The common green bottle fly is distinguished by its metallic bluish-green or goldish coloring. These flies are slightly larger than the common house fly and are normally 10-14mm long. Bottle flies prefer warm and moist climates and prefer to feed and reproduce on meat, fish, animal corpses, open wounds, or excrement.
The cluster fly is a type of blowfly that can often be a household nuisance, especially in late summer or fall when they enter houses to hibernate. These flies do not lay eggs in human food, and they are solely parasitic on earthworms. The cluster fly is about 7mm long and is distinguished by lines or stripes behind the head and short golden hairs on the thorax.
The crane fly is a slender, long-legged fly that can vary in length from 2-60 mm. These flies are weak fliers and can be easily caught. Females carry their eggs on their abdomen, so they may appear larger than the males. Females also have a pointed abdomen that appears to be a stinger, but is actually harmless. They flies do not bit humans
The fungus gnat is a small, dark fly that is about 2-5 mm long when mature. Fungus gnat larvae feed on plant roots or fungi, and adults are crucial to the process of spreading mushroom spores and plant pollen. These gnats are often attracted into homes when plants are overwatered. They often don’t cause much harm to health plants, but can severely damage seedlings.
The house fly is the most common of all domestic flies and accounts for about 90% of flies inside human habitations. These flies are distributed throughout the world and can carry a variety of pathogens, such as typhoid, cholera, and salmonella. House flies are 8-12 mm long and have a gray thorax with four dark lines on their back. The female house fly will lay about 500 eggs in a lifetime. These eggs will hatch within a day and feed on organic material, such as garbage and feces.
The phorid fly is a species of hump-backed flies that prefer running over flying. They are about 1/4in long and range in color from black or brown to yellow. These flies are found worldwide, but they are commonly found in tropical areas. Several species of the phorid fly have been introduced in the US to help control the fire ant population since phorid flies reproduce by laying eggs in the thorax of the ant.
