[i] In cases where it was not possible to estimate the population size, the numbers of captured individuals were italicized. “Density” denotes relative butterfly density (abundance) expressed as number of individuals per 1 ha of area.

Figure 2.
(a) The relationship between the relative density of butterflies and the coverage of invasive hawkweeds and (b) the ratio of coverage of invasive plants to the coverage of the butterflies’ host plant. Ph. teleius is marked in red, and Ph. nausithous is marked in blue. “Density” denotes relative butterfly density (abundance) expressed as number of individuals per one ha of area.
