If any of their variable colors could be considered normal, it is this phase with the mossy green ground color.
I have always been enamored of arboreal vipers, be they of the America’s, Africa, or Asia. I was so infatuated with them that at one time Patti and I kept and bred, or at least tried to breed, 30+ species. But, truth be known, although I found all of interest and beautiful, over the years two of my favorites became and remained, 2 of the more commonly seen Central and South American species, the 2-lined forest pit vipers,
Bothriopsis bilineatus, and the eyelashed pit piper,
Bothriechis schlegelii. Why these 2? I just don’t know. But even between the two I favored one over the other, this being the eylashed species.
Perhaps it was the ease with which this variably colored snake could be housed, fed, and bred. Or perhaps it was the overall hardiness. Then again, I guess that it could have been the remarkable and entirely natural variability of color. You like ‘em green, the eyelashed viper comes in several naturally occurring phases that vary from a dusky forest green to pale green. If you like something different and don’t mind searching a little, you will likely be able to find an orange –red, a yellow-orange, a bright yellow (the latter is known as the “oropel” phase), or a yellow with greenish or dusky bands (the “tiger” phase).
It was many years after I had acquired my first trip of eyelashed vipers that Patti and I had an opportunity to meet this snake in the wild. We went to Costa Rica. Patti called it a Honeymoon. I called it a herping trip. On the first afternoon, after walking a rainforest trail and marveling at poison frogs and minute geckos, as we walked back to our hotel I glance at a small banana tree that edged the path and stopped dead in my tracks. I was looking at a small grayish B. schlegelii! I hadn’t even known they came in that color.
Since then I have seen a few others in the field. Admittedly, not many, but among those seen have been an oropel and one of mossy green. What wonderful snakes!
This snake has an interesting defensive display during which it opens its mouth widely and faces the perceived threat. The snake will bite if threatened and envenomation has resulted in human death.
