Species Profile
Mesosa curculionoides is a species of beetle in the family Cerambycidae, and the type species of its genus. It was described by Carl Linnaeus in 1761, originally under the genus Cerambyx. It has a wide distribution throughout Europe and in the Caucasus, and is also known from South Korea. It was formerly found in Belgium, where it is now extinct. It measures between 10 and 17 mm.
Mesosa curculionoides faces severe population decline primarily due to habitat loss from deforestation and forest fragmentation, which destroys the mature beech trees essential for its larval development. The species' highly specialized ecology, requiring specific host trees and forest conditions, makes it extremely vulnerable to environmental changes and human disturbance.
