[R] Family of the order Coleoptera, sometimes considered as a subfamily of the Curculionidae, bearing close resemblance to the latter.
Adults small, cylindrical, generally strong fliers.
Larvae of most species xylophagous, excavating slender mines or burrows in the bark of trees or between the bark and sap wood, usually at right angles to the breeding or maternal chamber constructed by the adult.
Certain bark beetles depend on symbiotic fungi ("Ambrosia"): they prepare a bed or layer of chips and excreta, upon which the fungus develops, and feed on after this has digested the wood.
Among the species injurious to fruit trees include the (Phloeotribus scarabaeoides), the fruit bark beetle (Ruguloscolytus rugulosus) and the European shot-hole borer (Xyleborus dispar).
