A terrestrial animal belonging to the family Campephagidae, class Arachnida, order Araneae, phylum Arthropoda. This yellow spider is 12 mm long for females and 10 mm long for males, and is known in some regions as Kuchiguro, due to its prominent black upper jaw. It usually dwells on silver grass leaves folded into a rice dumpling-like shape. When the eggs laid in the dwelling in early September hatch, the baby spiders are known to devour the mother's body. This spider is also the most poisonous of all spiders in Japan, and if you are bitten, you may experience fever, swelling, pain, and chills for several days, depending on your constitution, but the poison is not fatal and you will eventually recover. Antihistamines are used as a treatment. Similar species to this one include the Yamato Komachi spider, the Asinaga Komachi spider, and the Yasakomachi spider, but the baby spiders of these spiders do not eat their mothers. [Takeo Yaginuma] Because the upper jaw is black, it is also called Kuchiguro in some regions. It is the most poisonous spider in Japan. It is also known that the hatched spiderlings eat the mother spider's body. Body length is about 12 mm for females and about 10 mm for males.

節足動物門クモ形綱真正クモ目フクログモ科に属する陸生動物。体長雌12ミリメートル、雄10ミリメートルの黄色のクモで、上顎(じょうがく)が黒くて目だつので、地方ではクチグロという所がある。普通、ススキの葉をちまきのような形に折り曲げて住居としている。9月初旬に住居内で産まれた卵が孵化(ふか)すると、子グモたちは母グモの体を食い尽くすことで有名。またこのクモは日本産のクモ類でもっとも毒性が強く、かまれると、体質にもよるが数日間発熱、腫脹(しゅちょう)、疼痛(とうつう)、悪寒の症状を呈することがあるが、毒性は致命的ではなく、やがて治癒する。治療法としては抗ヒスタミン剤が用いられる。本種と似た種類にヤマトコマチグモ、アシナガコマチグモ、ヤサコマチグモがいるが、これらの子グモは母グモを食べない。 [八木沼健夫] 上顎が黒いため、地方によってはクチグロともよばれる。日本産のクモ類でもっとも毒性が強い。孵化した子グモたちが母グモの体を食い尽くすことでも知られている。体長雌約12mm、雄約10mm。フクログモ科©Shogakukan"> カバキコマチグモ ©冨田百秋"> クモのおもな種類(1)徘徊性〔標本画〕 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
