'Like magic': small emergence of cicadas thought to be extinct found in
New York

BOHEMIA, N.Y. (Reuters) - Dr. Elias
Bonaros, a cardiologist and cicada expert, thought the noise-making
insects - which emerge from the ground every 17 years - might not return
to his neck of the woods, New York state's Long Island, after very few
showed up in 2004.
But this week they came back.
Bonaros, 48, has always loved the bugs.
"I was about 5 years old and my father one day caught a cicada in the
summertime, put it in my hand, nature's natural noisemaker," he said in
Connetquot River State Park Preserve on Long Island east of New York
City. "It was really quite enhancing and entrancing, it was very
fascinating to me."
Bonaros missed the emergence on Long Island of the so-called Brood X
(pronounced "Brood Ten") in 1987, when he was 14, not looking for them
until after they had already emerged, mated and died. "It was
heartbreaking."

He was disappointed again in 2004, when small numbers of cicadas were
reported. "I went to Ronkonkoma," he recalled. "I drove around here and
... did not hear anything."
He wondered whether enough cicadas had survived and reproduced to
produce a brood this year.
As Bonaros walked around the preserve on Tuesday, he heard the distant
mating call of Brood X cicadas, 1-1/2-inch-long (3.8-cm) black insects
with iridescent wings and bright red eyes.
"Brood X appears to be very, very small" on Long Island, he said, but
added, "I'm glad they're not extinct. I'm glad a small population is
hanging on."
Billions of Brood X cicadas began emerging last month in 15 states, from
Georgia to Washington, D.C., and west to Indiana and Illinois. But none
emerged in New York state.
Entomologists were worried that the Brood X cicadas were extinct on Long
Island due to development, or birds "which prey heavily on the cicada.
There could be even possibilities of the spraying of pesticides,"
Bonaros said.

Ultimately, he said, scientists didn't really know
why the Brood X cicadas were disappearing from Long Island.
"There's a lot of fragmentation of the environment, a lot of
development, which if you pour concrete over a surface, that pretty
much kills the nymphs," he said. "The cutting down of trees and
development takes their food source away."
Cicadas live above ground as adults for about three weeks - just
long enough to reproduce before dying. They thrive in sunlit forest
edges, which often provide the warmer weather and younger trees most
ideal for them to lay their young.
Periodical cicadas burrow into the ground after hatching, some
digging as deep as 8 feet (2.4 meters) below ground. While
underground, the nymphs suck the sap from tree roots for
nourishment. After 17 years, they emerge and climb trees and shrubs,
where they shed their crunchy skins and harden into maturity.
The males make a cacophony of sounds in the treetops as they look to
mate. Once the cicadas mate, the females cut slits into tree
branches, where they deposit 400 to 600 eggs. The adults quickly
die, but the eggs hatch a few weeks later to restart the cycle.
This year's cicada class will bore into the ground and won't emerge
again until 2038.

"Hopefully they'll be able to find mates, produce, and 17 years from
now, you bet I'll be here looking for them," Bonaros said. "I will
be in my 60s."
