Chelymorpha phytophagica

Members of the genus Chelymorpha can be distinguished from other tortoise beetles by their rounded, convex body form and the structure of the elytral margin. The species C. phytophagica is recognized by its coloration and pattern, though specific diagnostic features separating it from closely related species require examination of morphological details. The subspecies C. p. luteata and C. p. phytophagica differ in coloration and elytral markings.

Associated with host plants in the family Convolvulaceae, particularly morning glory vines (Ipomoea spp.) and related plants. Found in habitats where these host plants occur, including disturbed areas, agricultural fields, and natural vegetation.

Central America and North America. Present in Middle America and North America according to distribution records.

Phytophagous, feeding on leaves of Convolvulaceae. Both larvae and adults consume leaf tissue of host plants.

• Convolvulaceae - primary host familyMorning glory family plants including Ipomoea species

Herbivore on Convolvulaceae. Like other Chelymorpha species, may sequester alkaloids from host plants for chemical defense against predators.
