Field observation on predation of an orb web spider (Araneae: Araneidae) by the corinnid sac spider, Corinnomma severum (Araneae: Corinnidae)

Abstract

of web-building spider reported in this paper is only one of the versatile predatory tactics of C. severum , as has been reported in N. soloripes which forages prey by cursorial hunting and web-building, as well as by web-invading (Jackson & Poulsen 1990). Further field studies and laboratory experi ments are needed to reveal the prevalence of araneophagy in corinnid spiders, and how they specialize in eating spiders. Abstract ― In this short paper, we report the predation of an orb-weaving spider Neoscona sp. (Araneae: Ara -neidae) by a corinnid sac spider Corinnomma severum (Araneae: Corinnidae) from Thailand. To the best of our knowledge, this is the first report of predation of web-building spider by a spider of the genus Corinnomma observed in the field.
