Why do cicadas scream when you touch them?

Cicadas don't "scream" when touched; the sound is a loud alarm or distress call produced by males using special vibrating membranes (tymbals) on their abdomen, amplified by their hollow bodies, to startle perceived threats like predators or you, signaling danger and attracting females. It's a sudden burst of intense buzzing or clicking, an instinctive defense mechanism triggered by being handled, not an actual scream.

Why do cicadas scream when you pick them up?

It's part of their defense mechanism as they do not make the same “screaming” noises as the males. The males will call (they produce this sound using something called tymbals) when picked up. But specifically when they are flicked or run into something they might just be stunned (both males and females).

Why do cicadas fly right at you?

Cicadas fly at you by accident because they mistake you for a tree, attracted to your dark, upright silhouette, especially when you're in an open area during their mass emergences, and since they're clumsy flyers, they might bump into you, but they don't bite or sting and are just looking for a place to mate. It's a case of mistaken identity and overwhelming numbers, not aggression.

A few are usually fine, but large quantities can lead to stomach upset, and in rare cases, dogs might have a contact allergy or a shellfish-related allergy.

What happens if a cicada attacks you?

Cicadas do not bite or sting because they don't have the mouthparts or stinger to inflict a bite. They instead use a long, straw-like tube to suck the fluids from trees. This means you might feel a slight prick when the insect lands on you, but don't worry, you can remove the cicada and go about your business.
