There have been several earlier reports of the species in Texas and Arizona. In Costa Rica the larva of this species feeds on mistletoe and looks a great deal like the berries (see Janzen & Hallwachs ACG website). Limacodidae are too poor at dispersing to have strays. Also, it is probable that this is a female (the antennae of females of this species are bipectinate like the males: the view of the abdomen in the other photo from the same location looks more like a female as well).

How big is this wonderful creature? I've never seen anything like it, it's beautiful!
