Amphisbaena alba, also known as the red worm lizard or less commonly as the white or white-bellied worm lizard, is a species of amphisbaenian in the reptilian order Squamata. Despite the large geographic range that this species covers, little is known about its ecology due to its secretive habits. A. alba has a diverse diet ranging from plant material to small vertebrates. Numerically, beetles, ants, and spiders compose the majority of their diet; however, ants, insect larvae, and beetles are ingested to satisfy a larger volume.
