Accidental twins in a monembryonic insect.
A grasshopper egg was found containing two embryos that were both males and contained one B chromosome. Their development was delayed in comparison with that of the untwinned embryos from the same egg pod but their morphology was apparently normal. The possible mechanisms causing this unusual phenomenon are discussed. Key words : twins, twinning in insects, grasshoppers, Eyprepocnemis plorans.
