...pproximately 7100 species found throughout the world, 80 species of which exist in Germany.
Some examples of these species are: Andrenosoma albibarbe, Andrenosoma atra, Aneomochtherus flavicornis, Antipalus varipes, Antiphrisson trifarius, hornet robberfly (Asilus crabroniformis), Choerades femorata, Choerades fimbriata, Choerades fuliginosa, ginger robberfly (Choerades gilva), Choerades ignea, golden-haired robberfly (Choerades marginata), Choerades rufipes, Cyrtopogon lateralis, Didysmachus picipes, violet black-legged robberfly (Dioctria atricapilla), Dioctria bicincta and scarce red-legged robberfly (Dioctria cothurnata).
Robber flies are, on average, 10-20 mm in length, the smallest being 3-4 mm and the longest 65 mm. What is remarkable about these flies are their long, strong legs which they use to capture prey.
Adult robber flies’ ways of living are as varied as their biodiversity. Robber flies can be encountered in different habitats, from forests to sandy areas.

...y live in soil or in the woods and, like the adult flies, feed on other insects and their larvae (mainly on scarab beetles’ larvae, or on the larvae of beetles which live in wood). The larval stage takes 1-2 years before the larvae pupate.
Adult robber flies ambush other insects in flight. For this purpose they perch and wait. . If an insect is flying in their vicinity, the robber fly flies up into the air, attacks and stings. | | |
| | Dune robberfly | | The dune robberfly (Philonicus albiceps) belongs to the family robber flies, in the order Diptera. In Germany, they are commonly found in moraine landscapes (a mass of rocks and sediment swept along and deposited by a glacier), especially in the northwest, as well as in sandy riversides or dunes.
The dune robberfly reaches body lengths of 13-20 mm. The abdomen is grey; the upper surface is covered with large brown spots. The legs are long, strong, and black.
Dune robberflies live in sandy places. They prey on other insects and are very good hunters. They often sit on the bare, hot sand waiting for their prey which they catch and sting in the air.
The dune robberfly is active from June to September. The females have a ring of spikes at the end of their ovipositors which they use to make a hollow in the sand to lay their eggs in. The larvae usually move deeper into the sand after hatching. | | |
