An exotic caterpillar called the golden twin-spot moth, Chrysodeixis chalcites, is present in some Canadian greenhouses. It is a tropical species but can of course overwinter in greenhouses throughout the world. It feeds on many plant species including tomatoes, cucumbers, and peppers. It is not confirmed in the US so don’t panic just read up on the biology and identification and keep alert.

I am broadly interested in the ecology and management of arthropod pests. Herbivorous arthropods cause extraordinary damage to plants in agricultural, urban, and natural ecosystems. Understanding interactions between pests and their environment, plant hosts, and natural enemies can improve management practices and reduce pesticide applications.
