Question: how big can a cicada get?
Answer: There are around 3,000 cicada species, according to National Geographic, so they vary in size from 0.75 to 2.25 in (2.2 to 5.5 cm) long. Cicadas can be black, brown or green and can have red, white or blue eyes. Their wings are transparent and can seem rainbow-hued when held up to a light source.
