Discussion Nocturnal. This burrowing snake is seldom seen on the surface except in the evening following heavy summer rains. It is not frequently found in damp soil under slabs of rock, logs, or other surface debris. In farming areas it is sometimes uncovered and eaten by chickens scratching through barnyard soil for worms. It defends itself by coiling and writhing about, smearing cloacal fluid over its body. Eats termites, ants, and ant pupae.
