This paper describes field-based observations of male-male agonistic behavior in a longlegged sac spider Cheiracanthium eutittha (Araneae: Cheiracanthidae). Males of the species exhibited a characteristic agonistic behavior, where two males hung from leaves with a dragline, with all of their long legs entangled with each other and pushed each other’s body aggressively. To the best of my knowledge, this is the first video-based report of male-male agonistic behavior associated with usage of elongated legs in this spider family.

アシナガコマチグモCheiracanthium eutitthaの雄間闘争を動画に基づき初めて報告しました。本種の雄は、葉裏や枝先から糸を引いてぶら下がった状態で互いの全歩脚を絡ませ合うという闘争行動を示すことが分かりました。オープンアクセス、動画つきです。
