Original caption: "(A) Experimental setup to test how rain drops falling onto the pitcher lid affect ant capture. (B) Proportion of ant visitors to each pitcher surface that fell into the pitcher, under ‘dry’, ‘raining’, and ‘wet’ treatment condition, respectively. The interaction of pitcher surface and experimental condition was highly significant (P&lt;0.001)."
