Re: How far can a butterfly fly?

Daniel, Thanks soooo much for the link to the Nova series (Check it out: 6 Parts). I've never actually been too much of a butterfly fan, as the 'worm' stage eats my garden. But, this was sooo amazing.

I had no idea that it takes 2 mo to migrate to Mex de Canada, that they winter over here, that they then begin the trek back in the spring, mating in Texas (and finally dying, a total of 9 mo) and that it takes 3 generations each living only one mo to get back to Canada!!! Then, the 4th generation is the one that turns and flies back to Ca, living 9 mo. Incredible.

Nova says their winter habitat here in Mex is threatened, due to illegal logging. They must have these huge trees to winter on, as the heat from the trees keeps them alive through the winter. As the logging continues, fewer and fewer survive.

I'd had no interest in visiting this place here in Mex, but sure do now.....

Anyone seen it?

PS. Nova said a large group of the Canada butterflies fly across the Great Lakes, that when they get tired or bad weather occurs, they light on boats to rest. Seems a bit dubious, as how can they be sure to find one in bad weather? Anyway, I suppose they can fly from Tenacatita to our hills here.
