Species at risk by type

A list of species at risk for the selected Ontario region.


  • rusty-patched-bumble-bee

    Rusty-patched Bumble Bee (Bombus affinis)

    Status: endangered

    The Rusty-patched Bumble Bee gets nectar from flowers by biting a hole in the outside of it and sucking up the nectar with its tongue. This behaviour, called nectar-robbing, leaves marks on the flower than can help researchers detect the bees' presence in an area.

  • gypsy-cuckoo-bumble-bee

    Gypsy Cuckoo Bumble Bee (Bombus bohemicus)

    Status: endangered

  • hungerfords-crawling-water-beetle

    Hungerford's Crawling Water Beetle (Brychius hungerfordi)

    Status: endangered

    This beetle is likely a glacial relict, a species that survived from the ice age in an isolated habitat.

  • northern-barrens-tiger-beetle

    Northern Barrens Tiger Beetle (Cicindela patruela)

    Status: endangered

    Females lay about 50 eggs during early summer, placing each egg in an individual hole in the ground.

  • nine-spotted-lady-beetle

    Nine-spotted Lady Beetle (Coccinella novemnotata)

    Status: endangered

  • mottled-duskywing

    Mottled duskywing (Erynnis martialis)

    Status: endangered

    The mottled duskywing lives in some of the rarest ecosystems in Ontario, such as oak woodlands, pine woodlands and tallgrass prairies. Other butterfly species with similar habitats, such as the Karner blue, frosted elfin and eastern Persius duskywing, have mostly disappeared from Ontario and Canada.

  • rapids-clubtail

    Rapids Clubtail (Gomphus quadricolor)

    Status: endangered

    Larvae bury themselves under a fine layer of sediment and breathe through the exposed tips of their abdomens.

  • bogbean-buckmoth

    Bogbean Buckmoth (Hemileuca sp.)

    Status: endangered

    Unlike most buckmoths, which live in drier habitats, the Bogbean Buckmoth depends primarily on wetlands that support the bogbean, its preferred food source.

  • pygmy-snaketail

    Pygmy Snaketail (Ophiogomphus howei)

    Status: endangered

    Adult Pygmy Snaketails are rarely seen because they spend much of their time in the forest canopy.

  • aweme-borer-moth

    Aweme Borer Moth (Papaipema aweme)

    Status: endangered

    An Aweme Borer was found on Manitoulin Island in 2005 - the first sighting of this species in almost 70 years!

  • hoptree-borer

    Hoptree Borer (Prays atomocella)

    Status: endangered

  • hines-emerald

    Hine's Emerald (Somatochlora hineana)

    Status: endangered

    Hine's Emerald lives for three to five years, spending most of that time underwater as larvae.

  • riverine-clubtail

    Riverine clubtail (Stylurus amnicola)

    Status: endangered

    Members of the riverine clubtail's genus are referred to as hanging clubtails for their habit of hanging vertically (tails pointing downward) when perched on streamside vegetation.

  • lauras-clubtail

    Laura's Clubtail (Stylurus laurae)

    Status: endangered

    Laura's Clubtail was first recorded in Ontario in 1999.

  • frosted-elfin

    Frosted Elfin (Callophrys irus)

    Status: extirpated

    The Frosted Elfin is a poor flier, which, along with its dependence on lupine, may explain why its populations are isolated and scattered.

  • eastern-persius-duskywing

    Eastern Persius Duskywing (Erynnis persius persius)

    Status: extirpated


  • karner-blue

    Karner Blue (Lycaeides Melissa Samuelis)

    Status: extirpated

    The Karner Blue has a lifespan of about five days as an adult butterfly.

  • american-burying-beetle

    American Burying Beetle (Nicrophorus americanus)

    Status: extirpated

    American burying beetles are the largest carrion feeding insects in North America. These beetles have highly sensitive organs on their antennae that can detect the smell of decaying flesh three kilometres away.

  • yellow-banded-bumble-bee

    Yellow-banded Bumble Bee (Bombus terricola)

    Status: special concern

  • monarch

    Monarch (Danaus plexippus)

    Status: special concern

    Caterpillars store a toxin in milkweed plants they eat, making them poisonous to bird predators as adults.

  • west-virginia-white

    West Virginia White (Pieris virginiensis)

    Status: special concern

    This butterfly was officially listed as endangered by Ontario in 1977, but in 1990, after a review of its distribution and abundance, its status was changed to vulnerable (now special concern).

  • lake-huron-grasshopper

    Lake Huron Grasshopper (Trimerotropis huronia)

    Status: threatened
