Culex pipiens

Also known as the “Common House Mosquito”, this species can be found throughout Canada. It is the main West Nile Virus vector. The larvae can be found in almost every type of environment, even in heavily polluted water.


Blacklegged Tick (Ixodes scapularis)

Also known as a “Deer Tick”, they are the main vector of Lyme disease in North America. In addition they can transmit a host of other diseases including babesiosis, anaplasmosis and Powassan virus.


Molecular Diagnostics

We routinely use molecular diagnostic tests to detect West Nile Virus, Eastern Equine Encephalitis Virus, Lyme Disease and Babesiosis.


Benthic Invertebrate Identification

Benthic Invertebrates (like this Caddisfly larvae) inhabit the sediments of lakes, rivers and streams, and can be used as indicators of water quality.


Ochlerotatus japonicus

This invasive species can be distinguished by the 5 gold stripes on its scutum. It was first detected in North America in 1998 and is now found throughout the province of Ontario.


American Dog Tick (Dermacentor variabilis)

Also known as a “Wood Tick”, commonly found in Ontario these species pose less of a risk to humans than Ixodes scapularis, however they are capable of transmitting Rocky Mountain spottend fever and tularemia.


Mosquito Larvae

Mosquito larvae inhabit a variety of stagnant bodies of water such as ponds, discarded tires, eaves troughs, rain barrels and catch basins. Many surveillance and control measures target mosquitoes at the larval stage.


Kick Net Sampling

This is one method used to collect benthic invertebrate samples from streams. It involves placing a net on the bottom of the stream and kicking the substrate, allowing any invertebrates to flow into the net.



Dragonflies are an essential component to Ontario’s food chain. Their presence indicates a healthy environment and they prey on a variety of insects at the larval and adult stages, including mosquitoes.


Passive Tick Surveillance

Testing blacklegged ticks collected from dogs and cats, can assist with surveillance, and monitor the spread of the Lyme disease.


Aedes aegypti

This mosquito is distinguished by its striped legs and silvery white lyre shaped marking on the dorsal part of its thorax. It is a vector of yellow fever, dengue fever, Chikungunia, West Nile Virus and Zika Virus.


Giant Swallowtail

Butterflies are valuable as a food source, and pollinators of plants. There are currently 3 species are extirpated, 2 species are of special concern and 1 species of considered endangered in Ontario.


Anopheles earlei

Anopheles are responsible for the transmission of malaria. The species in this picture does not transmit malaria, another species found in Canada – Anopheles quadrimaculatus– may potentially be a malaria vector.


Aedes albopictus

Also known as the “Asian Tiger Mosquito”, this species is distinguished by its stripped legs and silvery white stripe down its thorax. It is a vector of pathogens such as yellow fever, dengue fever and Chikungunia.


Larval Tick

Ticks in the larval stage are difficult to detect due to their small size, however they do not posses a direct risk to humans as they typically feed on small mammals such as mice and voles.
