The 13 year Cicadas began arriving at our farm a week or so ago. They are everywhere! Thankfully, they only stay around for a matter of weeks. I actually like the sound of them singing for some reason…I think it reminds me of summers growing up. And I chose the wrong year to plant six new apple saplings. Cicadas love to lay eggs in the branches of young fruit trees which can kill them.

underground by feeding on tree roots. They emerge
from the ground when the soil temperature where
they live reaches 67 degrees. Four or five days later,
the males begin their “chorus” and mating begins.The females then begin laying eggs in the limbs of
smaller trees, as many as 400 to 600 eggs at a time.
After six to seven weeks the eggs hatch and the
“nymphs,” as they are called, drop to the ground and
burrow into the soil where they remain for 13 to 17
years.
It is the laying of eggs that poses a danger to small
flowering and fruit trees. A female can make five to 20
slits in one branch to deposit her eggs. That causes
the branch eventually to wilt and die.

The time from emergence to death is approximately four to five weeks.
After that the cicadas die quickly.
It’s not uncommon to find hundreds of dead cicadas piled up under trees in early June.
When they die and decompose, the nitrogen in their bodies fertilizes the soil.
