The stub beetles (Endomychidae) are a family of beetles .
features
The beetles are between one and 7.5 millimeters long and have oval to elongated bodies, some of which are strongly arched upwards. The surface of their chitinized body can be very different. Either they are heavily or slightly downy hairy or hairless, but there are also species that have hard and dark bristles, whereby the range also extends from strong to unbristled. In addition, the body of some of these species is scaled. The pronotum is at its widest point, directly on the border with the abdomen, only slightly narrower than this. Their antennae have eight to eleven segments, only species of the genus Trochoidus have four segments. The length of the antennae varies from short to maximum body length, with one to three segments thickened to form a club at the end. The legs have either all four of equal length Tarsus , or they have every four, but of which the third member is shortened and is overlapped by the second Tarsenglied, or all legs have three Tarsenglieder. The limbs are double-lobed. The beetles either have well-developed, stunted, or no wings at all , with fringed or fringed rear edges.
The stubber beetles form a very diverse family, some species can be confused with the closely related ladybirds (Coccinellidae). The distinguishing features of the ladybirds are their tubular elongated, curved part of the male sexual organ ( sipho ), the lack of the bridge of the tentorium , a skeletal structure in the head and their shorter antennae, which are more clearly club-shaped at the end.
Way of life
Both the adults and the larvae live on mycetophagus from fungi and molds . They live in rotting plants, wood or in the fruiting bodies of mushrooms.
