Biting midges are tiny flies that can cause itchy, red, and irritating bites on humans and animals. Many people call them no-see-ums because they are so small that they are hard to notice before they bite. These insects often live near damp soil, marshes, beaches, wetlands, farms, gardens, and shaded outdoor areas. In this guide, you will learn about 17 common types of biting midges, how to identify them, where they live, how they behave, and what makes their bites so annoying.
1. No-see-um
The No-see-um is one of the most common names for tiny biting midges. These insects are so small that people often feel the bite before they notice the insect. No-see-ums are usually active around damp areas, beaches, marshes, lakes, gardens, and shaded outdoor spaces, especially during warm and humid weather.
Identification
- Very tiny biting fly
- Often smaller than a mosquito
- Gray, brown, or dark-colored body
- Short wings with a delicate appearance
- Small enough to pass through many window screens
- Often seen in groups near damp areas
- Bites may feel sharp or burning
- Bite marks may become red, itchy, or swollen
Habitat and Distribution
No-see-ums are commonly found in warm, moist environments where they can breed and feed. They often live near marshes, wetlands, beaches, lakes, rivers, ponds, and damp soil. They may also appear in gardens, wooded areas, and coastal neighborhoods. Their distribution is wide, especially in regions with humidity, standing water, and organic matter.
Behavior and Diet
Adult female No-see-ums bite because they need blood to help produce eggs. They often feed on humans, pets, livestock, birds, and wildlife. Males usually feed on nectar or plant fluids. No-see-ums are most active during calm, warm periods, especially around dawn, dusk, or shaded daytime areas where wind is low.
Life Cycle
The life cycle of No-see-ums begins when females lay eggs in moist soil, mud, sand, or decaying organic matter. The larvae develop in damp places and feed on tiny organic particles. After the larval and pupal stages, adults emerge and begin feeding, mating, and reproducing. Warm, wet conditions can help populations increase quickly.
2. Punkie
The Punkie is another common name for a tiny biting midge, especially in some regions where these insects are common around wetlands, woods, and damp outdoor areas. Like no-see-ums, punkies are very small but can cause irritating bites. They are most noticeable during warm, humid weather when people spend time outside near moist habitats.
