巴克尔虫属毛虫。（鳞翅目：翼蝇科）有独特的食性，吃食肉毛毡苔植物（毛毡苔属）的陷阱叶。本研究观察了沼泽白僵菌在茅膏菜诱捕叶上的取食行为。并讨论了蛾类如何避免被诱捕器叶片捕获。在81.5%（66/81）的茅膏菜叶正面有腺毛的情况下，B。沼生菌幼虫在处理过的毛上舔食粘液并爬行。舔食粘液的频率显著高于其它行为，如吃腺毛、咀嚼腺毛基部而不进食以及遇到分泌粘液时不理睬。舔粘液使毛虫能够安全地在陷阱叶上移动，并防止腺毛弯曲。
Caterpillars of Buckleria spp. (Lepidoptera: Pterophoridae) have a unique feeding habit of eating trap leaves of carnivorous sundew plants (Drosera spp.). We observed the foraging behavior of Buckleria paludum on trap leaves of Drosera spp. and discussed how the moth species avoided being caught by trap leaves. In 81.5% (66/81) of encounters with glandular hairs on adaxial surfaces of Drosera trap leaves, B. paludum larvae licked mucilage and crawled on the processed hairs. The frequency of licking mucilage was significantly higher than the frequency of other behaviors such as eating glandular hairs, chewing bases of them without eating and ignoring when encountering secreted mucilage. Licking mucilage enables the caterpillars to move safely on trap leaves and prevents bending of glandular hairs.
