Less is known about their larvae They 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. | | |

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. | | |
| | Booklice | | The booklice (Psocoptera), also called barklice or barkflies, are an order in the class insects (Insecta), the subclass winged insects (Pterygota) and the infraclass Neoptera.

| | Cobweb spiders which live mostly sedentary lifestyles can live a long time. They spin large webs and catch insects at night. Sometimes they hunt for insects on plants or whilst on the ground. Their webs are labyrinth like and are created like cobs.
