While all mosquitoes are annoying, not all are created equal. Here in Essex County, including Amherstburg, several species thrive, each with their own preferences, behaviors, and potential health concerns. Understanding the common culprits buzzing around your yard can help you better protect yourself and your family.
1. Cattail Mosquito (*Coquillettidia perturbans*)
- Description: Known for their particularly painful bite and their ability to emerge in large numbers. They are medium-sized, with a mottled appearance on their wings and legs.
- Where They’re Found: Their presence is closely tied to aquatic vegetation, particularly cattails and sedges in marshes and shallow water bodies.
- Lifecycle: Their lifecycle has a unique larval stage. Unlike most mosquito larvae that breathe at the water’s surface, Coquillettidia perturbans larvae attach themselves to the roots of aquatic plants using a specialized siphon. They remain attached throughout their larval and pupal stages, making them less susceptible to typical surface-based control methods. They emerge in large numbers, often after a period of undisturbed development.
- Special Concerns: Their painful bites can be a significant nuisance, making outdoor activities unpleasant near infested areas. While they can transmit some diseases, they are not considered a primary vector of major concern in Essex County.
2. Common House Mosquito (*Culex pipiens*)
- Description: These are small, brown mosquitoes known for their high-pitched whine and nocturnal biting habits.
- Where They’re Found: They are highly adapted to urban and suburban environments, breeding in stagnant water sources commonly found around homes. This includes bird baths, rain barrels, clogged gutters, and any other container that can hold water.
- Lifecycle: Their lifecycle follows the typical four stages, with eggs laid in rafts on the water’s surface. The speed of their development depends on water temperature, but it’s generally quite rapid in warm summer months.
- Special Concerns: Culex pipiens is a significant vector of West Nile virus in our region. They feed on infected birds and can then transmit the virus to humans. Eliminating breeding sites around your home is a key preventative measure. For more tips, see our article on DIY mosquito prevention in your yard.
3. Eastern Tree Hole Mosquito (*Ochlerotatus trivittatus*)
- Description: This medium-sized mosquito is dark with distinct silvery-white markings on its thorax and legs. They are known for their aggressive daytime biting.
- Where They’re Found: While their name suggests tree holes, they also readily breed in other natural and artificial containers that hold water, such as buckets, tires, and even plant saucers, particularly in shaded areas.
- Lifecycle: Their eggs are typically laid on the sides of containers just above the waterline. These eggs can survive dry periods and hatch when the container fills with water. This allows them to persist even if temporary water sources dry up.
- Special Concerns: Ochlerotatus trivittatus is an aggressive biter, making outdoor activities unpleasant during the day. They are also a potential vector for diseases like West Nile virus.
4. Inland Floodwater Mosquito (*Aedes vexans*)
- Description: This is often the most abundant and nuisance-biting mosquito in Essex County. They are medium-sized, brownish, with pale bands on their abdomen and legs. They are known for their persistent and aggressive biting, especially after rainfall or during humid evenings.
- Where They’re Found: As their name implies, they breed in temporary pools of water created by rain or flooding in fields, ditches, woodlands, and even low-lying areas in your yard. Their eggs are laid in damp soil and can survive long periods of dryness, hatching en masse when flooded. This can lead to large, sudden increases in their population.
- Lifecycle: Their lifecycle follows the standard four stages, but the drought-resistant eggs are a key adaptation that allows for rapid population booms. They are strong fliers and can travel considerable distances from their breeding sites.

- Special Concerns: Aedes vexans is a significant nuisance due to its aggressive biting behavior. They are also capable of transmitting West Nile virus.
5. White-dotted Mosquito (*Culex restuans*)
- Description: This species is very closely related in appearance and behavior to the Common House Mosquito (Culex pipiens). They are small and brownish.
- Where They’s Found: They share similar breeding habitats with Culex pipiens, utilizing stagnant water sources around homes, including rain barrels, bird baths, and other containers.
- Lifecycle: Their lifecycle is virtually identical to that of Culex pipiens, with eggs laid in rafts on the water surface.
- Special Concerns: Like Culex pipiens, Culex restuans is a known vector of West Nile virus. Due to their similar habits and appearance, both species contribute to the risk of transmission in our area.
6. Woodland Pool Mosquito (*Ochlerotatus stimulans*)
- Description: These are medium-sized mosquitoes with distinctive white or pale markings on their dark legs and abdomen, giving them a somewhat striped appearance. They are aggressive biters, particularly in wooded or shaded areas.
- Where They’re Found: They primarily breed in temporary pools of water in wooded areas that form in the spring from melting snow and rain.
- Lifecycle: They have a single generation per year. The adults emerge in the spring and early summer and can be quite bothersome during this time. Their eggs are laid near the edges of these pools and overwinter, hatching the following spring.
- Special Concerns: While their aggressive biting can make spending time in wooded areas unpleasant, they are not considered a primary vector for major diseases in Essex County.
