Which statement about Lyctid powder post beetles is true?

1. Feed on hardwoods exclusively

2. Create large exit holes

3. Only attack softwood

4. Nest in old furniture

The correct answer is: Feed on hardwoods exclusively

Lyctid powder post beetles are known for their specialized feeding habits, which primarily involve hardwoods. This specificity means that they thrive on certain hardwood species, where they lay their eggs and the larvae subsequently feed on the starch found within the wood. This characteristic behavior is notable because it distinguishes them from other wood-boring insects that may target a broader range of wood types. The other options focus on different characteristics or behaviors that do not accurately apply to Lyctid powder post beetles. For instance, they do not create large exit holes; rather, the exit holes they create are typically small and round, often around the size of a pinhead. Additionally, their preference does not extend to softwoods, as this contradicts their known feeding habits, which exclusively involve hardwoods. Finally, while they can infest furniture, they do not typically nest in old furniture but rather within the wood structures themselves, laying eggs there. Thus, the truth about Lyctid powder post beetles firmly aligns with their exclusive feeding on hardwoods.
