This version includes a cover letter written by Kulman to distribute the article to colleagues (final page of the PDF).A speculative overview of butterfly production management is presented which includes manipulation of habitats to enhance larval and adult food plants, accessibility and longevity of adults, early season introduction of migrants, and use of exotic butterflies and larval host plants. Concentration and accessibility of butterfly adults for viewing and collecting may be influenced by adult longevity, adult food sources, larval host plant odors, and other factors. Dangers to butterflies and their host plants by concentrating adults are discussed. Production management opportunities by manipulation of larval host plants appears to be much greater for expansion of the local and regional range of butterflies than for increasing butterfly density. The paucity of the literature does not permit general conclusions concerning population regulating factors, carrying capacity concepts, etc. However, there is sufficient observational data to guide experimental production management studies. Migratory species are considered for management although the carryover from management inputs are lower than with resident butterflies. Introduction of exotic species is limited mainly to butterflies useful in weed control programs. Speculative production research possibilities are given for the Pipevine Swallowtail, Battus philenor ( L.); Black Swallowtail, Papilio polyxenes asterius Stoll; Giant Swallowtail, Papilio cresphontes Cramer; Little Sulphur, Eurema lisa (Boisduval and Le Conte); Dainty Sulphur, Nathalis iole Boisduval; Baltimore, Euphydryas phaeton (Drury); and Monarch, Danaus plexippus ( L.).en-USArticle
