Where does the fly take place

Encounters with nature 2, textbook

Insect fly larvae are legless and eyeless. After mating they lay their eggs. A housefly clutch consists of around 150 eggs. Preferred egg-laying sites are, if possible, food, but also excrement, rotting plant material, compost and carrion - substances that serve as food for the larvae. The legless and eyeless larvae (maggots,  Fig. 52) hatch from the eggs after 12 to 24 hours. They start to feed immediately and grow up quickly. They molt twice in total before pupating after five to six days. This hardens the outer skin of the maize. The brown, oval dolls look like small barrels. They are therefore also referred to as barrel dolls ( Fig. 49). With the help of the forehead bladder, the fly hatches out of the doll's shell. After about a week, the adult, sexually mature fly hatches. With the help of a forehead blister that inflates, she ruptures the lid of the doll's shell. Houseflies lay up to 1,000 eggs in the course of their life. The housefly mates for the first time as early as three days. She is two to four weeks old. During this time, the female flies lay up to 1000 eggs. Meat flies lay up to 20,000 eggs in the course of their life. The meat flies, which are around 15 millimeters in size, inhabit similar habitats as house flies. However, they mainly feed on nectar, plant juices and windfalls. The females like to lay eggs on carrion, feces, foods such as meat and cheese, but also in wounds of living animals. The maggots usually hatch immediately after they lay eggs and start eating. Sometimes the eggs are also laid on earthworm droppings at the entrance to rainworm tunnels. After hatching, the larvae look for the earthworm, penetrate it and eat its interior. The worm dies. Pupation takes place after about a week. The finished insects hatch after eight to ten days. Meat flies live one to two years. During this time they lay up to 20,000 eggs. 49 Barrel dolls 50 Meat flies 51 Mating meat flies 52 Fly maggots Fly or not a fly, that is the question! Although some insects are called "flies", strictly speaking they do not belong to the order of the flies, but form their own orders. Below are three insects, their names and their respective larvae. Look up an insect identification book and match correctly by connecting. Mark with a cross by the name which of the three "flies" is the only one that belongs to the real flies. It's your turn!
