Why don’t the butterflies or moths fly right after emerging?
After the butterfly or moth emerges from its chrysalis/cocoon the abdomen is very fat. The butterfly or moth pumps fluid from the abdomen to the wings. The fluid fills the veins and the wings are shaped. It takes an hour for the wings to take shape. The wings then need to dry for about 2 hours before the butterfly can fly. If the wings do not expand properly or are injured when drying the butterfly will not fly!
