Nitidulids

Nitidulids, commonly known as sap beetles, are a family of small beetles belonging to the order Coleoptera. They are characterized by their relatively short, clubbed antennae and often oval-shaped bodies. Adult sap beetles typically range in size from 1 to 10 millimeters, with many species being much smaller. Their coloration varies widely, encompassing shades of brown, black, red, and yellow, and some species display intricate patterns. Larvae are generally grub-like and are often found in the same habitats as adults.

These beetles are saprophagous, meaning they feed on decaying organic matter, particularly sap, fruit, fungi, and pollen. Their presence is often associated with injured trees, fermenting fruits, and decaying plant material. Some species are considered pests due to their association with stored products or their ability to transmit fungal diseases to fruits, while others play a beneficial role in decomposition and pollination.

Nitidulids are found worldwide in a variety of habitats, from forests to agricultural areas. They are an ecologically diverse group with many different feeding habits and life cycles. Identification of specific species often requires close examination of morphological features.
