The Cabbage White is found all over the USA but NOT in southern FL or TX. As it’s name suggests it does use Cabbage as a food plant for it’s caterpillars and consequently can be seen as a garden pest. It is big and white with black/gray fore-wing tips and 1 or 2 spots on the fore-wings upper surface. The rest is all white. It is seen in the Big Bend Area of FL but it is not a common butterfly, farm areas are good to try to find it.
