Spotted lanternfly – Lycorma delicatula
The spotted lanternfly (Lycorma delicatula, Hemiptera: Fulgoridae) is an impressive and colourful insect native to Asia. It is not yet known to exist in Canada but is a potential threat to Canada's grape, fruit tree and forestry industries. Spotted lanternfly was added to the regulated pest list in 2018 in an effort to prevent its introduction from infested areas.
What to do
- It's important not to accidentally transport these pests into Canada, so if you're travelling or going camping in infested areas of the US, check your camper, trailer or RV before making the return trip
- Inspect things stored outside, including your vehicle and patio furniture
- Look closely at things like tarps, yard and garden items, and sports equipment (including the underside)
- Spotted lanternfly egg masses are laid in late summer. These egg masses can survive winter temperatures and hatch in the spring.
- If you think you have found the spotted lanternfly pest or egg masses in Canada, scrape them into a sealable container and immediately notify the Canadian Food Inspection Agency (CFIA).
If you think you have found a plant pest, report it to the CFIA.
