I've been doing my own research, planning the species in my locale in order to
customize a butterfly garden at my new home.

According to my research to date, male butteflies feed at drying puddles of
water, and some species on feces (I'm not sure about carrion).  They derive
minerals and salts and other nutrients from these sources which are necessary
to enhance their ability to breed.  They spend most of their time either
lingering on a low hilltop or patrolling a territory, hunting for receptive
females.
