Dealing with flies swarming around your house can be a big challenge if you don’t know what kind of flies you are dealing with.

If you have spotted flies having clear wings with black-brown or yellow patterns, then you have most probably encountered a picture-winged fly. 

These are very common across North America. In this article, we will discuss more how to get rid of them. 

What are Picture Winged Flies?

The Picture-winged flies are known for the bold patterns in their spotted wings. They have an ant-shaped body and can grow from 0.25-0.5 inches in length. 

These flies are somewhat similar to fruit flies, flutter flies, signal flies, lance flies, and more.

You can recognize the adult flies by the shiny black-brown wings with slight touches of yellow. These wings can grow up to 0.23 inches in length. 

The body is mostly light brown in color with brown to yellowish-brown legs. 

Are They Pests?

A picture-winged fly is harmless to humans and pets as they do not bite and cause any damage to your home and the furniture in it. 

However, these insects are significant pests of sweet corn in Florida

Apart from that, they do not cause much of a problem to humans, but the sight of a bunch of these flies gathering around your house can be a little too much to bear.

This is why people might want to take active measures to get rid of them. 

However, you must know that these flies play a significant role in keeping the surroundings clean by getting rid of decomposing organic matter effectively.

What Do They Eat?

The larvae of these flies usually consume decaying matter; you can find them swarming around piles of rotting organic material like plant matter, vegetables, and fruits. 

Nectar and flowing sap are the main food sources for adult picture-winged flies. Hence you can spot them near flowering gardens.

The larvae also actively consume sweet corn (as mentioned earlier). 

Due to their feeding habits, you can spot these flies swarming around moist areas like bottomlands where things usually rot. 

What Eats Them? 

There are many active predators of the picture-winged flies, including different kinds of birds like phoebes, wrens, flycatchers, tanagers, and more. 

Apart from birds, these flies are also hunted down by giant spiders and other predatory insects as well.

When Do They Come Into Homes?

The flies usually live around moist places that promise plenty of decaying matter for them to feed on, but they can also creep into your homes. 

Dealing with a bunch of flies buzzing around inside your house is not a pretty sight which is why you need to be a little cautious.  

These flies usually enter the homes during the winter season to survive the cold but ironically, adult flies never survive the winter. 

In the next section, we will take a look at a few practical ways to keep these insects away from your home.

How To Get Rid of Them?

Since flies love to be around decaying matter, you should always keep your house clean by regularly taking out the trash. 

Make sure that you keep the moist area in check, like sink drains, drain pipes, and more.

If the flies have already entered your home, there is no need to use insecticide, as they will eventually die once the surroundings get a little colder. 

The flies can also enter through tiny cracks and gaps in your windows, door, or walls. 

Therefore a thorough check for these cracks and gaps; if you find some, make sure that you immediately seal them up. 

If you continue to have issues call a local pest control company. Hiring a trained professional will help get rid of those pesky flys.

Frequently Asked Questions 

Where do picture-winged flies live?

Pictured-winged flies usually live in moist areas that are ideal for rotting organic material to exist. 
The adult flies also actively consume flower nectar and sap flows, so you can spot them around the flowering garden as well. 
During the winter, they can creep into the house to survive the cold.

How do you get rid of Ceroxys Latiusculus flies?

To get rid of these flies, you must make sure that all the cracks and gaps in your house, as the flies can use them as entry points to your house. 
They usually enter homes to survive the cold during winter. If you find a few of these flies inside your house, there is no need to use insecticides on them, as they will probably die when the temperature gets a little colder.

How do you get rid of buzzy flies?

These flies are attracted to moist places that have decaying organic matter, like fruits, vegetables, and more. Therefore you must routinely take the trash out of your house. 
If a lot of trash gets accumulated at a place, the flies will definitely get attracted to that. You also must clean other moist surfaces in your house, like sink drains, drain pipes, and more, to keep the flies away. 

How does vinegar get rid of flies?

Vinegar is a great source to create a trap for flies. Here you fill a big bowl with vinegar and mix it with a small amount of dish-washing soap. The sweet smell of the vinegar will attract flies to investigate the mixture. 
Once they fall into the liquid, the dish soap will decrease the surface tension of the mixture, due to which the files will immediately drown without being able to escape.

Wrap Up

The picture-winged flies might be good to look at but the sight of them swarming around your house is not a pretty one. 

