| CicadaYear.com: cicadas are between 2 and 5 cm (1 to 2 inches) long. Cicadas have prominent eyes set wide apart on the sides of the head, short antennae protruding between or in front of the eyes, and membranous front wings. Some cicadas produce sounds louder than 100 dB! They modulate their noise by wiggling their abdomens toward and away from the tree that they are on. Some species have 17 year life cycles, e.g. the Magicicada, which is widespread in the USA. |

| Life Cycle of the Cicada |
|---|
That's when the developing cicada, called nymphs crawl out of the ground and climb up tree trunks. There, they stop and shed their skin to emerge as winged adults. Their adult, winged stage is a short one. Adults live about four to six weeks, and their only mission is to mate and lay eggs. The males produce a loud mating call – which is especially prevalent in the early morning and late evening. After mating, the female cicada cuts a deep slit in a small twig where she lays her rows of eggs, usually two to four dozen. Six weeks later, the eggs hatch and the larvae drop to the ground where they will burrow underground and feed on tree roots – starting the next 17-year cycle. Soon after they mate and lay eggs, adult cicadas die. Source: MSN |
