Mathematical Genes?
If a 13 year locust falls in love with a 4 year locust, would that make a 17 year locust? (13+4)
Or if a 17 year locust gets kicked out of the club and is demoted, would that make it a 13 year locust (17-4) or some other normal locust (17-x)?
As stupid as it may sound, is there a possiblity that the genes regulating emergence be additive or subtractive in their timing sequence IF (big if) locust species can cross-breed?

Root Sap
RAZD writes:
Last thing I remember reading was that the scientists believe that the flow of sap in the roots tells the nymphs when to emerge.
That doesn't make sense. A locust nymph embedded by a tree root will emerge "on time" with his buddies regardless of drought, flood or Scott's Turf Builder on the ground above?
The reason I mention it is that my neighbor's 180 acre farm includes 2000 taps in sugar maples to collect spring sap for processing into maple syrup. The flow of sap through the trees (and roots) is absolutely affected by weather patterns and temperature cycles. It does not seem to be related to calendar emergence cycles for a particular locust brood. And yet, out the little buggers come, right on, uh, "time".

Re: Signal
Why a signal, Redwolf? How about just an evolutionary niche that works.

"Well we can perch on the wires and watch cars slip and slide on their bodies and slam into telephone poles. Bring along a beetle sandwich. This should be fun."

Insectivore in the 15 year life span category?
Hi DBlevins.
So, we're looking for an insectivore with a lifespan under 17 years? A bird, reptile or small mammal? And does anyone know just how far back in history the 17-year locust goes?
