![]() praefica has two overlapping generations per year. Within a crop, larvae often aggregate on a few plants where complete defoliation may occur. Young larvae can be found on terminal leaves and buds, whereas older larvae are usually found in plant debris on the soil. Larvae feed on many broad-leaved plant species, chewing large holes in leaves or fruit (e.g. More than 60 plant species or genera have been recorded as hosts: Allium cepa, Amaranthus, Antirrhinum, Arctium lappa, Beta vulgaris, Centaurea solstitialis, Chenopodium album, Convolvulus, Cosmos, Crataegus, Cucumis melo, Cucurbita, Dahlia, Daucus carota, Erodium cicutarium, Fagopyrum esculentum, Gossypium herbaceum, Gossypium hirsutum, Grindelia camporum, Helianthus annuus, Hosta, Ipomoea purpurea, Juglans, Kochia, Lactuca serriola, Lathyrus odoratus, Lens culinaris, Lupinus albus, Malus domestica, Malva, Medicago sativa, Melilotus officinalis, Mentha, Oryza sativa, Phaseolus, Phaseolus vulgaris, Pisum sativum, Polygonum, Prunus persica, Pyrus communis, Rheum rhabarbarum, Rubus allegheniensis, Rubus idaeus, Rubus parviflorus, Rubus vitifolius, Salix, Sambucus nigra, Setaria, Sinapis arvensis, Smilax californica, Solanum, Solanum lycopersicum, Solanum tuberosum, Sonchus oleraceus, Sorghum bicolor, Taraxacum, Trifolium, Trifolium cyathiferum, Tripleurospermum inodorum, Vigna unguiculata, Vitis vinifera, Zea mays. praefica is a polyphagous species which can feed on forage crops, fruit and vegetables, ornamentals, and weeds. North America: Canada (Alberta, British Columbia), USA (California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington). In Alberta, it is considered that it is probably not present all-year round, but that adults are migrating from further south during summer.
