What cues do frog-biting midges use to find their host?

December 2014


Frog-biting midges (Coretherella spp) are known to use the mating calls of frogs to find their host. Until now, however, the potential use of other host-emitted cues in this group had not been investigated. In this forthcoming study we examined whether frog-biting midges use carbon dioxide or temperature, commonly used cues by many hematophagous insects. Our results revealed that the midges do not use any of those cues and depend on frog calls for their host-seeking behavior.
