A bark beetle is one of about 6,000 species in 247 genera of beetles in the subfamily Scolytinae.[1] Previously, this was considered a distinct family (Scolytidae), but is now understood to be specialized clade of the "true weevil" family (Curculionidae).[2][3] The common name refers to the fact that most species feed and develop in the inner bark (phloem and cambium layers) of tree stems, and the group probably originated from ancestors that fed in the inner bark of conifers.[4][5] However, the subfamily also has many species with other lifestyles, including some that tunnel into wood, twigs, fruit, seeds, or herbaceous plants.[1] Thus, the term "bark beetle" may refer to the taxonomic group (any species in the subfamily Scolytinae) or more narrowly to those species in Scolytinae that feed in the inner bark.[2] The group is often referred to more broadly as bark and ambrosia beetles[6][7], or simply scolytines.
