What is spotted lanternfly?

This large planthopper is an invasive insect from Asia that uses its straw-like mouthparts to pierce the surface of a plant and suck out the sap. The insect feeds on a wide range of plants, but is particularly fond of grapes (both wild and cultivated), the “Tree-of-Heaven” and numerous other deciduous tree species.

What damage does it cause?

When the insect feeds, it can weaken plants and in some cases of repeated feeding, can lead to plant death on preferred hosts. When the inset feeds on trees, vines and shrubs, they excrete a sticky, sugary fluid (honeydew) that promotes the growth of unsightly dark, sooty mould that can also attract wasps.

Where is it found?

The spotted lanternfly is not known to be established in Canada, but officials expect to find it soon, since it is well established just over the border in New York, Michigan and Ohio. This pest has spread quickly throughout the north-eastern states; it is now present in 17 states.

Members of the public and the landscaping community are encouraged to look for this insect, especially near major transportation corridors, railway lines, shipping and receiving areas, and even hitchhiking on your vehicles or equipment.

What do I do if I see it?

Spotted lanternfly is a regulated pest in Canada, therefore, if you see it you must report it!

If you see it, try to take a picture (but they are very jumpy and hard to photograph!) or catch it, but most importantly – “See it? Squish it!” Make a note of where you found it, and what life stage you observed (egg mass, nymph, or adult).
