Before you head outside, be sure to read up on these tips for dealing with these tiny pests. Black fly season typically starts in the middle of May and runs through late June or early July.
The flies are most active several hours after sunrise and an hour or two before sunset due to the humidity of the air and the position of the sun. When the air is dry, flies may seek moisture in leaf litter on the ground. Although their bites do not spread disease to humans, they are painful, itchy, and can even cause severe allergic reactions in some people.
Instead, they prey on other animals, such as other mammals or birds. And on top of that, only female black flies bite.
To the everyday person, black flies of different species look identical, Kirby said. The female black fly feeds on blood for the nutrients it needs to lay hundreds of eggs. In addition, both male and female blackflies feed on flower nectar. And black fly larvae filter organic matter and small invertebrates out of the flowing water they hatch in.
This species was notable because it did — and continues to — swarm and bite people late in the season, when other black fly species tend to drop off. This species, given the scientific name of Simulium penobscotensis, is especially active in July and August.
Black flies lay eggs in moving water, such as brooks, streams and rivers. And upon hatching, black flies spend two stages of life — as larvae and pupae — in the water, filtering food from the current. Therefore, clean waterways with a high level of dissolved oxygen are especially important to black fly production. But the reason was the waters of Maine were so polluted at that time.
Plus a lot of animals and other insects feed on the larvae and the airborn adult. People have long been studying what attracts black flies. Over the years, studies have supported the ideas that black flies are attracted to certain colors , scents and carbon dioxide , which is expelled when a person breathes.
