Most cicada species are considered annual cicadas—though the term is a bit of a misnomer, as these insects live longer than just a year. Their life span, which is around
two to five years
, depends on how long it takes for them to reach a mature size and weight.
Why do cicadas take 17 years?
As trees go through their seasonal cycles, shedding and growing leaves, the composition of their sap changes. And when cicada nymphs feed on that sap, they likely pick up clues about the passage of time.
The 17th iteration of the trees’ seasonal cycle gives the nymphs their final cue: it’s time to emerge
.
What is the life cycle of the 17 year cicada?
After the long 2 to 17 years, cicadas
emerge from the ground as nymphs
