 | Bamboo Lappet Caterpillars Crawling on the Snow 雪面のタケカレハ（蛾）幼虫 Lots of hairy caterpillars of the bamboo lappet moth (Euthrix albomaculata directa, family Lasiocampidae) were spotted on the virgin snow. Some were crawling slowly on the icy snow, while others were just sitting still (for sunbathing?). Don't touch them with your bare hands! Their toxic hairs can cause skin inflammation. They overwinter in the larval form, when they exclusively feed on evergreen leaves of Poaceae grass such as the bamboo. Early-December 2008 in Japan. picasaweb.google.co.jp タケカレハは幼虫の段階で越冬しますが完全に休眠することは無いようです。冬も雪の上を歩く姿をよく見かけます。日光浴なのか食草（笹の葉など）を探し回っているのか。雪が降った翌日の晴れた午後に撮った11匹分の動画をまとめてみました（他に幾らでも居ました）。 動きも遅いのに雪面に無防備に全身を晒して鳥に食われたりしないのかと心配になります。毒毛による防御が有効なのかもしれないが、警戒色にしては中途半端な気がする。この毛虫に素手で触るとかぶれるので、くれぐれもご注意下さい。 2008年12月10日再生回数 513 |

 | Black Variation of Bamboo Lappet Caterpillar in Winter タケカレハ（蛾）幼虫の黒化個体 A hairy caterpillar of the bamboo lappet moth (Euthrix albomaculata directa, family Lasiocampidae) crawling on the surface of deep snow (4 deg C). Mid-January 2009 in Japan. It was approx. 18 mm long and blacker than the standard colouration (light brown; see the video response for instance). This species is known to overwinter in the larval stage. I've got the impression that more blackish larvae were often found in midwinter. I wonder if they are just a variant population or caused by a seasonal change for the overwinter survival. (melanized to absorb the scarce sunlight?) Other possibility is that maybe black ones are just different species, the reed lappet moth (Euthrix potatoria bergmani, family Lasiocampidae). Soundtrack (audioswapped): EN - Snow Dream 雪の林道にて。近縁のヨシカレハ幼虫と迷ったのですが、タケカレハだと教えて頂きました※。私の気のせいかもしれませんが、根雪の後はこのような黒化個体が多い印象です（通常色は薄茶色）。越冬のための生理的適応で黒化したのだろうか（太陽熱を吸収するため）。それとも通常色の個体は淘汰されてしまったのだろうか。飼育するなどして確かめてみたいものです。 ※《追記》 やはりヨシカレハかもしれないとの意見も頂きました。老齢幼虫でないと見分けるのは難しいようです。腹面や腹脚も観察すべきでした。実は成虫を羽化させようと採集・飼育してみたのですが、多忙になり育てられませんでした。 2009年01月23日再生回数 429 |