Moreover, in places like Florida, where their larvae are notorious for eating sweet corn crops, effective measures are necessary to keep them in control.

You can use the tips and tricks mentioned in this article to handle these flies.

Subject:  Ant/Wasp like creature found on window
Geographic location of the bug:  Montreal, City Area
Date: 06/30/2018
Time: 04:55 PM EDT
Your letter to the bugman:  It was around as big as the tip of my index finger (not including the wings). This wasp/ant like creature was all brown except for its abdomen, which was a darker shade of brown. It had a retractable stinger, I saw it and has black and white wings. I saw it on the opposite side of my window facing outside my house. I saw it on a cloudy hot summer day around dusk time, around the end of June. I am curious to know what kind of species it is, and if it is dangerous or not. I cannot find anything about it on the Internet, maybe it is a new species? Thank you!

Red, deer-headed fly – non-archived! Intriguing!
Hello again!  I hope you take a look at this email, as I’ve never seen anything like this fly in my life.  I checked through a great deal of your extensive archives, and even the Hanging Thief, with its similar coloration, was not a match.
I haven’t seen another one since I saw this one.  It was beautiful, but kind of creeped me out because of its very strange way of moving – it moved in little jerks, and continually rotated its wings and halteres in this slow fanning motion while standing (maybe this is normal but I’ve never seen it).  I’ve attached an admittedly short and low-quality video to illustrate these motions – if you have enough inbox space and would like to see better video, I’d be glad to share my nicer files with you.
In case it helps in the identification, there were lots of full trash cans and some animal excrement nearby.  Vegetation around the place I saw it is primarily pines, oaks, sweetgums, maples, etc., and cultivated plants as well: ornamental grasses, magnolias, mulch, and redbuds, among others.
Until I figure out what it is, I’ve been calling it the Fawn Fly because its head shape and markings remind me of a deer fawn.  I’d love to know what it really is! Thanks,
R. Thompson

Hi Pat,
This unusual creature is a Picture Winged Fly in the family Ulidiidae. Of all the species posted to BugGuide, your photo looks most like Delphinia picta, but both the head shape and wing pattern are different. We will contact Eric Eaton to see if he can provide a species identification.

Daniel:
Sorry to be late in replying….
The picture-winged fly is Tritoxa incurva.  Looks like it has its mouthparts extended, giving it a long-faced look.

Mystery Fly
August 26, 2009
Hi, I’ve noticed some mysterious flies around my yard, and I’ve been unable to identify them. They don’t seem interested in the normal waste and rot that many regular flies like, and seem to be solitary. They have ferocious looking piercing mouthparts, and their overall shape reminds me of a military helicopter. Maybe that’s just me, though. I’ve been trying for weeks to get a picture, and they’ve eluded me — until this morning, when I found a dead one tangled in an old spider web. It’s slightly dessicated, but I believe there’s enough detail for an ID. I hope.

I’ve had a bunch of these flies in my yard for the past couple of years. I’ve tried to find out what kind of fly this is on my own with out any luck. In fact, trying to I.D. this fly on my own is part of what led me to your site.
Sadly, my camera gave me a hard time with focusing on this fly, so I was only able to get this one picture before it became annoyed with me and flew off. I was hoping that you’d be able to help me I.D. it.

Thank you for any help!

Letter 10 – Picture Winged Fly: Idana marginata

 

Subject: New Jersey Fly, help with ID request
Location: North Eastern New Jersey
June 14, 2014 3:43 pm
Hello again, was wondering if when you have time, you could help me ID a fly from New Jersey. I was breaking out my macro lens to try and get some shots today. Came across this fly that I can not identify. My thoughts are either the picture wing family or the fruit fly family. (could be light years off). What was puzzling me was the way she was sticking her ovipositor into the tree bark, her almost wasp or bee like colors and the patterns on her wings. Definitely a fly, could see the halteres, mouth parts and antenna quite clearly. Medium size. Sorry I only have close ups of her face and some blurry shots of her digging into the tree bark. (Macro stinks on moving targets.)
Would love to hear your answer but understand you are VERY busy. So if you get to them great, if not you still have my thanks for the wonderful site.

  1. Thanks for your help.

    “Breeds is decaying organic matter” isn’t a suprise to me. I’m a homebrewer, meaning I brew beer as a hobby, and keep a pile of spent grain next to my shed. These little guys started showing up right around the time I made the switch to all-grain brewing and started building up the grain pile.
