Sedentary habit of S. FL. lep populations - surprising?

[Hilton, Rob]

Actually many island birds loose their ability to fly!  They all have wings (however vestigial).

James, I don't think it's surprising at all that the P. agarithe population
in south Florida would be sedentary. Basically, if you were surrounded on
three side by near certain death (the Atlantic Ocean) you'd be sedentary
too! 

Over time, many island dwelling birds lose their wings. 

Similarly, I believe that I read that a new insect (naturally) introduced to
a Hawaiian Island is (far?) more likely to come from either Asia or North
America, both over 3,000 miles distant, than from any of the other Hawaiian
Islands that might be just a few hundred miles distant. Mike Quinn

I agree that it is likely P. agarithe.  Surprisingly, however, P. agarithe 
in Florida appears to be very, very sedentary with records for even N. 
Florida being scarce.  P. agarithe in Texas, however, is a well known 
wanderer.  I have records for the Kansas City,  MO and Lawrence, KS area 
(several) and I know it gets farther north sometimes in the fall.  I have a 
tendency to attribute northern strays, even in the east, to the Texas 
populations and not the Floridian, though this is *pure conjecture* on my 
part.  <snip>
