The invention belongs to the field of pharmaceutical chemistry and particularly relates to a novel dicyclanil medicine crystal form II suitable for medicine development and a preparing method thereof. The dicyclanil medicine crystal form II and the preparing method thereof are characterized by a N,N-dimethylformamide solvate of a dicyclanil medicine. The crystal space groups of the dicyclanil medicine crystal form II are a monoclinic system. One dicyclanil molecule and one N,N-dimethylformamide molecule are bonded through hydrogen bonds so as to form an elementary structure unit of the dicyclanil medicine crystal form II. A preparation process of the dicyclanil medicine crystal form II adopts the N,N-dimethylformamide as a solvent, and adopts a saturated-solution cooling crystallization method, wherein a solution is saturated due to volatilization by heating so that crystals precipitate in the process of the solvent cooling and volatilization. The dicyclanil medicine crystal form II is capable of preventing larvae of various flies, mosquitoes and fleas from developing to pupae or imagines, and the like, and is obviously improved in solubility, stability and bioavailability.
