Re: RE: Pests-Grasshoppers/Cicadas Invasion

Just wanted to mention that almost every year there is an emergence of
either 13 year or 17 year Cicadas.  Some broods are larger or more
widespread than others, and some cycles are worse than others.  I'd have to
look up which brood(s) are due where this year, but they are very
predictable.  There are stragglers that emerge a year or two early or late
too (keeps the broods somewhat mixed up that way).

Haven't seen the article mentioned yet.

Also, I believe it is now thought that there are 6 species of Cicada
involved, all very closely related.

Most Cicada species have a one or two year cycle, and are not nearly so
prolific as these black and red swarms; however, indeed, most parts of the
country do have Cicadas of some sort out and buzzing or clicking every
year, some large and loud, some small and not so loud.

As for grasshoppers, much less predictable.  One or two year life cycles
are normal, but some of the worst ones may have multiple broods each year.
In some species some of the eggs will wait extra years to hatch (a survival
mechanism).  It is sort of like the Farmer's Almanac; you can make
predictions, but really they are just guesses in the end.  One year there
can be few and the next millions, and visa versa.  Also, there are hundreds
of species, and each is a little different in behavior and requirements.
