Answer
New York, New Jersey, and Pennsylvania
The species *Hylaeus hyalinatus* serves as an example of how the genus continues to spread globally, often facilitated by human activity, resulting in its introduction to new geographic regions. Documented occurrences of this species, which is not native to the area, have been officially recorded within the Nearctic region in several eastern states. Specifically, its documented presence includes locations in New York, New Jersey, and Pennsylvania. Although it is now geographically classified within the Nearctic region due to these introductions, its true origin lies externally to the Americas.
