    Abstract: PROBLEM TO BE SOLVED: To provide a fipronyl crystal allowing easy filtration and drying with less dust in a production procedure and a composition which is blended with the crystal, has formulation stability and is for insecticidal and parasiticidal mixtures.SOLUTION: A solid fipronyl is present as a monoclinic system having a center-symmetry space group C2/c, shows a specific reflection in an X-ray powder diffraction diagram recorded at 25°C by using Cu-Kα radiation rays and contains at least 85 wt.% of a crystal transformation I of fipronyl. A method of producing the crystal transformation I comprises dissolving a solid fipronyl different from the crystal transformation I in a solvent selected from one or more of alcohols, acetonitrile(AN), dimethylsulfoxide(DMSO), one or more of benzene derivatives, etc. and crystallizing from the resultant solution. When the solvent is AN, crystallization is carried out at 40°C or lower. When the solvent is DMSO, crystallization is carried out at 80°C or lower.
