ELI5: How do insects bite humans and other large animals? Wouldn't the size of an insect's mouth biting a human arm, be comparable to a human biting a flat surface such as a table?

Insect mouthparts that are specifically designed to bite large animals (like mosquitoes and horseflies) are usually more like needles than jaws. Some insects that you might think of as biting insects, like fire ants, are actually stinging insects (again, with a needle-type design).
