How to identify the Dog-day Cicada

A large, stout insect with a wide head, widely spaced eyes and clear wings held like a roof over the body.
Body is black and green with a pale belly; the wing veins are green.
Empty brown shells (exoskeletons) left on tree trunks are a sure sign cicadas are nearby.
Size: 27–33 mm.

Where it lives

Common in eastern North America in mid to late summer, in forests, parks and leafy suburbs. The young live underground for several years feeding on tree roots before climbing out to become adults.

Is it dangerous?

Cicadas are harmless to people and pets. They do not bite or sting and carry no disease. A dog that eats many may get an upset stomach, but cicadas are not poisonous.

Frequently asked questions

Why are cicadas so loud?

Males vibrate drum-like plates on their bodies to call females. A chorus can be louder than a lawnmower.

Do cicadas damage trees?

Females cut small slits in twigs to lay eggs, which can harm very young trees. Mature trees recover easily.

Can my dog eat cicadas?

A few are not harmful, but eating many can upset a dog's stomach. Ask a vet if your dog seems unwell.
