クリの葉を巻いた揺籃(切り落とさないタイプの片裁型揺籃)を枝から採集して飼育。湿らせるのを忘れた揺籃が容器内で枯れてしまったので身を案じたが、無事に成虫が羽化してくれた。これはいわゆる並オトシブミかな。首が長くて円錐状なので♂。なぜか未だ飛行が覚束ないようです。離陸をスローで見ると翅を広げながら必ず中脚を持ち上げます。
I got a rolled-leaf cradle from the chestnut tree (Castanea crenata), from which emerged an adult male of the leaf-rolling weevil (Apoderus jekelii). Somehow, he was not good at flying yet. (His maiden flight?) Slow-motion revealed that he rose his mid-legs before every takeoffs.

That is one funky looking Weevil - looks like an insect version of a Giraffe!

this is the commonest species of leaf-rolling weevils in jpn.
this was a male, judged from its long neck.
i have heard that males fight each other by neck wrestling to obtain females.
to see a more giraffe-like weevil, check out my vids;
