Abstract Animals exhibit a variety of strategies to avoid predation; spiders are no exception. We explored whether web-building that differ in the architecture their webs morphologies or behaviors suggestive antipredator trade-off with degree protection offered by webs. Spiders build 3 types: more protected tangles and sheet-and-tangles, which three-dimensional (3D), exposed orbs, two-dimensional (2D), both without refuge. hypothesize whose offer greater protection—a 3D refuge—will be less likely armored brightly colored when compared these protections. collected data on 446 2 lowland tropical rainforest sites. show 2D web builders refuges tended (background contrasting) spiny (spiky), whereas those blend against background refuges. builders, other hand, were neither cryptic nor but drop out upon simulated predator contact. These results support hypothesis tend either through morphology behavior, suggesting between different types strategies.
