It is used medically to remove warts[1] and is collected for this purpose from species of the genera Mylabris and Lytta, especially Lytta vesicatoria, better known as "Spanish fly". In Montana, rocky alpine areas once harbored live trees that have turned into “gray ghosts,” denuded whitebark pines that died from either mountain pine beetle infestations or white-pine blister rust, a non-native fungal Bombardier beetles have the infamous ability to synthesize and release rapid bursts of stinky, burning-hot liquid from their rear ends.
