What kind of bug is featured in the photo, and does it reproduce in or damage wooden structures?
Answer: Long-horned beetle
Lyle Buss, University of Florida entomologist, said that the bug is one of the long-horned beetles (family Cerambycidae) in the subfamily Prioninae. It is probably Mallodon dasystomus, the hardwood stump bore. Their larvae develop in the heartwood of various hardwoods like oak. If not that species, Buss said the beetle could be an Archodontes melanopus, which breeds in oaks, but more in the roots.
Though Jill found the long-horned beetle in the wall, Buss noted that both previously mentioned species are not structural pests, meaning they do not attack lumber or other wood products. They were most likely hiding there during the day. Buss also said there’s no need to worry about their laying eggs in the wall, either.
