How much do #butterflies weigh? Dr. Paul Opler states, "I have some information on butterfly #weights but not exact weights for the #largest and #smallest butterflies. However, I can make #pretty good guesses. I have weights ranging from 0.3 gram for a large #swallowtail to 0.04 gram for a small butterfly called the elf.
