Our group has sighted at least 2 different cane toads (Bufo marinus) on the front steps of the research station here in Costa Rica, since we arrived just two days ago. Apparently they see it as a giant feeding ground, since insects congregate when the lights are on at night (one toad was spotted eating a moth). There seems to be some question as to the exact native range of this species, but cane toads haven't been in Monteverde very long. It certainly seems like their presence would be a threat to native insects. Perhaps someone in Costa Rica needs to start a cane toad leather goods company.
