Pterolophus

Pterolophus is a genus of longhorn beetles belonging to the family Cerambycidae. These beetles are primarily found in South America, with most species documented in Brazil and surrounding countries. The genus is characterized by its relatively small to medium size, typical of many Cerambycidae, and distinctive antennae that are often longer than the body, a common feature of longhorn beetles.

Species within Pterolophus exhibit a range of color patterns, often featuring cryptic coloration that aids in camouflage against bark and foliage. Their larval stages are xylophagous, meaning they feed on wood. They typically bore into dead or decaying timber, contributing to the decomposition process in their native ecosystems. Adult beetles are often observed on host plants, where they feed on nectar, pollen, or sap.

The taxonomy of Pterolophus has been subject to revision over time, with new species being described and existing ones reclassified. Research continues to shed light on their distribution, host plant associations, and ecological roles. Their presence is an indicator of forest health and biodiversity within their geographic range.
