| Their larvae are up to 120 mm in length. The larvae prefer to live in and feed on rotting wood and develop in oak forests or in places where other plant material rots. During their development (3 to 5 years) they profit from the warmth created by the decomposition of the plant material. The mature larvae pupate in a cavity approximately ... | | |

| The females lay 100 to 150 eggs in garbage, compost, food or excrement. The larvae (maggots) hatch within a day and immediately start feeding on the rotting substrates surrounding them. The larvae have no legs and there is no clear separation between their heads and bodies. The maggots later pupate and remain as pupae for about 3-8 days before hatching as adult flies. 3 days after hatching they reach... | | |

| The twin-spot centurion soldierfly is active from August to October. The females lay their eggs in bark or rotting foliage and the larvae develop there. | | |

| Soldier flies | | ...spikes on the end of their chests.
Soldier flies prefer forest areas. They suck on flowers, eat pollen or live off organic substances from animals. Some species live near water in which their larvae develop.
The females lay their eggs on rotting plants, aquatic plants, or on the water’ssurface.

| While the adults of some dung fly species prey on small insects or larvae, other types live off feces. The larvae eat parts of plants (leaves, cambium, boll) and rotting plants , or live off feces like the adults. | | |

| The larvae of Helophilus pendulus are called rat-tailed maggots and live in muddy waters (including slurry pits) where they feed on rotting organic substrates. They breathe through a long ‘snorkel’ attached to the end of their abdomen which runs to the surface of the water. | | |
|
| ...The males have a distinctive, hairy brace apparatus on their abdomens.
Long-legged flies prefer to be in proximity to water. While some species prey on insects and worms, others feed on nectar and honeydew.
The females lay their eggs on rotting plants, under bark or in reeds. Some species lay their eggs in water. The larvae feed on plant substrates first, and later on small insects, often unselectively. The pupae have breathing tubes and are hidden in cocoons. | | |

Females lay eggs individually on rotting plants. In this humid environment, the larvae develop. Their bodies are uniform in shape, flattened and tapered at the end. They have leathery skin, which is strengthened like a shield in the course of their development in limestone deposits. Thi... | | |

| The females lay their eggs on rotting plants, under bark or in reeds, using a special ovipositor which enables them to bore holes. After hatching, the larvae feed initially on the surrounding plant substrates. In a later stage of their development they prey on small insects, just as ... | | |

| ...heaps where they await females for mating. The mating takes place at another location later on.
The female flies lay their eggs on dung-heaps or compost heaps. From the first or second day after hatching, the larvae begin feeding on feces or rotting parts of plants. At the end of their third larval stage the fully developed larvae turn into pupae. This happens in the dung or compost or in the soil below it. From egg to adult fly can take 14 to 32 days.
