Country Diary: Insect glistens in sunlight like a sparkling gem
“Lost a screw?” we enquired of our cabinet-maker pal Martin, as he carefully swept amongst oak wood shavings. No, apparently he saw a grub in a tiny hole, and poked it out. Upon examination, it proved to be the larvae of a death-watch beetle! Woodworm does great damage tunnelling through household timbers. This species is larger that the furniture beetle, usually breeding in oak timbers, especially if damp. Its exit holes are three to four mm across. It’s well known for the tapping sound make by the adults before they emerge.
