. Colonies of wild‐type Lucilia cuprina (Wiedemann) (Diptera: Calliphoridae) in our laboratory differed greatly in the degree of rhythmicity of their eclosion when exposed to light/dark cycles, constant darkness or constant light. Among colonies reared in the laboratory for thirty‐four to eighty‐eight generations and others for more than 360 generations, some were consistently rhythmic, others weakly rhythmic and others arrhythmic. One colony with arrhythmic eclosion was studied further. Arrhythmicity of eclosion in the colony was found to result from homozygosis of a recessive allele (ary) on chromosome 5. Adults from this colony were arrhythmic in spontaneous flight activity under constant darkness though rhythmic under light/dark cycles.
