Towards the end of each segment the stripes develop into a triangle. The segments can also be yellow-brown, reddish-brown or pure yellow in colour and the stripes can be brown instead of black, or completely missing. The first abdominal segment (propodeum) usually has dense and dotting hair on its su... | | |

In vegetable plantations, chilli plants and potatoes are often affected. The females use their ovipositors to drill into the upper side of leaves and place 50 to 100 (sometimes even up to 400) eggs there. The hatched larvae develop rapidly. At the end of the third and last larval stage the bodies of the larvae can reach lengths of up to 3 mm. The bodies are yellowish-white in colour and have no legs. The larvae remain in the leaf and bite twisting (serpentine like) passage...
...e like) passageways into the cell tissues by moving their mouth hooks up and down. Hence the English name "Serpentine leafminers" for the genus Liriomyza. The outer layer of the leaves remains intact.
After 4 days the larvae are fully developed and leave the leaves’ interior, through a slit, in order to pupate. The development from egg to pupae (reddish-yellow to brown in colour) to adult takes about 17 days.
Endoparasites are natural enemies of the Chrysanthemum leaf miner larvae, for example, the larvae of the ichneumon wasps Dacnusa sibirica and Diglyphus isaea...
...t humans, the Chrysanthemum leaf miner ( is regarded as a pest when encountered in greenhouses and plantations, especially en masse as they can cause significant damage and crop yield losses. Pesticides are of little use as leaf-miner flies have developed a resistance to the poison and it only kills more of their natural enemies.

When larger populations occur in a limited space, social communities can develop, in which cobweb spiders combine their webs with those of their neighbours. | | |

This can be completely absent on the body of the males. The females have two white spots which develop with age into two broad stripes. Near the outer sex organ (epigyne) - the females have a white spot, flanked by bright stripes. | | |
| | Hylemya strenua are active from May to September in wet meadows, forest edges and gardens where they are found on flowers and on cattle or horse manure. The fertilized females lay their eggs on dung. The larvae hatch immediately and develop in the feces, feeding on the substrates. | | |
| | After mating, the fertilized females lay their eggs on the food plants of their larvae. The larvae develop in decaying plants, rotting fungi, and are also sometimes found in bird nests. After pupation, they overwinter in the soil. | | |
| | Adult Stictoleptura cordigera visit flowering plants, especially Umbelliferae (Apiaceae). The larvae of the beetle develop in the decaying wood of deciduous trees. | | |
| | The larvae of scarabs live in the soil, are C-shaped and known as grubs. They reach up to 70 mm in length and need 3 weeks to 5 years to develop from egg to chrysalis, depending on the species. | | |
| | Adult Sicus ferrugineus reach body lengths of 8 - 14 mm. The body size depends on the size of the host in which the larvae develop. The essentially rust-red body colour is sometimes black-brown, yellow, brown or reddish- brown. | | |
| | Scarlet dragonflies are active from April to October. They prefer to live on warm stagnant water (lakes, ponds or pools), where their larvae can develop. The presence of abundant vegetation on the ground at the water's edge is always importantbecause the males like to be there. | | |
