Abstract
At least 10,000 species of leafminers in four orders of insects (Lepidoptera, Diptera, Coleoptera, and Hymenoptera) are found worldwide. The common feature of all leafminers is that larvae feed within leaves for at least some larval stages. Larvae of facultative mining species feed internally but also externally as free-feeders, usually in later larval instars. Larvae of obligate mining species feed exclusively, and may also pupate, within leaves (Hering 1951, Powell 1980). Despite wide interspecific variation in life histories, leafminers are generally more closely associated with their feeding substrates than are free-feeding insects (Mattson et al. 1988). This "intimacy" (sensu Mattson et al. 1988) is the primary factor in directing their evolution and influencing population dynamics.
