甲状腺毛毛虫（Calindoea trifascialis）在受到干扰时，会从第一腹节背侧开口的两个囊状腺体中释放出防御性分泌物。幼虫有两个臂状突起，在腺体开口前面从身体向外突出。当幼虫激活其腺体时，这些“手臂”会被分泌物弄湿，似乎专门用于管理液体。分泌物的主要成分是扁桃腈（一种氰基化合物），但液体还含有其他潜在的抑制物，包括苯甲醛、苯甲酸、(E,E)-α-法呢烯和 3-甲基丁基-3-甲基丁酸酯。在该物种的原产地越南进行的实地测试表明，这种分泌物可以防止蚂蚁。
The thyridid caterpillar,Calindoea trifascialis, when disturbed, emits a defensive secretion from two sac-like glands that open dorsolaterally on the first abdominal segment. The larva has two arm-like protuberances that project outward from the body just in front of the gland openings. These "arms", which are wetted by secretion when the larva activates its glands, appear to function specifically for administration of the fluid. A primary component of the secretion is mandelonitrile, a cyanogenic compound, but the fluid also contains other potential deterrents, including benzaldehyde, benzoic acid, (E,E)-α-farnesene, and 3-methylbutyl-3-methylbutanoate. Tests done in the field in Vietnam, where the species is native, showed the secretion to be protective against ants.
