Make a Fruity MashIf you can't plant butterfly-attracting flowers, you can still bring butterflies to you by making a fruity mash that butterflies and moths can't resist. Mash any fruit with a sugar source (sugar, molasses, corn syrup, or honey) and let it sit for a few hours, then smear your mash on a surface in your yard that can be hosed off later. It’s best to put your mash in a semi-sunny area so it won’t dry out as quickly.
