The nest beetles (Cholevinae) form a subfamily in the family of the Leiodidae , which are also referred to as sponge ball beetles in the broader sense. The nest beetles are by far the most species-rich group within the Leiodidae. Many species inhabit the nests of mammals , which is what gave them their German name.
features
The nest beetles are very small to medium-sized beetles that reach a length of 0.8 to 9 millimeters. They usually have an oval body and are brown or gray to black in color. The antennas are eleven-segmented, the eighth antenna segment is always smaller than the seventh and ninth. The last links of the antennae form a club. With a few exceptions, the nest beetles offer a relatively uniform appearance on the outside. It is often difficult to distinguish the individual species, for example in the shape of the antennae, the pronotum or the genital organs.
distribution
The types of the subfamily are represented on all continents with the exception of Antarctica . However, the main distribution area is in the western Palearctic . Many beetles from this subfamily are endemic to a small range , e.g. B. the Segeberger cave beetle , which is only known from the Kalkberg cave of Bad Segeberg in Schleswig-Holstein .
Way of life
Many species are roommates of mammalian nests and underground structures, including the species of the genus Choleva . Others are specialized cave dwellers . The majority of the species live on the ground, in the leaves or in the litter, but also on carrion , where they probably mainly feed on fungal spores. The proximity to the rotting animal carcasses was also the reason why the group was counted among the carrion beetles (Silphidae) until the first half of the 20th century .
