📖 1. Overview
The citrus longhorn beetle is a longhorn beetle native to Asia that damages over 100 species of trees, including citrus, earning it the English name citrus long-horned beetle.
🦴 2. Anatomy & Morphology
Its glossy black body is scattered with white to pale yellow spots, and the base of each segment of its long antennae is white or pale blue. Females measure about 38 mm, males about 25 mm, and the male's antennae are twice the length of its body.
🔍 3. Ecology & Behavior
Eggs are laid in crevices of trunks or exposed roots, and larvae bore between the phloem and xylem of trunks and roots. Its life cycle usually takes 1 year, and after emerging, adults feed on leaves and tender twig bark for 10–15 days before mating.
🇰🇷 4. Connection to Korea
It is listed on the National List of Species of Korea, and Rural Development Administration materials record its domestic distribution as nationwide and note that adults can be seen on willow trunks from late spring to autumn (under the name Anoplophora malasiaca).
