Pyrrhonotus

Pyrrhonotus is a genus of beetles in the family Cerambycidae, commonly known as longhorn beetles. These beetles are characterized by their elongated antennae, which are typically at least as long as their body. The genus Pyrrhonotus is found in Australia and includes several species, though it is not a particularly large or diverse genus.

The larvae of Pyrrhonotus beetles are wood-borers, meaning they feed on wood as they develop. They typically bore into dead or dying trees, and their presence can sometimes be an indicator of forest health. Adult beetles are usually observed on or near their host trees. Their diet as adults can vary, but often includes pollen, nectar, or leaves.

Specific details about the life cycle, host plant preferences, and geographical distribution are often documented in entomological literature for individual species within the Pyrrhonotus genus. Research on these beetles contributes to the broader understanding of Australian insect biodiversity and forest ecology. Their appearance can vary between species, with some exhibiting muted brown or grey coloration, while others may have more striking patterns.
