The Black Lordithon Staphylinid Beetle is a member of the rove beetle family Staphylinidae, one of the largest beetle families in the world. Rove beetles are known for their elongated bodies and short wing covers that leave much of the abdomen exposed. These beetles are typically beneficial insects because they prey on other small arthropods and pests.
Identification
Black rove beetles usually measure between 1/4 and 3/4 inch in length. They have slender bodies, short wing covers, and flexible abdomens that often curve upward when the beetle is disturbed. Their coloration is typically shiny black or dark brown. Unlike many other beetles, the exposed abdomen gives them a distinctive appearance that resembles an earwig.
Distribution and Habitat
Rove beetles are widely distributed throughout North America and are commonly found in gardens, forests, compost piles, and under leaf litter. They prefer moist environments where prey insects are abundant.
Life Cycle and Behavior
The life cycle includes egg, larva, pupa, and adult stages. Both larvae and adults are predators that feed on small insects such as fly larvae, mites, and other soil-dwelling pests.
Pest Status
Black rove beetles are beneficial insects because they help control pest populations. Occasionally they may wander indoors but they do not infest homes or cause structural damage.
Prevention
- Seal gaps around doors and windows.
- Reduce moisture around foundations.
- Keep organic debris away from building entrances.
Control
Control is rarely necessary. Beetles that enter homes can simply be removed or vacuumed.
