Abstract

Previous phenological analyses of GBIF records ignored data biases and produced misleading results. Here we demonstrate how data sufficiency and methodology affect inferred latitudinal patterns in lepidopteran phenology, highlighting the importance of spatiotemporal data aggregation decisions. Results indicate later and/or shorter flight period phenology at higher latitudes is common.
