I'm sure everyone has chased butterflies. They flitter here, flitter there; endlessly moving. I have found that a piece of duct tape strategically placed with the sticky side up, slows them down long enough to get a shot. Alright, I'm kidding. The tape has to be lapped so sticky is up and down. The most fun I've had with butterflies around the house was when we grew a passion vine. Passion vines for Gulf Fritillary's are like catnip to cats. They can't stay away. Grow the vine and they will come and come and come.
