Choresine

Choresine is a genus of beetles that belong to the Melyridae family. This genus of beetle is known to have high levels of batrachotoxins and is believed to be a possible toxin source for Pitohui and Blue-capped ifrit birds in New Guinea. The locals advise against allowing these beetles to touch the eyes or sweaty face as a severe burning sensation can result. The name "nanisani" is used by villagers in Herowana in the Eastern Highlands Province equally for this group of insects, the numbing, tingling, burning sensation they cause and the Blue-capped ifrit. The hypothesis that Phyllobates frogs in South America obtain batrachotoxins from related genera of the Melyridae (Choresine does not occur there) has not been tested due to the difficulty of field-work in Colombia.
