- Bookworm (insect)
Bookworm is a popular generalization for any
insectwhich supposedly bores through books.
Actual book-borers are uncommon. Both the
larvaeof the death watch beetle("Xestobium rufovillosum") and the common furniture beetle("Anobium punctatum") will tunnel through wood and if paperis nearby they will pass into that.
A major book-feeding insect is the booklouse (or book louse). A tiny (under 1 mm), soft-bodied wingless "
psocoptera" (usually "Trogium pulsatorium"), that actually feeds on molds and other organic matter found in ill-maintained works, although they will also attack bindings and other parts. It is not actually a true louse.
Many other insects, like the
silverfish("Lepisma saccharina") or cockroach(various "Blattodea"), will consume these molds and also degraded paper or the starch-based binding pastes – warmth and moisture or high humidity are prerequisites, so damage is more common in the tropics. Modern glues and paper are less attractive to insects.
Tineola bisselliella" and " Hofmannophila pseudospretella" will attack cloth bindings. Leather bound books attract various consumers, such as " Dermestes lardarius" and the larvae of " Attagenus unicolor" and " Stegobium paniceum".
The bookworm moth ("
Heliothis zea" or "H. virescens") and its larvae are not interested in books. The larvae are pests for cottonor tobaccogrowers as the cotton bollwormor tobacco budworm.
