| Immature periodical cicadas (nymphs) develop underground and suck juices from plant roots. After 13 or 17 years below ground, mature nymphs emerge from the soil at night into the morning hours and climb onto nearby vegetation or any vertical surface. They then molt into winged adults. Their shed outer skins or exoskeletons are found attached to tree trunks and twigs. |
