Biting midges are tiny black flies that bite humans when they’re outdoors. 

Also known as no-see-ums, or punkies in Florida, these biting flies are 1-3 mm in size.

They’ve got a pair of wings with dark patterns that cover their entire bodies when they’re at rest.

Biting midges don’t have a beak or proboscis like mosquitoes to draw blood from their hosts.

They’ve sharp blade-like mouthparts that they use to rip open the skin to draw blood.

Sever itching, red rashes, and burning sensation on the skin ensue after the bite.

No-see-ums bites occur mostly at the outdoors near the water bodies such as lakes, streams, ponds, marshes, and swamps.

Dawn and dusk are the typical periods when biting midges are active.

And they attack humans and animals to feed on their blood.

So, they wonder what’s biting them that they can’t see. 

Point to note here is that it’s only the female biting midges that bite humans and animals to draw blood. 

The reason is that females need blood to process and develop eggs in their bodies. 

The male midges don’t bite. They feed on the flower nectar. 

Biting midges are active in the entire summer.

As the temperature starts to drop with the beginning of fall, their numbers start to decrease.

The best way to protect yourself from biting midges’ bites is to wear DEET-based insect repellent and have minimum exposed skin.

Sand flies have hairy wings that are slanted upwards at a 45 degree angle while at rest.

Buffalo gnats will lay their eggs in submerged objects like stones submerged inside the water.

Black flies are terrible biters. And they also draw blood from animals and humans. 

Their sharp scissor-like mouthparts cause laceration on the skin to draw blood.

The bites are intensely itchy and the symptoms include swelling and rashes.

In some cases, bleeding from the bitten wound can also occur.

Another thing is that minute pirate bugs don’t take off after biting you.
