The study recently published by Tiit Teder in Oikos (https://doi.org/10.1111/oik.07119) indicates ecological limitations to multivoltinism in lepidopterans. There is only a limited phylogenetic signal in voltinism distribution across the lepidopteran tree of life. Obligately univoltine species dominate among egg and adult overwinterers (life-histories typical of so-called spring-feeders), whereas species with capacity for multiple generations prevail among pupal overwinterers. Multivoltinism is also infrequent among species feeding on grasses. This information can help to predict species responses to the ongoing climate change.
