According to the local meteorologists, it has something to do with the drought. (Anyone who wants to set me straight on that, please do). Driving on 1604 in San Antonio, they are EVERYWHERE! I had to keep turning on my windshield wipers and washing smashed butterfly bodies off the windshield. Everywhere I go, they are fluttering about in great flocks...or herds...or swarms...or whatever you call a large group of butterflies. Really, it's kind of neat to see them. I'm surprised the birds aren't fatter.

Anyway...just curious. I was wondering if the rest of Texas or other parts of the U.S. were experiencing this butterfly phenomenon.

If you go from 10 to 20 degrees or from 50 to 60 degrees which one would represent the same amount of heat being gained? i am no math wizz obviously but it seems to me that celsius would have to be on a graduated scale and therefore the increase in heat energy would not be equal across all temperatures..in other words the jump from 32 to 33 would be a different amount of heat gain then the jump from 2 to 3 degrees...
