Yellow flies are a type of fly that is common to Florida. The fly‘s official name is the Diachlorus ferrugatus (Fabricius), and it has a yellowish body that has given rise to its nickname. The fly is known for its fierce bites as well as of course its unusual yellow color.
These flies are a small insect, measuring about 3/8 inch in length. They have one pair of black legs and two pairs of yellow legs. Their wings are clear with patches of yellow, black and brown. The eyes of this fly are often what people notice the most – the eyes are a bright green with purple bands. These flies lay white eggs that measure a tiny 1/16 inch long.
The larvae of these flies eat decaying materials and molt many times before they become adults. The females lay their eggs on items such as plants and sticks that are over water. It takes up to 12 days for the eggs to hatch, and the new larvae drop down into the body of water in order to eat organic material in the water. From the time the egg is laid to the time that the adult emerges from the water is about one year.
One reason that so many people dislike the yellow fly is that the females bite humans. They are aggressive and leave painful bites behind that can swell and itch. The most active time for biting is the late afternoon, and they bite more on cloudy days. However, they can bite at any time of day. They drink the blood of the humans they bite, and often several yellow flies will attack at once.
Anytime a human is near a body of water, particularly one that is near a forest, they may be vulnerable to yellow fly attacks. Because the fly doesn’t make a buzzing sound, it can be difficult to know that a yellow fly is attacking until the painful bite occurs. And, it isn’t just humans that are vulnerable to the bites. Pets such as dogs are also bitten by these flies, but these flies generally don’t bite cattle often. In Florida, yellow flies are in the air from March through November.
