Eupholus weevil Spectacularly coloured weevil of the genus Eupholus which includes some of the most colourful weevils. Species identification based on personal communication with an expert I contacted. The colour may serve as a warning (aposematic coloration) to predators that they are distasteful (as they may feed on leaves which contain chemicals which are toxic to other animals). Eupholus species occur in New Guinea and adjacent islands.
