I
noticed some shiny egg masses wrapped around the twigs of our biggest
peach tree this winter, but I left them in place since I didn't know
what they were. Sunday, tiny tent caterpillar webs began
radiating out from the egg masses. Bad news!
If you live east of the
Rockies, you've probably seen the tent caterpillar before, even though
you may not have known what it is. The caterpillars live inside a
spiderweb-like tent of white silk that can reach about a foot in
length, easily visible around the limbs of wild black cherries as you
drive down the highway. Tent caterpillars are voracious eaters
and can defoliate entire trees in a season.
Although wild black
cherries are their favorite food, tent caterpillars enjoy pretty much
every fruit tree you'd plant in your yard. They like apples,
pears, cherries, plums, and peaches. Large orchards spray
chemicals to kill tent caterpillars, but on the backyard scale they're
extremely easy to pick off the branch either in the egg stage or soon
after the caterpillars hatch. And our hens want you to know that
a web full of tiny caterpillars is a very tasty treat.
