The term woodboring beetle encompasses many species and families of beetles whose larval or adult forms eat and destroy wood (i.e., are xylophagous). [1] In the woodworking industry, larval stages of some are sometimes referred to as woodworms. The three most species-rich families of woodboring beetles are longhorn beetles, bark beetles and ...
Wood affected by woodworm. Signs of woodworm usually consist of holes in the wooden item, with live infestations showing powder (faeces), known as frass, around the holes.. The size of the holes varies, but they are typically 1 to 1.5 millimetres (5 ⁄ 128 to 1 ⁄ 16 in) in diameter for the most common household species, although they can be much larger in the case of the house longhorn beet
Longhorn beetle. The longhorn beetles (Cerambycidae), also known as long-horned or longicorns (whose larvae are often referred to as roundheaded borers), are a large family of beetles, with over 35,000 species described. [2] Most species are characterized by antennae as long as or longer than the beetle's body.
Identification of which insect is present in interior timbers is difficult; by their nature, the larvae are tucked away from sight in their galleries. The presence of wood-boring insects may be indicated by frass (fecal residue) and fresh dust. Recent exit holes often have bright rims, while the rims of older holes have become dull.
Powderpost beetle. Powderpost beetles are a group of seventy species of woodboring beetles classified in the insect subfamily Lyctinae. [] These beetles, along with spider beetles, death watch beetles, common furniture beetles, skin beetles, and others, make up the superfamily Bostrichoidea. While most woodborers have a large prothorax ...
Buprestidae is a family of beetles known as jewel beetles or metallic wood-boring beetles because of their glossy iridescent colors. Larvae of this family are known as flatheaded borers. The family is among the largest of the beetles, with some 15,500 species known in 775 genera. In addition, almost 100 fossil species have been described.
Appearance. Like many other species in the family Cerambycidae, R. funebris has strikingly colored wing covers (elytra). The elytra are dark with three white bands. The thorax (pronotum) is white with a large black spot. The alder borer's antennae are banded white and black. The male's antennae are longer than the body; the female's are shorter.
Only for few species the larval biology is known. Orussidae are parasitoids of xylobiontic larvae of beetles or Hymenoptera, particularly of the larvae of jewel beetles (Buprestidae), long-horned beetles (Cerambycidae), and wood wasps (Siricidae, Xiphydriidae). [6][7] Orussids can be observed running around quickly on dead tree trunks.
