Water-filled bromeliad as roost site of a tropical lizard,Urostrophus vautieri (Sauria: Leiosauridae)

Bromeliads are a conspicuous component of tropical forests. Whereas several amphibian species are closely associated with bromeliads, reptiles are much less frequently observed in bromeliads and only a few species use bromeliads for egg deposition or as roost site. We report on an adult Urostrophus vautieri that was sleeping in a water-filled bromeliad. The individual was submerged except for head and shoulder. To our knowledge, it is the first time that such behavior has been observed in an arboreal Neotropical lizard.
