What it looks like

The Eastern Banded Tigersnail is a large terrestrial snail that ranges from 2.0 to 2.5 centimetres in size. It has a circular shell that is yellow to brown with a distinct light-coloured spiral band that is bordered by a darker band on either side. In Ontario, there is variation in the size, morphology and colour of the shells.

Where it lives

In Canada, the Eastern Banded Tigersnail inhabits moist old hardwood or mixed-wood forests. In Ontario, it has been found in Chinquapin Oak-Nodding Onion treed alvar, dry-fresh Hackberry deciduous forest, dry-fresh Sugar Maple-White Ash deciduous forest, and dry Black Oak woodland. These habitats are described as having either limestone bedrock with vegetative cover or sandy soil with a leaf litter layer.

Where it’s been found in Ontario

The Eastern Banded Tigersnail currently occurs on two islands in Lake Erie: Pelee Island and Middle Island. It was also historically found on Middle Sister Island, East Sister Island and North Harbour Island but now appears to be extirpated from these locations. It is unknown if this species still exists on Hen Island.

What threatens it

The greatest threat to the Eastern Banded Tigersnail on Pelee and Middle Islands is climate change that has increased the incidence of droughts, severe storms with flooding and temperature extremes. Other threats include trampling, competition with invasive terrestrial snails and slugs, predation from birds, and the alteration of habitat by Double-crested Cormorants.

Actions we are taking

What you can do

Report a sighting


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

Be a good steward

  • Private land owners have a very important role to play in species recovery. If you find Eastern Banded Tigersnail on your land, you may be eligible for stewardship programs that support the protection and recovery of species at risk and their habitats.

Quick facts

  • The Eastern Banded Tigersnail plays an important role in litter decomposition, nutrient cycling and soil building processes.
  • In the winter, individual snails seek moist refuge including snow cover to survive freezing temperatures.
  • Weathered shells of the Eastern Banded Tigersnail indicate that it has a long lifespan of 5 to 10 years.
