| Cicadas do not possess special defensive mechanisms -- they do not
sting or bite. The ovipositor (which some may mistake for a stinger) is
used only for laying eggs and the mouth parts are used only for feeding
on twigs; thus, periodical cicadas can hurt you only if they mistake you
for a tree branch!"
University of Michigan
After
emerging from the ground, the cicada climbs up a tree or shrub
to
shed its shell. It makes an opening in the back of the shell
then crawls out leaving the shell attached. If it hasn't become a bird
snack by now, it dries it's wings then goes about the business of
drinking and
making babies.
When approached, a cicada will simply fly away. If handled, both
males and females struggle to fly, and males make a loud defensive
buzzing sound that may startle but is otherwise harmless. Cicadas are
not poisonous or known to transmit disease."
University of Michigan Periodical Cicada Page. It is the male that
makes all of the noise.
"After mating, adult female cicadas use their blade like ovipositor
to make
long openings in new growth sections of tree branches. A female
usually
lays
20 to 30
eggs in each opening, and there can be several egg "nests" per
branch. During her short adult life stage, each female lays
approximately 600 eggs. The eggs take six to eight weeks to mature then
the nymphs drop to the ground and immediately begin their descent into
an underground world."
John Folz University of Florida
"Eggs
hatch into
nymphs, which drop to the ground and burrow into the soil, where
they suck juices from roots of trees and shrubs. Depending upon the
species, cicada nymphs remain underground from 1 to 17 years, then
emerge."

We are expecting the "adult
periodical cicadas, Magicicada spp., they are sucking insects,
about 1.5-inches long, that appear from May to July. They are most
numerous in the last two weeks of May and first week of June. They are
black and have reddish-orange eyes and legs. Adults have clear wings
with orange veins that are held roof-like over their bodies."
