A team of scientists studying freshwater ponds on an Australian island observed a rather peculiar mosquito behavior – when feeding on frogs, mosquitoes would always go for the nostrils.
John Gould and Jose Valdez – the first with the University of Newcastle, in Australia, the other the German Center for Integrative Biodiversity Research – spent three years surveying approximately 60 freshwater wetland ponds on Kooragang Island, in New South Wales, Australia. During their research, they observed and photographed a total of 3977 amphibians, but upon returning to their laboratory and laying out all of their photos, they noticed something intriguing. Out of their thousands of photos, 12 of them showed mosquitoes feeding on various species of frogs, but in all of them, the mosquitoes were sucking blood from the animals’ nostrils.
