Bark beetles are minute beetles found in forest and can make galleries directly into the heartwood of trees. As a part of research for controlling this pest insect, here we demonstrate the fine structural aspects of their external bodies of the bark beetle Ips acuminatus using the field emission scanning electron microscopy (FESEM). This beetle has well developed sensory system respond to both of visual and chemical stimuli. The mouthparts which consisted of a labrum, a pair of mandibles, a pair of maxillae and the labium are very effective devices for penetration and boring holes. The thorax contains a particularly hard exoskeleton and hard elytra including the powerful muscles that operate both the wings and legs. The beetle's exoskeleton is made up of numerous plates called sclerites, separated by thin sutures. This structure can provide strong armor of this beetle while maintaining flexibility.
