This question is equivalent to asking what multiples of 13 and 17 are equal, and more specifically, what is the lowest multiple of 13 that equals a multiple of 17 or what is the lowest multiple of 17 that equals a multiple of 13. Since 13 and 17 are prime, they have no factors in common. This means that the lowest common multiple is equal to 13 x 17 = 221. Therefore, it will be 221 years before the 13 and 17 year cicadas appear together again.
What else can I help you with?
How many years after an appearance of 13 year and 17 year cicadas together will both types of cicadas appear together again?
Cicadas have distinct 13-year and 17-year life cycles. After appearing together, the next time both types will emerge together again is in 221 years (13 * 17 = 221).
If Cicadas have predators with 2 year hibernation cycles how often would 12 year cicadas face their predators?
how often would a 12 year cicada face its predator with a 2 year cycle?
Suppose there were 12 year 14 year and 16 year cicadas and thy all came up this year how many years will elapse before they all come up together again?
240? How about 336? The lowest common factor is 2. 2X6 = 12 2x7 = 14 2x8 = 16 so.... 6x7x8 = 336
How did the cicadas decide that they would wait a prime number of year before emerging?
To think of cicadas as "deciding" something is anthropomorphizing; that is, using words that describe human attributions with things that don't really think as humans do. What probably happened is that those cicadas which happened to have a prime number cycle tended to avoid having predators match their periodic appearances and so increased relative to those that didn't, and as a consequence, got eaten. This is Natural Selection. Incidently, only Periodic cicadas have prime number cycles (17 or 13 years); there are also Annual cicadas which as their name implies, appear every year.
What do 17 year locusts eat?
17 year "locusts" are cicadas rather than actual locusts. They feed on tree sap.
Are cicadas found in Ontario?
Yes. I usually find several in my backyard each year in Thamesford, Ontario.
How many cicadas stay underground for 13?
Certain species of cicadas, particularly the periodical cicadas, spend 13 years underground as nymphs before emerging as adults. This life cycle is characteristic of the 13-year cicadas, which belong to the genus Magicicada. There are four species within this group, each synchronized to emerge in specific years, resulting in massive swarms. Their unique life cycle is an adaptation to avoid predation and ensure survival.
If cicadas come every 17 years and caterpillars every 6 years what year will they coincide?
every 102 years
The 13-year and 17-year cicadas are isolated by what?
The 13-year and 17-year cicadas are isolated by their different life cycles and emergence patterns. This isolation prevents them from interbreeding and eventually leads to separate populations with distinct emergence times.
What year did the key first appear?
What year did the key first appear?
What happens every seventeen years?
Every seventeen years, a species of cicadas known as periodical cicadas emerge from the ground in large numbers, primarily in the eastern United States. This emergence occurs in synchronized cycles, with different broods appearing in different years, but the most famous are the 17-year cicadas from Brood X. These cicadas spend most of their lives underground as nymphs before emerging as adults to mate, lay eggs, and then die shortly after, a phenomenon that creates a significant impact on local ecosystems.
