Maybe now the discussion should turn to the question of what nutritional benefits do 
butterflies obtain from animal excrement?  Have there been any studies about this? It seems 
likely for optimum health, many butterflies need more than sugar water (i.e. flower nectar) 
alone. Is there a practical way to incorporate some of these excrement nutrients in home 
butterfly nectar mixes?
