They develop from egg to adult bug within 35 days. They have colourful bodies. Their markings and shape changes after each moult. In the first larval stage (which lasts 3 days), they remain si... | | |
| | ... fertilized females lay their eggs in stagnant water which is often very muddy. Here, the oxygen content of the water plays a decisive role, as egg-laying can even take place in cesspools. From these eggs the so-called "rat-tailed maggots" hatch – larvae with a long breathing tube attached to the abdomen that extends up to the surface of the water. The larvae feed on decaying organic matter and thus make an important contribution to water clarification. | | |
| | | ...tus rufipes are active from the beginning of July to November and feed on grasses.
The fertilized females lay their eggs in summer or autumn in the root zone of plants or in the upper 2 cm of the soil layer. The eggs overwinter there. The larvae hatch in the spring and develop through four larval stages from June to November to become adults. | | |
| After mating, which (in each new generation) occurs approximately every 9 - 14 days, the fertilized females lay about 400 yellow-white eggs, 0. 5 mm in length, in fermenting organic material.
At what pointthe larvaehatch from their eggs, depends on the ambient temperature. The newly hatched larvae are segmented, have no feet, and are similar in shape to worms. They immediately start searching for micro-organisms (yeasts, bacteria), which they eat with the help of their mouth parts, which are housed in a telescopic proboscis made from...
...start searching for micro-organisms (yeasts, bacteria), which they eat with the help of their mouth parts, which are housed in a telescopic proboscis made from chitin. They breathe through two visible, protuberant tubes. Approximately 24 hours after hatching the larvae moult and thus reach the 2nd larval stage. After another 3 days, and 2 further larval stages, the development of the maggots ( now brownish in colour and about 3 mm in length ) is complete. They develop within their third skin into a b...
...val stages, the development of the maggots ( now brownish in colour and about 3 mm in length ) is complete. They develop within their third skin into a barrel-shaped pupa and remain there for 4 days. After that, the adult flies of the new generation hatch.
The short period of development and large number of offspring leads to a high density in the small fruit fly population, and this causes substantial losses to growing fruit as well as fruit in storage. On the other hand, the small fruit fly is ... | | |

They prey on insects and arthropods. This species is endangered. Birds and other insect eaters pose a threat, especially during mating.
The fertilized females lay their eggs in sand. When the larvae hatch, they dig a burrow, which is connected to the surface of the sand by a steep upward path. The larvae also feed on insects (on the sand’s surface) and they draw back into their dens when the temperature drops. | | |
| | The larvae hatch in September. They are nocturnal, but can also be found during the day on grasses. Their bodies are up to 75 mm in length and their colouration is very striking, almost unmistakeable. The basic body colour of the caterpillar is dark grey, and later ... | | |
| Malacosoma franconica prefer warm, sandy habitats. Although it is a moth, it can be seen in daylight. It is active from June to July. Mating takes place shortly after the moths have hatched from their pupae and may take up to two hours. Immediately afterwards, the fertilized females lay their eggs. The yellowish-white eggs are glued together inrings, using an adhesive brownish substance, onto the stems of plants such as common sorrel...
...ort plantain (Plantago lanceolata), Achillea, andworts (Minuartia), heron’s bill (Erodium), blackberry (Rubus), and Agropyron or dwarf everlast (Helichrysum arenarium). They overwinter like this.
In April of the next year, the hairy caterpillars hatch from the eggs and start to feed on their host plant. They are sociable at first and later solitary. | | |
| | ...e they are covered with yellowish hair. A blue to blue-grey line runs along their sides near the top. The black to blackish-brown colour of their head is difficult to see because of dense brownish hair. The caterpillars pupate in May in a cocoon and hatch as adult moths approximately one month later. | | |
