Although Spotted Lanternflies have so far been confirmed only in six southeastern Michigan counties, they are certainly on the spread. This relatively new invasive pest has been in the United States since 2014 when it was found in Pennsylvania.

They do not bite or sting, but they can damage plants. They exude a sticky substance called honeydew, which attracts other insects such as wasps or bees. The honeydew can also mold.

A large infestation of them can restrict the ability of plants to photosynthsize. Of particular concern are vinyards.

Watkins Glen, in western New York, is in the heart of wine and fruit country. The Finger Lakes Land Trust is trying a novel approach to control the pests. The lanternflies came from Asia, as did the invasive Ailanthus, or Tree of Heaven. This tree is the primary food source of the lanternfly larvae.

Tree of Heaven is being agressively removed from the park with a few exceptions. A few male trees (Tree of Heaven has male and female trees) are being allowed to live, but are being injected with an insecticide that will kill the lanternfly larvae.
