Get out your earplugs - the 17-year
cicadas are back!
Unlike the common cicada which appears each year during the dog days of
summer, the 17-year variety spends most of its time underground. The batch
now emerging was last seen in 1979, when female
cicadas laid their eggs in tree limbs. The eggs hatched and fell to the ground
and the young nymphs burrowed below the surface, some as deep as eight feet,
where they sucked the sap of tree roots for nourishment.
Although scientists still haven't a clue as to how, these cicadas can
count yearly cycles and after 17 years the insect burrows back to the surface,
climbs into trees and shrubs and starts the whole process over again. Once
above ground they shed their skins and harden into maturity. And they
mate, and mate and mate!
It's this ritual that makes them not only
fascinating, but annoying. The males emit a metallic whining sound to attract
a female. And because the
insects cluster into large colonies the sound can be overwhelming. One insect
alone can be heard a quarter of a mile away. A colony can drown out the sound
of a lawn mower.
The cicadas sing from dawn to dusk, which can not only cause headaches
but can also drain the nerves of anyone living in spots where the insects have
chosen to gather. The only reprieve from the noise comes when the insects die,
which is about two weeks after they emerge from the ground.
Before they die, however, the females cut slits in tree branches and lay
anywhere between 500 and 1,000 eggs, which hatch within a few weeks.
Oh, and one other problem -- the stench from decaying cicada carcasses has
been compared to Limburger cheese.
T
he thick black bugs, which measure about one-and-a-half inches long, have
iridescent wings which seem too small for their bodies and bulging red-orange
eyes. And they're considered a delicacy for birds and humans alike. Rumor has
it they're especially good (minus wings and legs) battered and deep-fried or
stir-fried with vegetables.
The 17-year cicadas are found in the United States east of the Great
Plains. New York is expected to see its fair share, especially through the
Hudson Valley into upstate. Colonies are expected from New Hampshire down
through North Carolina.
And don't worry - the insects don't bite or sting. Just be ready with
some good earplugs if you live in a wooded area where the insects decide to
take up residence.
