Be vigilant for spotted lanternfly this fall. Thanks to Denise Beaton, crop protection specialist, Ontario Ministry of Agriculture, Food and Agribusiness, for bringing this issue forward. 

Note the Canadian Food Inspection Agency (CFIA) has not confirmed any established populations of spotted lanternfly in Canada. However, the agency continues to receive reports, directly and indirectly, of spotted lanternfly observations in various locations across Canada.

Below is the updated chart of sightings. 

The definition of a sighting is as follows:  Reports of spotted lanternfly in Canada that the CFIA is aware of, including those made on public reporting sites (for example, iNaturalist Canada, Facebook, etc.). CFIA has followed up on these, and could not confirm the report, as no spotted lanternfly specimen was found.

The definition of an interception is as follows: Live spotted lanternfly, confirmed by the CFIA, in contained situations (e.g. warehouse) with no evidence of release to the Canadian environment; and/or dead spotted lanternfly, confirmed by the CFIA.
