Male Neopyrochroa flabellata have a natural affinity for cantharidin (Spanish fly). They are attracted to cantharidin baits in the field and feed on the compound if it is offered to them in the laboratory. Males that ingest cantharidin secrete cantharidin from a cephalic gland. Females sample secretion from this gland during courtship and mate preferentially with males that had fed on cantharidin. Cantharidin-unfed males can be rendered acceptable to females if cantharidin is added to their cephalic gland.
雄性新拟叩甲对斑蝥素（西班牙苍蝇）有天然的喜好。它们在野外会被斑蝥素诱饵吸引，如果在实验室中向它们提供这种化合物，它们就会以其为食。摄入斑蝥素的雄性会从头部腺体分泌斑蝥素。雌性在求偶期间会采集该腺体的分泌物，并优先与食用过斑蝥素的雄性交配。如果将斑蝥素添加到未食用斑蝥素的雄性的头部腺体中，它们就能被雌性接受。
