Can a Tiny Brain Plan? Reconstructing a Predatory Detour inthe Jumping Spider Portia labiata

A 42-minute wild hunt by Portia labiata shows a route reconstruction that suggests planning, including avoiding a path half as long but more conspicuous to prey.

• Why it matters: Planning-like behavior is debated in invertebrates, and it is unclear whether lab observations translate to wild hunts where prey encounters can be lethal over long, complex routes.
• What they did: The study video-recorded the first fully documented wild hunt of any Portia species and used 3D reconstruction to map the spider’s 42-minute approach to an orb-weaving spider.
• The result: The reconstructed route suggests P. labiata may have evaluated alternatives, choosing a longer but less conspicuous detour to the prey’s sensory systems.
