Mosquitoes are small, flying insects belonging to the family Culicidae. They are found in various habitats worldwide, except for extremely cold environments. There are thousands of mosquito species, but only a few hundred of them are known to bite humans. Female mosquitoes are the ones that bite, as they require blood for egg development.
It’s important to protect yourself from mosquito bites, especially in areas where mosquito-borne diseases are prevalent. This can be done by using mosquito repellents, wearing protective clothing, and staying indoors during peak mosquito activity times, such as dusk and dawn.
Asian Tiger Mosquito
Adults of this mosquito have black bodies with conspicuous white stripes. A distinctive single white stripe runs the length of the back. Body length is approximately 0.5 centimeters. Distinct silver-white bands are evident on the palpus and tarsi. Eggs are approximately 0.1 centimeters in length and dark brown to black. Eggs are laid in moist areas just above the water surface and are capable of overwintering. Eggs hatch upon inundation and immature stages (larvae and pupae) of the life cycle occur in water.
These mosquitoes thrive in urban and suburban areas, as well as in rural environments. They are known to breed in a variety of artificial and natural water sources, such as flower pots, discarded tires, tree holes, and puddles. Larvae are filter feeders and occur in standing water found in discarded tires, small containers, and tree holes. Pupae are comma-shaped and dark brown in color.

Southern House Mosquito
Adult Culex quinquefasciatus vary from 3.96 to 4.25 mm in length (Lima et al. 2003). The mosquito is brown with the proboscis, thorax, wings, and tarsi darker than the rest of the body. The head is light brown with the lightest portion in the center.
The antennae and the proboscis are about the same length, but in some cases, the antennae are slightly shorter than the proboscis. The flagellum has thirteen segments that have few to no scales (Sirivanakarn et al. 1987). The scales of the thorax are narrow and curved. The abdomen has pale, narrow, rounded bands on the basal side of each tergite. The bands barely touch the basolateral spots taking on a half-moon shape (Darsie and Ward 2005).
Like many other mosquito species, the southern house mosquito can transmit diseases to humans. It is a known vector for diseases such as West Nile virus, St. Louis encephalitis, and lymphatic filariasis. The transmission of these diseases occurs when the mosquito bites an infected individual and subsequently bites a healthy person, thereby transferring the pathogens.

Tree Hole Mosquito
Aedes triseriatus (Ochlerotatus triseriatus) are found in the eastern half of the US and southern Canada. Ae. triseriatus normally lays its eggs in pools of water accumulated in tree holes, but it will also lay eggs in man-made water-holding containers, particularly discarded tires. They reproduce most frequently in natural or suburban forested areas. Ae. triseriatus overwinter as eggs located in dry nesting sites that become flooded in spring. Adults typically live two to five weeks.
They are generally found in woodland/forested environments, including in suburban areas, and are infrequent in open areas. Ae. triseriatus normally lays its eggs in pools of water accumulated in tree holes, but it will also lay eggs in man-made water holding containers, particularly discarded tires.
The breeding cycle (egg, larvae, pupae, adult) occurs over multiple seasons as Ae. triseriatus overwinter as eggs located in dry nesting sites that become flooded in spring. They have dark, unbanded legs, a black band in the middle of the thorax surrounded by silver/white on the side, black proboscis, and a black abdomen with silver scales laterally. Primarily mammalophilic, Ae. triseriatus most often feed on rodents but will also take a blood meal from humans. Feeding activity is largely crepuscular. Ae. triseriatus are the primary vector of La Crosse virus throughout their range but also transmit numerous other viral ailments.
