The omnivorous leaftier has a wide host range and is known to cause damage to species from more than 20 plant families. Native parasitoid wasps manage this pest in natural and cropland settings. The first appearance of this insect in Oregon was noted in 1929 on strawberries and Dutch bulbous iris plantations near Portland. Soon, it was reported in Washington and California feeding on strawberry and flax grown for seed, respectively.
