The invention discloses a method for subcritical fluid extraction of hermetia illucens larva oil, which is characterized by comprising the following steps: (1) material preparation: collecting hermetia illucens larvae, inactivating the hermetia illucens larvae in boiling water, drying, removing impurities, and crushing; putting the prepared hermetia illucens larva powder into a filter bag, and putting the filter bag into an extraction tank; (2) subcritical fluid extraction: injecting a solvent n-butane into an extraction tank, and extracting the material to obtain an extract; and (3) after the operations of extract separation and solvent recovery extraction are finished, separating hermetia illucens larva oil and degreased hermetia illucens larva powder in the extract through reduced pressure evaporation, and recovering the solvent. The method solves the problems of low extraction rate and organic solvent residue. 本发明公开了一种亚临界流体萃取黑水虻幼虫油的方法，其特征在于，包括以下步骤：(1)备料：收集黑水虻幼虫，在沸水中进行灭活后，烘干除杂后进行粉碎；然后将制得的黑水虻幼虫粉放入滤袋中，投入萃取罐中
