This is the Diaethria clymena, also known as the 88 butterfly for the black, red and white patterns on the backsides of their wings. Their front sides are black with a metallic aqua green to blue hue. 8 is my fav number!
As cute as this bunny is ~ if you decide to get a rabbit as a companion ~ do a lot of research first. They require much different housing, feeding & care than is generally believed ~ and they can be very expensive!
