Alydus

Alydus is a genus of longhorn beetles belonging to the family Cerambycidae. These beetles are primarily found in the Americas, with a notable diversity in South America. The genus was described by Francis Walker in 1859. Alydus beetles are characterized by their relatively slender bodies and antennae, which are typically longer than the body itself in males. Their coloration can vary, often featuring brown or black hues, sometimes with lighter markings or bands that aid in camouflage or mimicry. The larvae of Alydus beetles are wood-borers, feeding on decaying wood of various tree species. The specific host plants can differ depending on the species and geographical location. Adult beetles are often observed on or near their host trees, and their diet typically consists of pollen, nectar, or sap. Reproduction involves the laying of eggs on or in proximity to suitable larval food sources. Research on the precise ecological roles and specific life cycles of many Alydus species is ongoing, as is common with many insect genera with extensive distributions. The genus is part of the subfamily Lamiinae, which is the largest subfamily within the Cerambycidae.
