The larvae feed on a wide range of broad-leaved herbaceous plants, including Brassica oleracea, Trifolium, Fabaceae, Allium, Pisum sativum, Capsicum, Solanum tuberosum, Nicotiana, Solanum lycopersicum as well as various weeds.
They have a very broad host plants range, mainly broad bean (Vicia faba), green bean (Phaseolus vulgaris), pea (Pisum sativum), potato (Solanum tuberosum), tomato (Solanum lycopersicum), aubergine (Solanum melongena) and cucumber (Cucumis sativus), as well as sugar beet (Beta vulgaris) and cotton (genus Gossypium).
The larvae are considered an agricultural pest on Arachis hypogaea, Chamaecytisus prolifer, Lupinus nanus, Medicago sativa, Pisum sativum and Glycine species.
