Stiriinae is a zoological term referring to a subfamily of beetles of the family Staphylinidae, commonly known as rove beetles. The Staphylinidae family is one of the largest families of beetles, comprising more than 63,000 known species worldwide. The subfamily Stiriinae includes numerous species of rove beetles found in various habitats, including forests, grasslands, and even urban areas.
Rove beetles belonging to Stiriinae are generally small to medium-sized, elongated insects with a characteristic elongated and flexible abdomen. They have short wing covers that do not entirely cover the abdomen, exposing several visible abdominal segments. The antennae are usually long and segmented, providing the beetles with a keen sense of touch and smell.
Stiriinae beetles are largely predatory, preying on a wide range of invertebrates, such as insects, spiders, and other small arthropods. Some species of Stiriinae are also known to scavenge on decaying organic matter. They are primarily active at night and can be found in leaf litter, soil, under stones, or in other dark and moist habitats.
The classification and taxonomy of Stiriinae beetles are still evolving, as new species continue to be discovered and studied. These beetles play a vital ecological role in their respective ecosystems by contributing to nutrient cycling, controlling pest populations, and serving as a food source for other animals.
