$50 Reward for Cicadas

Hey folks, I just got this message from John Cooley, a cicada researcher:

Have I got a deal for you……..see the attached. We’re hoping to
mobilize the cicada fan club to see whether our local brood really
has gone extinct (I think it has- no sightings at last known patch in
1971, 1988, or 2005).

There’s more info about this on Cicada Central— I’ll also consider
some sort of a reward for significant collections of live M.
septendecim stragglers from the eastern part of Brood X, and I’ll
grant the full reward for XI specimens in the CT river valley of MA
and CT, as well as anywhere in RI.

So, if you find a Magicicada in those areas, and have proof, please contact John.

Cooley Reward.

Brood XI: Alive?

Filed under: Brood XI | Magicicada — Dan @ 11:29 am

It is possible that Brood XI is not extinct. Brood XI hasn’t been recorded since in 1950’s, however, David Marshall of the University of Connecticut “would not be surprised if there are small patches of them that have been missed since much of southern New England is not that densely inhabited”.

If you’re in the Connecticut, Massachusetts, or Rhode Island area this spring and you hear or see a Magicicada, please let us know.
