Pyrrhalta viburni (Paykull), a new landscape pest in the U.S., feeds exclusively on plants in the genus Viburnum. We measured leaf consumption and oviposition by adults in the laboratory using detached leaves and stems. Females consumed twice as much leaf area per unit time as males, and both sexes fed almost exclusively at night. Egg-laying was concentrated at night at well, but also occurred during photophase. In no-choice tests, adults fed on both preferred and non-preferred host species, but ate significantly more leaf area of host plants utilized more heavily in the field.
