Actually, the 17 year locust appears each year, just that every 17 years, a
bumper crop appears. Cicadas mainly like oak trees (especially Quercus alba,
the white oak). I thought that 1995 or 96 was the 17th year. (There is also
a three year locust, and several other species, I think.) The main effect of
the cicada is tip dieback in oak trees. They seem to like the fresh tips of
oak branches. I don't think you have to worry about the veggies.

In the summer of 1996, while moving from PA to NC to finish graduate work,
_all_ of the oak trees on highway 15 through Virginia had dead tips. It was
quite a sight. When I reached NC State, I asked a forest pathologist here,
who said it was the 17 year locust.
