If a mosquito is carrying a disease and bites a human, they could get malaria, which can cause death. Frogs decrease the chance for humans to get deadly diseases like that.

Insects are often differentiated by their particular mouth parts - which aids in their identification. Insect mouth parts fall into different categories depending on the insect type. Each has a certain tool for dealing with certain prey. Houseflies utilize spongy pads that secrete saliva over their food, dissolving the food source which can later be sucked up through their straw-like mouth. Other insects like mosquitoes have a needle-like mouthpart useful for breaking through skin and
