clerid

Clerid is a common term used to refer to members of the family Cleridae, which is a large and diverse group of beetles. These beetles are also known as checkered beetles or sap beetles. They are found worldwide, with the greatest diversity in tropical and subtropical regions. Clerids are characterized by their often brightly colored and patterned elytra, which can be metallic or iridescent. Their bodies are typically elongated and somewhat flattened.

The larval stages of clerids are often predatory, feeding on the larvae of other insects, particularly wood-boring beetles. Some clerid larvae are also parasitic. Adult clerids have varied diets, with many being predatory, feeding on other insects, especially those found in decaying wood or on flowers. Some species are important biological control agents, helping to regulate populations of pest insects. Others feed on pollen or nectar.

The family Cleridae contains over 3,500 species in more than 300 genera. They play significant roles in their ecosystems, both as predators and as consumers of plant material or pollen. Their striking coloration serves as aposematism, warning potential predators of their unpalatability or toxicity. While many clerids are beneficial due to their predatory habits, a few species can become pests in certain contexts, though this is less common. The study of clerids is part of entomology, contributing to our understanding of insect biodiversity and ecological interactions.
