Why we care: Spotted lanternfly is an invasive planthopper that causes damage directly by sucking sap from host plants, and indirectly due to mold that grows on honeydew excretions that can inhibit plant growth and cause death.
What is at risk? Spotted lanternfly poses a great threat to the fruit, hops, nursery, landscape and logging industries. Some fruit hosts include apples, plums, cherries and grapes. Tree hosts include oak, willow, maple and sycamore.
The threat: Spotted lanternfly populations are known to be present in areas of Pennsylvania and several other states. Egg masses are difficult to identify and can be transported to new areas on outdoor furniture, vehicles or other objects.
What could happen in Michigan? Spotted lanternfly has the potential to greatly impact the grape, hops and logging industries. Early detection is vital for the protection of Michigan businesses and agriculture.
