Cicada nymphs of some species are famous for this. There are also some arctic insects, such as caterpillars, which stay in their larval form for many years and only awaken in the brief summer to eat. It takes them many brief summers to grow large enough to pupate, which is why they live so long.
The Cicada
You probably mean cicadas that remain underground for 17 years, emerge, lay eggs and die
The insect is a cicada. (family includes the co-called 17-year locust)
No, since the only factors of 17 are 1 and 17. therefore 17/100 stays as 17/100
17 days
He stays 17 forever, but his ACTUAL age is 109.
85% of 17 years= 85% * 17= 0.85 * 17= 14.45 years
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.
For some reason, Nature allows most insects to live only a short time compared to other living things on earth. But there is one insect that enjoys a longer life span than many members of the animal kingdom. There is a species of the cicada that actually lives for 17 years! No other insect comes anywhere near it in length of life, except perhaps a termite queen. The cicada's "life", however, is not exactly one that other insects should envy. It sleeps in the ground for those entire 17 years, comes out to enjoy only five weeks of life in the sun, and then dies! Why does it take 17 long years for nature to develop this little insect? No one knows the answer. All we know is that a female cicada lays eggs on the twigs of trees.When the young are hatched from those eggs they drop down, burrow into the ground, and attach themselves to roots. And these young cicadas, which are called "nymphs", remain there motionless for 17 years, sucking the sap of the roots! Then some kind of mysterious instinct makes them decide to go out into the light. They climb the trunk of a tree, their skins split open, and the mature cicada emerges. The male cicada is the one who makes that shrill sound you hear in the countryside. Scientists say that the noise-making instrument of the cicada is the most complicated musical organ to be found in nature. The male cicada has little drumlike plates which are constantly kept vibrating by muscles that never seem to get tired. There are more than 800 species, or kinds, of cicadas, and 100 of these are found in North America. But the 17-year cicada is found only in the United States. Most species of cicadas live only two years
Some species of cicada do come out every 17 years, but others have different life cycles and time periods for when they come out.
17 years old.
some are but it depend what species you are talking about.
