Characteristics: Brown body, long and fragile-looking legs

The common house mosquito is likely what many of us think of when we hear the word mosquito. It has a small brown body and fragile-looking legs. You might also notice white bands across the abdomen. The females drink blood from humans, birds, and other animals, while the males primarily eat nectar and other sugary substances.

2. White-Dotted Mosquito

Characteristics: Dark body with white spots

The white-dotted or polka-dotted mosquito is not as common as the common house mosquito, but you can find them throughout Pennsylvania. It’s a dangerous species that bites during the day, unlike most other mosquitos. It also spreads yellow fever, dengue fever, chikungunya, and other diseases. They are small but easy to identify by their black body with white spots or stripes.

3. Inland Floodwater Mosquito

The inland floodwater mosquito is a variety that you will often encounter around water. The females prefer human and cattle blood, while the males eat nectar, sap, and honeydew. These mosquitos are responsible for transmitting heartworm to pets, and they can carry a deadly rabbit disease. It has small wings and long legs.

4. Rock Pool Mosquito

Characteristics: Lyre-shaped pattern on the scutum

The rock pool mosquito is a day-biter that enjoys dense forests. It’s reluctant to feed on humans, reptiles, and amphibians and gets most of its blood meals from birds and mice. These insects overwinter as eggs in cool environments, like Pennsylvania, and arrive in early spring.

5. Eastern Tree Hole Mosquito

Characteristics: Lays its eggs in trees or old tires

The tree-hole mosquito is easy to find in the woodlands of Pennsylvania. As the name suggests, these mosquitos like to lay their eggs in water that they find in tree holes but will also use water that they find in old tires. They usually get their blood from rodents but will feed on a human if available, and they can transmit several diseases.

6. Yellow Fever Mosquito

Characteristics: Large in size

Yellow fever mosquitos are rare in Pennsylvania, but they are an invasive species, so scientists expect their population to grow over the next several years. They feed during the day and can transmit several diseases, including yellow fever. They breed in standing water and like to live in small containers, like flower pots or even a drainage ditch. They’re hardy and difficult to control once a population gets started.

7. Asian Tiger Mosquito

These small, fragile insects live all across the state and enjoy biting humans just before the sun goes down and right before it comes up. The inland floodwater mosquito is another common variety that you can find around water, and it spreads several diseases. The Asian Tiger mosquito is likely the most terrifying because it can bite dozens of times per minute.
