Cicada eggs take between six and ten weeks to hatch. The eggs are laid in slots which the female carves into twigs with her ovipositor. After hatching, the nymph fall to the ground where they burrow down 15-45 cm underground. Depending on the species, cicadas may spend from 2 to 17 years as nymphs underground, but contrary to what some may believe, this is not how long the actual eggs take to hatch.

The insect you are referring to is the periodical cicada. They spend most of their lives underground feeding on tree roots, then emerge in large numbers to mate, lay eggs, and ultimately die after about a week. This lifecycle can last either 13 or 17 years depending on the species.
Some species of cicada do come out every 17 years, but others have different life cycles and time periods for when they come out.
The three stages of a cicada's life cycle are egg, nymph, and adult. The eggs are laid in tree branches, where they hatch into wingless nymphs that live underground and feed on tree roots for several years before emerging as adults. The adults then mate, lay eggs, and the cycle repeats.
Meerkat pups stay underground for about three weeks. After that they go above ground and hang out at the burrow with a baby sitter for a few days. Than they can go out learning to forage with all the other meerkats.
