The Fascinating World of the Periodical Cicada
Believed
to be the longest lived insects in the world, periodical cicada
have extremely long life-cycles of 13-17 years. Unlike annual
cicada species which can be found every year, the periodical cicada
population are synchronized, so that almost all of them mature
into adults in the same year. This year's cicada population (17-year
Brood X) is one of the largest. Due
to their long life cycle underground and synchronous emergence,
they escape natural population control by predators, so when they
do emerge, they do so in overwhelming numbers, forming much denser
aggregations than those achieved by most other cicadas.
Not to be feared though, they are completely harmless to humans
or animals and do not bite or sting defensively. Quite a remarkable
natural event, regarded by many but a noisy nuisance by others.
Nevertheless, their existence above ground will only be a short
one. . . about 4 weeks. That is, providing those that are not
eagerly devoured by birds, snakes, cats, dogs and other predators
will go on to complete their mission of mating and laying eggs
before their demise. After
the eggs hatch, the tiny nymphs, scarcely any larger than fleas,
drop from the trees digging their way back into the earth where
they will spend the next 17 long years starting this whole process
all over again and making their next debut around 2021.
Periodical cicadas belong to the genus Magicicada and found in
eastern North America. The phenomenal emergence takes place in
fifteen states: GA, DE, IL, KY, IN, MD, MI, NC, NJ, NY, TN,OH,
PA, WV and VA.
