"Upon chestnuts fall, the larvae chew their way out of the nuts and retreat into the ground. They immediately bury themselves several centimeters deep in the soil. Larvae may pupate in the soil for one season or for several years. The following July, they turn into pupae. The adult emerges and lives in the canopy of the chestnut tree." “橡實落下後，幼蟲咬出通道爬出堅果，撤退到地裡。他們立即將自己埋在幾釐米深的土壤中。幼蟲可能會在一個季節至幾年之間在土壤中化蛹。隔年7月，他們羽化並生活在橡樹樹冠。” https://en.wikipedia.org/wiki/Curculio_elephas
