They are a broad family belonging to the Coleoptera. Recognizing their activity is simple as they leave holes in the wood. If woodworms are active they leave sawdust sludge. They experience complete metamorphosis.
In Spain there are three main groups: Anobiidae, Lyctidae and Cerambycidae.
Anobiidae are popularly known as “woodworm”. Their size is 4-7 mm. The best known are Anobium punctatum, who usually like conifers and hardwoods. The adults emerge from April to August, and the output size of the orifice of adults is 1.5-2 mm.
Another well-known species are Xestobium, popularly recognized as “Death Clock.” The size of the orifice in adults is 3-4mm. It’s larger than the previous one (6-9mm) and life cycle is 5 to 10 years.
Lyctidae are also known as “wood borers” or “Piers Drill” Here in Spain we have two main species: Lyctus lineaeris and Lyctusbrunneus. Their life cycle is 1 year and their size is between 2-6 mm. They attack soft wood with high moisture content (10% -30%).
Longhorn beetles are by far the largest beetles (10-20 mm). The best known is Hylotrupes Bajulus, usually called “domestic capricorn”. The orifice in adults is oval and measures 7-10 mm. Their lifespan can reach 15 years. Their origin is Northern Africa and from there it has spread throughout the world. They prefer softwood.
Hylotrupes are the woodworms that can cause more damage to wood and, in many cases, they cause irreversible situations.
