The host plant most often used locally by an oligophagous
insect is not necessarily the most preferred one when the favored host is rare (Singer et al.

For an oligophagous
insect, a host shift may alter selection on host-use traits in the colonizers and in their descendants, and indeed phenotypic divergence of populations on different host plants has been observed in a number of cases (e.
