In one group of animals, the digestion of this food requires the mutualistic bacterium Aeromonas veronii. Adult male, but not female, Calyptra moths consume this food and are the only lepidopterans known to ordinarily do so. In many insects, the production of vitellogenin is only triggered by this food; females of such species are thus called (15[1])anautogenous because they require this food to produce eggs. (-5[1])In some organisms, the consumption of this food involves the (15[1])protein (*) hirudin. The fact that few vertebrates (10[1])consume this food is due to the need to cope with its extremely high concentrations of protein and iron. (10[1])The consumption of this food is enabled by saliva containing compounds (10[1])such as heparin that inactivate thrombin. For 10 points, name this food that is consumed by female mosquitoes and (10[1])by leeches and vampire bats. ■END■ (10[1])
