FIGURE 2. Species group coverage for breeding host data by island. White portions indicate the proportion of species with at least one rearing record, gray the proportion with no records. Numbers under the pies are the number of species for that group present on the island. Numbers under each island do not add up to the "all islands" total due to the existence of multi-island species. Note that proportion of species with records refers to the number of species inhabiting the island that have data from anywhere; thus a species inhabiting both Maui and Moloka'i will be counted as having rearing data under both columns even if data only come from Maui. Data for Lâna'i is not shown because it had so few rearing records (23 records for 17 species), and is poorly collected in general. All figures are for described species only.
