Carolinian Canada is working to help recover species at risk and their habitats. The Carolinian forests of southern Ontario support an amazing diversity of plants and wildlife, including many species at risk.To learn what you can do to help reduce the threat of invasive species, visit: ontario.ca/invasivespecies, and Invasive species such as round goby are a potential threat to the riverine clubtail.

You may be eligible for stewardship programs that support the protection and recovery of species at risk and their habitats.

Private land owners have a very important role to play in species recovery.

Volunteer with your local nature club or provincial park to participate in surveys or stewardship work focused on species at risk.

Photographs with specific locations or mapping coordinates are always helpful.

Report a sighting of an endangered animal or plant to the Natural Heritage Information Centre.

Where it’s been found in OntarioĬurrent records of the riverine clubtail in Ontario are from Big Creek and Big Otter Creek, two streams that empty into Lake Erie near Long Point. Adults hang vertically off leaves as they await prey flying by. After emerging, adults tend to move from riverbanks to the forest canopy to feed. Larvae often burrow in the river bottom and prey on small animals such as other insects. This dragonfly is found in and near streams and rivers with sandy, muddy, or gravely beds. Females have yellow patches along the sides of the abdomen. The abdomen is blackish with small yellow spots along the top and larger yellow spots on the sides near the tip. It has a prominent club at the end of its abdomen, and the front of its thorax (the part of its body to which its legs and wings are joined) has a distinctive three-pointed star. Riverine clubtail is a small, slender dragonfly about 5 cm in length.
