What are Tiny Black Flies?

Tiny black flies, also known as biting midges or no-see-ums, are small flying insects that are common in the UK. They are typically around 1-3 millimeters in length and have a black or dark-colored body. Despite their small size, they can pack a painful punch with their bites.

These flies are attracted to moisture and warmth, which is why they are often found near water sources, such as lakes, rivers, and coastal areas. They are also drawn to dark colors and sweet-smelling perfumes, which is why they may be more attracted to certain clothing or personal items.

While their bites can be uncomfortable, they are generally not serious and will heal on their own within a few days. However, in some cases, they can cause an allergic reaction or transmit diseases such as leishmaniasis or chikungunya.

In the UK, tiny black flies are most active during the summer months, typically from June to September. During this time, they can be found in large numbers in certain areas, particularly in the north and west of England.

It's worth noting that while tiny black flies are the most common type of biting fly in the UK, there are other types of biting flies that can also be found in the country, such as horseflies and deerflies.
