The three most species-rich families of woodboring beetles are longhorn beetles, bark beetles and weevils, and metallic flat-headed borers. Woodboring is thought to be the ancestral ecology of beetles, and bores made by beetles in fossil wood extend back to the earliest fossil record of beetles in the Early Permian ( Asselian ), around 295-300 ...
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
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.
The Asian longhorned beetle is a wood-boring insect that attacks 12 types of hardwood trees in North America, including maples, elms, buckeyes, birches and willows. Infested trees do not recover ...
Lyctus carbonarius is a wood-boring beetle in the family Bostrichidae (formerly in the family Lyctidae, which is now a subfamily of Bostrichidae), commonly known as the southern lyctus beetle. It is a serious pest of hardwoods including ash, hickory, oak, maple and mahogany and can infest many products in the home including hardwood flooring ...
Powderpost beetles feed on deciduous trees, including certain hardwoods or softwoods depending on the species. Some hardwoods are naturally immune if they have low starch content or if their pore diameters are too small for the female beetle's ovipositor to lay her eggs in. Wood preservatives can be used to
The female lays her eggs in cracks in wood or inside old exit holes, if available. The eggs hatch after some three weeks, each producing a 1 millimetre (0.039 in) long, creamy white, C-shaped larva. For three to four years the larvae bore semi-randomly through timber, following and eating the starchy part of the wood grain, and grow up to 7 ...
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. [1]
