Belonochilus numenius
Sycamore Seed Bug, American Sycamore Seed Bug
Belonochilus numenius is a monotypic seed bug in the family Lygaeidae, native to North America and invasive in Europe since 2008. The species completes its entire life cycle on seed balls of Platanus species. It has spread rapidly across Europe through plant trade and wind dispersal, reaching 17 countries including a widespread distribution in North Macedonia by 2019. High population densities can cause nuisance aggregations in urban areas, though it is not considered harmful to host trees.

It is known from a restricted range in the eastern United States. The species completes three generations annually and is tightly associated with American sycamore as its sole documented host plant.
