| Scientific Name: | Libellula forensis |
|---|---|
| English Name: | Eight-spotted Skimmer |
| Provincial Status Summary | |
| Status: | S4 |
| Date Status Assigned: | April 29, 2015 |
| Date Last Reviewed: | March 15, 2023 |
| Reasons: |
Relatively small range south of 51 degrees N from Vancouver Island east to the West Kootenay, however abundant where found in a variety of habitats including marshy ponds, lakes and wetlands including human made. Most of the range is in areas with high human population densities, therefore will have threats associated with this. |
