Host specificity in ACG Microgastrinae. (A) Frequency histogram illustrating the number of host species of caterpillars used by each provisional species of wasp. (B) The number of provisional species of wasp using barcodes that are contained within each morphospecies of wasp. (C) CO1 NJ tree for 8 provisional Apanteles wasp species that are morphologically Apanteles leucostigmus (species 17 through 28). Accessions for the wasp and host species imaged are detailed in SI Appendix, Section 2. The 3 cases marked by an asterisk indicate a wasp whose host records include more than 1 species of host, but these species are all closely related species with nearly identical ecology. (D) NJ tree for 28S for same species presented in C and using a consensus sequence for each species (the number of identical sequences used is in parentheses).
