How Long Can Anobiid Beetles live in Wood ?

B)  3-4 years

C)  4-5 years

D)  5-6 years

Answer:  C) 4-5 years

Adult beetles mate during July and August, and females soon lay 10 to 30 eggs singly or in groups of 2 to 10 within natural depressions of wood.

Eggs hatch in about 3 weeks, and newly emerged larvae bore directly into wood or, quite commonly, leave the oviposition site to find a more suitable place to feed.

Anobiids may spend 4 to 5 years in the larval form feeding on wood.
