    Sycamore Seed Bug - (Belonochilus numenius)

    Newly introduced to Europe, the Sycamore Seed Bug feeds on the seeds of its namesake and may become a pest in urban areas.

    Picture of Sycamore Seed Bug
    Staff Writer (10/4/2017): Native to North America, the Sycamore Seed Bug lives and eats on sycamore (also called plane) trees. True to their name, they feed on the trees seeds, which ruins the fruit around it and limits the spreading of fertile seeds to other areas. How they arrived in Europe is unknown, but they have been noticed in numbers in parks and walkways lined with plane trees. They may become a nuisance over time, creating a need to spray trees. They are able to survive cold winters as eggs, though in warmer parts of their range, they may take shelter under the bark of their host tree.

    Adults are active from mid-spring through autumn and 3 to 4 generations can be produced in a single year.
