A butterfly landed on my shoulder while working on my boat & stayed about two hours. Why?

Question

I never quit working; was in and out of my shop; stopped for water breaks; was using saws and grinders; and wasnt careful. Called my wife to check it out and take pictures and it simply watched me and showed no fear.

Answer 1

some butterflies are attacted to sweat, and they come to drink the sweat which is high in salt, ............ then just like some butterflies are attracted to the sweeet smell of flowers .... some butterflies are attracted to the smell of dead and decaying flesh .........
