Abstract
We report laboratory observation of siblicide with hatching asynchrony in the passalid beetle Cylindrocaulus patalis. Parents construct a breeding gallery in rotten logs and show complex care of offspring, including provisioning. Clutch sizes are extremely small, and only a single offspring is raised in a colony in each breeding season. We introduced field-collected colonies into an artificial gallery and recorded the behaviour of colony members. Eggs hatched at 2- to 10-day intervals in each colony. Fatal fighting invariably occurred among the larvae soon after hatching of the junior larva, and a single larva, usually the senior one, survived.
