Lampsis

Lampsis is a genus of beetles belonging to the family Cerambycidae, commonly known as longhorn beetles. These insects are primarily found in the Mediterranean region, with several species distributed across southern Europe, North Africa, and parts of the Middle East. The name "Lampsis" derives from the Greek word *lampros*, meaning "shiny" or "bright," which refers to the often iridescent or metallic appearance of their exoskeletons.

The most well-known species in this genus is *Lampsis nocturna*, commonly referred to as the Mediterranean longhorn beetle or the European longhorn beetle. This species is notable for its distinctive elongated antennae, which can be up to three times the length of its body, a characteristic feature of many cerambycid beetles. Adults typically exhibit a dark, often black or dark brown, body with metallic green or blue reflections, particularly on the elytra (wing covers). The larvae of Lampsis species are wood-boring, feeding on the xylem of various hardwood trees, including olive, fig, and mulberry.

Lampsis beetles play a role in forest ecosystems, though their larval stage can cause damage to agricultural and ornamental trees. They are occasionally considered pests due to their wood-boring habits, which can weaken or kill trees. Efforts to manage populations often involve monitoring infestations and removing affected wood to prevent further spread.

The life cycle of Lampsis beetles includes three main stages: egg, larva, and adult. Females lay eggs in small crevices or cracks in tree bark, and the larvae emerge to bore into the wood, feeding and developing over several months or years before pupating. Adults emerge in late spring or summer, where they mate and begin the cycle anew. Their presence is often associated with stressed or weakened trees, as healthy specimens are less likely to be targeted.

Conservation efforts for Lampsis species are generally not a priority, as they are not currently classified as threatened. However, their ecological role and potential impact on forestry make them a subject of interest for entomologists and arborists. Research into their behavior and life cycle continues to inform pest management strategies in affected regions.
