Many animals avoid predation using aposematic displays that pair toxic/dangerous defences with conspicuous achromatic warning patterns, such as high-contrast stripes. To understand how these prey work, we need to the decision-making of visual predators. Here gave two species jumping spiders (Phidippus regius and Habronattus trimaculatus) choice tests live termites had their back patterns manipulated paper capes (solid white, solid black, striped). For P. regius, black striped were quicker capture attention. Yet despite this increased attention, attacked at lower rates than either white or black. This suggests termite's contrast background elicits but internal body patterning reduces attacks. Results from H. trimaculatus qualitatively similar did not meet threshold for statistical significance. Additional exploratory analyses suggest attention aversion stripes is least partially innate provide further insight into played out during trials. Because rich diversity (over 6500 species) includes variation in natural history, toxin susceptibility degree colour vision, are well suited test broad generalizations about why work.
