Katja Hora provides empirical data on the genetic architecture of host specialisation in phytophagous insects. A detailed understanding of the genetic architecture underlying diversification in host use can help to estimate the likelihood of ecological speciation. Hora presents empirical data on the nature of the inheritance of host use traits that differ between species of the small ermine moths (Yponomeuta), which are highly specialised on their host plant. The collective evidence of the various aspects of host use indicates that in Yponomeuta, speciation is based on a complex genetic architecture.
