Caper Butterflies

I heard on ABC Radio (yesterday) that millions of White (Caper) Butterflies from all over the State (Sth in Australia) were flying North. This occurrence hasn't been seen since 1974 and never in such numbers. The lines were running hot with the speculation of what it meant and people were asked to phone in with information to the Adelaide Museums entomology dept. Some people rang in saying it was like walking through a snowstorm.
