What is a filth fly (diptera) and what kind of habitat does it prefer?

Filth flies is a generic name for various species of flies that live on decomposing material. The kinds of flies that make up filth flies are subject to interpretation; I decided to go for a broader definition of the term, that includes medium size species like the house fly to large species such as soldier flies.
Like their more distant relatives, the mosquitoes, filth flies may live around people and cause harm.  Filth fly is a generic term for various species of fly, large or medium-sized. Their larvae look like worms and are called maggots. The most common is the house fly, (Musca domestica), gray with a lined thorax and red eyes. Blow flies and bottle flies are larger, with metallic blue and green colors. Their larvae usually live on dead animal tissue, such as carrion, roadkill, near  plants which process meat products. Adults prefer sugary food sources, but they still come in touch with dead animals where they lay their eggs. Soldier flies are large flies with black wings and “elbowed” antennae. Their larvae, or maggots, and pupae are over one inch long, dark brown and flattened. Flesh flies look a bit like the house flies, with stripes on their thorax, but they are larger and may have a checkerboard pattern on their abdomen. In some species the tip of the abdomen is red. Flesh flies usually lay their eggs on dead animals or dog waste, but their name comes from their habit of laying their larvae in open wounds. The female does not lay eggs, but keeps them inside the body. When it finds a suitable food source, it deposits the maggots, which soon burrow under the surface of the carcass or other feeding material.

Filth flies are to be found worldwide. They are to be found anywhere they may find their favorite food sources, which are all sorts of decaying and decomposing matter: plant or animal waste (such as manure), garbage, carrion, sludge, all organic debris or rotting material. They are more present in rural areas than in urban areas, especially near farms, slaughterhouses and meat-processing units. Adult flies do not consume solid food, but instead lick all sorts of liquids, spreading their saliva and vomit wherever they may go. Also, they eat relatively much and defecate a lot.  They may carry diseases to human food sources and preparation areas and contaminate them.  Food sources for them and their larvae may be infested with pathogens. Filth flies are known to carry germs for over one hundred diseases, such as hepatitis, polio, dysentery, typhoid, cholera, anthrax, tuberculosis and others. Among the germs they carry are Salmonella, E. coli, Giardia, and  eggs of parasitic worms such as the roundworm Ascaris, whipworm, hookworm, dwarf tapeworm and pinworm.

In order to get rid of filth flies one must, first of all, eliminate their food sources from the environment (such as pet feces) or access to trash or dead animals. Secondly, access to human habitation must be restricted. Still, flies may travel miles and still are able to get inside buildings alongside humans or through cracks and holes.  Therefore, we may need pest control measures.

Should you be concerned about stoneflies (taeniopterygidae)?

Stoneflies (taeniopterygidae) as known as willow flies are relatives of the grasshopper and termite. Adult stoneflies are dark brown or black and can be found during the day or at night. Stoneflies can range anywhere from 5-50mm in body length. They tend to spend most of their lives as larvae, living at the bottom of rivers/streams, hanging onto rocks and other wooden debris.  Stoneflies are typically found in the winter season, while most other insects are hibernating. They primarily live near high paced streams, rivers, bridges and stones. Many other

pollutants in the air during the fall and spring, causes a reduction in oxygen levels for the stoneflies. So, winter becomes the most active time for stoneflies. Should you be concerned of stoneflies? None to say the least. Seeing Stoneflies in your local rivers/streams is a positive sign of a healthy environment as they thrive on the water quality within those waters. Streams and/or rivers with low oxygen levels and any signs of pollution do not support the growth and proper living conditions to stoneflies. Which is why Pollution Control Agencies love them…because they are so sensitive to water conditions, it helps the agencies get an idea of the river’s water quality within that area. Stoneflies need high amounts of dissolved oxygen from the rivers so, when the dissolved oxygen levels are low the stoneflies disappear. A rule of thumb is that typically if trout live in the water, it is more than likely that so are the stoneflies as they both tend to need the same environmental qualities.

Stoneflies are not like your typical house fly. They will not bother you when you are out on your family day picnic or surrounding your fish basket when you are out of the boat. Stoneflies are like dragonflies. You may see them and they may fly close, but never to eat anything on you or in your basket. Stoneflies are actually detritivores. Detritivores tend to eat broken down organic matter such as living or dead plant material. As juveniles, stoneflies feed of organic plant material or aquatic vegetation. However, as adults, stoneflies tend to stop eating vegan and have been known to eat aquatic insects as well as other stoneflies.The best time to catch some of these amazing stoneflies within your area, are during the winter time down by the streams when the streams are covered in snow.
