通过脱水和暴露在极低或极高的温度下，Polypedilum vanderplanki 幼虫的新陈代谢可以可逆地停止。幼虫在干燥时浸入液态空气或液氦中后发生变态。有的在102-104℃干燥1分钟后发生变质，有的在106℃3小时或200℃5分钟后暂时恢复。将幼虫浸入无水乙醇或纯甘油中干燥后回收。无水乙醇浸泡24小时后，1只幼虫发生变态，浸泡7天后全部幼虫暂时恢复。幼虫分别浸入甘油1、3、7天变态。一些幼虫在干燥保存10年后暂时恢复。它们能够耐受反复脱水：一只幼虫经过 10 次脱水后变态，水分含量约为 8% 或更低，每次脱水期间会间隔几天在水中进食。
Metabolism in the larva of Polypedilum vanderplanki can be brought reversibly to a standstill by dehydration and exposure to very low or very high temperatures. Larvae metamorphosed after immersion in liquid air or liquid helium when dry. Some metamorphosed after exposure to 102- 104[degree]C for 1 min when dry, and some recovered temporarily after exposure to 106[degree]C for 3 hour or 200[degree]C for 5 min. Larvae recovered after immersion in absolute ethanol or pure glycerol when dry. One larva metamorphosed after immersion in absolute ethanol for 24 hour, and all larvae recovered temporarily after immersion for 7 days. Larvae immersed in glycerol for 1, 3, and 7 days respectively metamorphosed. Some larvae recovered temporarily after being stored dry for 10 years. They tolerate repeated dehydration: one larva metamorphosed after 10 dehydrations to a moisture content of about 8% or less, each separated by several days in water during which it fed.
