| Calling
All Females
What has two pairs of wings, six segments
to their abdomen, three eyes and a three-jointed beak? Oh, and it can be
heard ¼ of a mile away when calling their ladylove.
It's the "common" cicada, which has a drum-like
covering on its stomach, that vibrates to make the noise that attracts
females. The "drumming" as it's called, varies in tone and intensity, according
to the temperature, and time of day. If the temperature drops too low,
the cicada is stuck where they are, with a system too sluggish to fly.
On the other hand, they are free flying in temperatures as high as 115F.
North America boasts 100 of the 1500 known
species worldwide. The males perch in treetops over the summer, or June
to September, and produce various clicks, buzzes and drummings, to attract
mates. Females will lay their eggs in the splits along a branch (which
damages many bushes and plants), and when the young hatch, the larvae drop
off and burrow into the ground for various periods.
In one of those odd quirks of nature, the
cicada comes in various "time periods", or life cycles. Some will stay
underground for only a year, while the species that stays dormant for 17
years, is believed to be the longest living insect in the world, next to
female termites.
