|Root-maggot flies are found worldwide. There are around 1,200 species globally and 220 in Central Europe. Root-maggot flies are small to medium in size and often have strong bristles. Some species have striking patterns in grey and black, others have yellow abdomens or yellow legs, however most species of root-maggot flies are rather unremarkable in appearance.|
|Root-maggot flies (Anthomyiidae) form a family in the order two-winged flies (Diptera), the suborder flies (Brachycera), the infraorder Muscomorpha (division: Schizophora, subdivision: Calyptrata) and the superfamily Muscoidea. They are divided into th...|
|The fertilized females lay their eggs on the host plants of the larvae, or in the soil. The larvae feed as rootworms or mostly as leaf miners. Some species of larvae can cause considerable damage when they infest crops. This includes in particular, species of the genus Delia (Delia antiqua, Delia coarctata, Delia Floralis, Delia platura, Delia radicum) and ...|
...iderable damage when they infest crops. This includes in particular, species of the genus Delia (Delia antiqua, Delia coarctata, Delia Floralis, Delia platura, Delia radicum) and the turnip fly (Pegomyia hyoscyami). The larvae of other species of root-maggot flies feed on fungus or rotting plant parts. Root-maggot flies overwinter in the soil as pupae.
|...flies and moths (Lepidoptera), the superfamily Pyraloidea, the family snout moths (Pyralidae), the subfamily Pyralinae and the genus Endotricha. Adult Endotricha flammealis reach wingspans of 18 - 23 mm. Their body is ochre in colour. Seam field and root field from midfield are insulated by a bright line with brownish edges. The front edge of the forewings is spotted with white. In the midsection there is a darker patch. |
|The Tetragnatha montana is the only species where the female has a small tooth near the root of its mouth parts (chelicerae). The rear section of the females’ body (opisthosoma) is a shiny silvery white colour on the upperside. In the middle is the characteristic leaf-like marking (folium). It is composed of a white surrounding area aga...|
|Root-maggot flies prefer to live on flowering plants, where they feed on the nectar and pollen. However, they also sometimes feed on liquid manure, sweat, blood or the watery discharge from wounds. Some species live on rotting seaweed, others reside in...|
|...positor is at the end of the female’s abdomen and has a telescope-like shape. There are also dark bristles on the flies’ abdominal segments. The wings are transparent. When the wings are outspread, two very short, parallel veins are visible near the root of the wings. The rear vein is weaker and often only looks like a fold. The legs are yellowish-beige. An identifying characteristic of Meiosimyza rorida is the row of black bristles located on the thighs of the first leg pair.|
|...dsides, slopes, forest clearings and edges of marshes, all of which are exposed to the sun. Omocestus 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. |
