Hesperophanes melonii, an endemic species to Sardinia, has been described from Cagliari environs by Luca Fancello and Davide Cillo in 2012 [❖]
Unlike the sister species Hesperophanes sericeus (Fabricius, 1787), which attacks mainly dead wood of various tree species,
larva of H. melonii creates its gallery inside the wood of living host plant (Arthrocnemum fructicosum). Larvae feed mostly in the root system, but
sometimes development takes place above-ground parts of the host plant (approx. to a height ca 10 cm above the ground level). Within the extensive
formations of A. fructicosum present in the type locality, the beetle attacks a low percentage of plants, which are very difficult to identify
as they looks perfectly intact and without obvious signs of suffering. The environment colonized by H. melonii is a complex of relatively small localities
along the western bank of the Stagno di Cagliari, characterized by salty soil. The species is distributed in area with presence of brackish water and is
dependent on halophilic plant population (Arthrocnemum fructicosum) [❖].
