Life Cycle of Large rove beetle
Egg The development of large rove beetle begins as an egg, which is usually laid in a protected environment. The egg is small, often oval-shaped, and can vary in color, but generally blends into its surroundings.
Larva After hatching, the larva of large rove beetle emerges, with a body that can be elongated and segmented, showing little resemblance to the adult. It usually lacks wings, has a distinct head with chewing mouthparts, and is often voracious, feeding to accumulate energy for subsequent stages.
Pupal The pupa represents a transitional stage where large rove beetle undergoes significant transformation. During this phase, the creature is typically immobile and can be encased in a cocoon or puparium. Its color and shape are distinct from both the larva and the adult, and the developing wings and adult body parts can often be discerned within the pupal case.
Adult Emerging from the pupa, the adult large rove beetle’s development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction. It often exhibits a significant change in form and function from the larval stage, with the adult often being a more efficient disperser and sporting different color patterns.

How and Where Can You Find Large rove beetle at Different Life Stages
Larva To find large rove beetle larvae, search in soil, under stones or within decaying organic matter such as leaf litter or dead wood. They are more likely to be found in moist environments, so focus on areas with good soil moisture.
Pupal Finding large rove beetle pupae would involve looking at similar habitats as the larval stage since many beetles in the Staphylinidae family pupate within or close to their larval feeding grounds. Carefully sift through soil or leaf litter in shaded and humid areas.
Adult Large rove beetle adults are typically found on the ground or occasionally on vegetation. Search for them by exploring areas with abundant undergrowth or by turning over stones and logs. At night, large rove beetle adults can sometimes be attracted to light, so using a light trap could be an effective method.
