Environmental complexity in Heliconius butterflies

This dataset contains data from experiments described in the manuscript (submitted): Experience improves spatial foraging performance in a complex environment in Heliconius butterfliesThis dataset contains behavioral data from 80 Heliconius erato butterflies tested under two spatial environments: an open cage and a maze cage with internal mesh walls that constrained movement and visibility. Resource placement was identical between treatments. Butterflies were randomly assigned to cages and housed for 15–36 days across two experimental rounds. At the end of the housing period, individuals completed a navigation assay in both familiar and unfamiliar cages. For each trial, we recorded feeder success (yes/no), latency to reach the feeder (seconds), and final grid position. The feeder was unrewarded to control for olfactory cues.
