1 FLIES

2 WHAT ARE FLIES? True flies are insects of the order Diptera,possessing a single pair of wings on the mesothorax and a pair of halteres, derived from the hind wings, on the metathorax. There are more than 100,000 different species of flies. Like all insects, flies have 6 legs and segmented bodies consisting of a head, a thorax and an abdomen. Flies have hairy, sticky feet and are able to walk upside down. Their special feet enable them to land on smooth surfaces (like your wall) and not slide off. Flies cannot chew. They have to suck up their food. Flies have mouth parts that absorb food like a sponge. At your next family picnic when flies are buzzing around your aunt's potato salad, casually mention that scientists have estimated that houseflies carry around 1,941,000 different kinds of bacteria.insectsorderwings mesothoraxhalteresmetathorax

3 Some of the diseases Some of the diseases Leishmaniasis This disease is found in South America, Africa, Indian Subcontinent and Europe. Leishmaniasis This disease is found in South America, Africa, Indian Subcontinent and Europe. It's caused by a parasitic protozoan transmitted by the bite of sand flies.

Flies rummaging around excrement may come across bacteria known as Salmonella Typhi, which may come from a person shedding it. This disease is a type of fever. Symptoms include a body temperature of as high as 103 to 104 F (39 to 40 C), weakeness, stomach pains, headaches, and/or loss of appetite. This disease is a type of fever.

4 WHAT DO THEY EAT? Larvae feed on decaying meat and feces. Adult flies feed on sugary food any kind, including nectar and rotting fruit. Their food has to be in a liquid form in order for them to eat it. Different flies dine on different foods. Flies around the world eat nectar, plant sap, blood, other insects, and decaying matter. Did you know that a mosquito is actually a type of fly? Of the species of flies that eat blood, only the females are the blood eaters. They need the nutrients in blood to be able to lay eggs. The males of these species usually dine on nectar from plants and flowers. The species of flies that we call houseflies like to eat OUR food! Larvae feed on decaying meat and feces.

5 WHERE DO THEY LIVE? They buzz about when the day is nice and warm, and the garbage (one of their main sources of food) is especially stinky. They spend their time at the usual seedy spots -- on the bodies of dead animals, around piles of feces, or with some nice, decaying vegetation. Unlike many insects, flies don't have much need for permanent abodes. Perhaps it's because the little buggers have such short life spans. On average, the lives of flies can be measured in weeks, so maybe they prefer to spend their precious time scavenging for food and living for the moment.

6 OH MY ! Flies lay eggs on their food. This also could possibly be your food too. Flies lay eggs on their food. This also could possibly be your food too. Flies have a glue like substance on the pads of their feet that help them stick to surfaces. Flies vomit on food before eating it. They can only consume liquids so their vomit is a tool to liquefy their food. Their saliva turns the rest into complete liquid before they swallow it.
