The amount of cantharidin (Spanish fly) that the Neopyrochroa flabellata male presents to the female as a glandular offering during courtship represents only a small fraction of the total cantharidin the male accumulates systemically following ingestion of the compound. A major fraction of the acquired cantharidin is stored by the male in the large accessory glands of the reproductive system. At mating, the male transfers this supply, presumably as part of the sperm package, to the spermatheca of the female. The female in turn allocates the gift to the eggs. Eggs endowed with cantharidin proved relatively invulnerable to attack by a predaceous beetle larva (Coleomegilla maculata).
在求偶过程中，雄性扇角甲向雌性赠送的斑蝥素（西班牙苍蝇）腺体礼物，仅占雄性摄入该化合物后全身积累的斑蝥素总量的一小部分。雄性获取的大部分斑蝥素储存在生殖系统的大型附腺中。交配时，雄性将这一储备（可能作为精子包的一部分）转移到雌性的受精囊中。雌性则将这份礼物分配给卵。带有斑蝥素的卵相对不易受到捕食性甲虫幼虫（黄斑盘瓢虫）的攻击。
