Creating my butterfly feeder was quick, easy and inexpensive. I had much of what I needed on hand. A dollar store windchime with four attachments where the chimes hung was the perfect piece of mechanics for hanging a shallow container filled with Gatorade or boiled sugar water. (4 parts water to 1 part sugar)
No instructions needed, use what you have on hand. The secret lies in the wire and plastic container: a plastic dish scrubber. The butterfly can land on this and use his long proboscis to dine on the nectar. I created holes in the plastic dish with a hot ice pick.
When I added the wire for hanging I let the end curl upward. These make the perfect spear for rotting/old fruit. I was going to use a strawberry, but remembered they are heavily sprayed with insecticide. It is better to use fruit that is within a peel unless it is organic.
