To examine how predation pressure on forest insects varies with latitude and among forest strata.
Conducted field studies using six canopy cranes along a latitudinal gradient from 51°N to 34°S.
Evaluated predation rates on insects in both understory and canopy vegetation.
Analyzed the roles of bird and arthropod predators and their relation to prey abundance.
Predation is highest in the canopy at high latitudes and decreases towards lower latitudes.
Contrasting patterns show increased predation in the understory at low latitudes.
The findings challenge existing theories on latitudinal predation gradients.
