DeLong first reported Orientus ishidae from the United States in 1919; it was presumed to be an introduction brought into this country on nursery stock. DeLong made his first collection in New Jersey on Devil's Walkingstick.

Orientus ishidae causes some leaf damage to a number of tree species, including Apple and Honey Locust. Valley and Wheeler (1985) found that the damage was not serious. They were able to document no natural enemies of this species; earlier authors found occasional parasitizing by Dryinid wasp larvae.

In their south-central Pennsylvania study area Valley and Wheeler found nymphs most common in June, and adults most numerous in July.

The species' range takes in Ontario and Quebec and most states east of the Mississippi River; there are also records from some western states.

The orange band between the eyes (easily seen in a dorsal view) is a good field mark of Orientus ishidae.
