The strength of biotic interactions is generally thought to increase towards the equator, but support for this hypothesis is contradictory. We explored whether predator attacks on artificial prey of eight different colours vary among climates and whether this variation affects the detection of latitudinal patterns in predation. The data set provides number of damage marks on each of 1320 plasticine caterpillars of eight different colours, which were attached to branches of woody plants and exposed...
