A "found foliage" film composed of insects, leaves, and other detritus sandwiched between two strips of perforated tape.
You could say Brakhage puts the “anima” back into animation, reanimating the dead, painstakingly affixing the remains of dead insects, leaves and the like onto the film strip, and feeding it through the projector back to life. Of course, the principle of film projection is the illusion of life through light, with the audience gathering to watch like moths attracted to a lamp: the beauty of Mothlight is the way Brakhage evokes the moth not through cartoon mimicry, but by the fragile sensation of its movement, batting against the screen, hurtling in descent. The effect is exhilarating and terrifying.
