Imature stages of the Banana fruit caterpillar, Tiracola plagiata (Walker, 1857) and its close relative, Tiracola aureata Holloway, 1989 are described and illustrated. We revealed the following four facts. 1: The sixth instar is estimated to be the last instar larvae in both species based on the width of head capsules. 2: Morphologically they are distinguishable in the third to sixth instar larvae, but not distinguishable in the eggs, first to second instar larvae and pupae by our study. 3: Both species are polyphagous. 4: Some of the formerly known host plant records of T. plagiata should be excluded because they are revealed to be the hostplants of T. aureata.

描述并举例说明了香蕉果毛虫蒂拉科拉·普拉吉塔（Tiracola plagiata）（Walker，1857）及其近亲蒂拉科拉·奥瑞塔·霍洛韦（Tiracola aureata Holloway ）的生长期。我们揭示了以下四个事实。1：根据头壳的宽度，第六龄的幼虫估计是这两个物种的最后龄幼虫。2：从形态上看，在我们的研究中，它们在第三至第六龄幼虫中是可区分的，但是在卵，第一至第二龄幼虫和p中是不可区分的。3：两个物种都是多食性的。4：一些的前身寄主植物记录T. plagiata应被排除在外，因为他们发现是的hostplants T. aureata。
