Life Cycle of A robber fly
Egg The eggs of a robber fly are typically laid in soil or on plant tissue. They are small, rounded, and exhibit little locomotion. Color varies but reflect camouflage to avoid predation. No feeding occurs.
Larva After hatching, a robber fly’s larvae are worm-like, lacking true legs and wings. They grow significantly through molting, change shape, and are voracious feeders, often predatory or scavenging in habit.
Pupal The pupa of a robber fly forms within a protective casing, ceasing feeding and movement. Metamorphosis occurs, reorganizing tissues into adult structures. Size remains fixed, but form drastically changes.
Adult Emerging from the pupa, the adult a robber fly exhibits a hardened exoskeleton and functional wings. The colors often become more pronounced, aiding in species-specific recognition and predator avoidance. Reproduction is now the primary function.

Habitat Preferences of A robber fly Through Different Life Stages
Eggs of a robber fly are typically laid in sandy or loose soil, often in open, sunny locations. The larvae burrow and reside in the soil where they prey on other small insects. As they grow, these larvae will frequently move to new locations underground seeking food. Pupation for a robber fly also occurs within the soil, where the pupal case will be found just beneath the surface. Adult a robber fly favor areas such as meadows, fields, or forest edges with abundant prey and perching spots, like twigs or rocks. To search for the various stages, one would inspect soil for eggs or larvae, excavate gently for pupae, and scan sunny, open habitats for adults.
