Question

Explain the cicadas’ “safety in numbers” strategy, making sure to mention the factors behind their emergence every 17 years.

Answer 1

Cicadas strategy ;  The preys(periodical cicada) move in larger numbers in order to stand a survival chance against predators.

The Cicadas strategy is a safety strategy practiced by preys to protect themselves against predators, so many preys employ different tactics to defend themselves against their potential predators. and some of the ways they tend to achieve this are :

• camouflaging to blend into the environment
• producing some kind of warning  coloration
• mimicking predators to confuse
• moving in large numbers ( flock or herd )

The Cicadas strategy ( moving in large numbers ) is one of such safety strategy that is practiced by an insect known as periodical cicadas. they are called periodical because they emerge from their hiding place once every 17 years and in very large numbers in order to stand a chance of survival. Although a lot of them get eaten but a lot of them survive as well to continue the reproduction cycle

Hence cicadas strategy is a strategy that protects weak preys when they move in large  numbers

Answer 2

Answer:

Basically it means that there's safety in numbers, so to speak. The insects emerge in such prodigious quantities that predators cannot possibly eat them all. The strategy depends on timing.They do little to defend themselves. They fly poorly, don't fight and taste great. In the parlance of animal behavior, cicadas are "predator foolhardy" -- they are always available for lunch. ... If too few cicadas emerge, or if they come out over an extended period of time, they are likely to be wiped out by predators.
