately.
Because they are a fairly small and very inactive snake, a relatively small terrarium will suffice for their husbandry. A vertically oriented terrarium of 15 or 20 gallon capacity is large enough for a pair or trio of adults. With a secure and sturdy climbing limb or two (preferably with comfortable forks), elevated corkbark hides, and a hardy live plant (such as an Epipremnum [Pothos]) a beautiful and very usable terrarium setup can be designed.
