I had an enormous one land on me last week while enjoying the rocker on the porch. I almost came out of my skin (really, it must have been the size of a small bird...or chihuahua...or something). My 5yo looked at me with disdain and said, "It's only a butterfly...:"
Once we figured out how to get the deer and rabbits to leave our butterfly garden alone, we've also had a massing of butterflies not to mention hummingbirds. The garden is positioned in such a place that our guests are entertained by this fabulous display at breakfast each morning.
I have tons of those yellow butterflies here at my house too, I also have one of these black & blue butterflies, seems to only be one of these though. My Butterfly Bush is about 8ft tall, even after cutting it back in Fall!
For those unfamiliar with the butterfly bush, they drink the nectar and get a bit inebriated so you can gently put you palm beneath them and they will flutter around. it is fascinating!
I came home to three large black and blue butterflies today as well. I just love them. (Unlike the rhino beetle I saw the other day, not into Rhino beetles and didn't even know they lived around here!)
