Key Points

This research aims to understand how web type and thread tension influence prey-catching response speed in the spider Octonoba sybotides.
Examined the response speed of spiders to small and large flies based on web type (linear vs. spiral stabilimenta).
Increased the radial thread tension to assess its effect on response speed.
Focused on food-deprived and food-satiated spiders' web constructions.
Spiders showed faster responses to flies on spiral webs compared to linear webs, regardless of energy state.
Increased radial thread tension resulted in response speeds comparable to those on spiral webs.
Web construction varies based on the spider's energetic state, enhancing capture rates for smaller prey when hungry.

We only have this paper's title and publication details.

Examines how web type affects prey-catching speed in spider species, suggesting feeding state impacts response.
