1 INTRODUCTION Many phytophagous insects are host–plant specialists (Bernays & Chapman, 1994). If insects are to expand or shift their host plant diet, they must be able to recognize a new host plant as food, survive, and reproduce when feeding on it (Rausher, 1983). Host range expansions can occur through bottom-up forces due to host plant availability, detectability, and suitability for the insect species (Miller, 2008; Vidal & Murphy, 2018).
