The bandit is one such specialist, though a very selective one, in that he feeds upon very few prey-types (oligophagous), mainly upon his own species, some varieties of ruminant (primarily cattle, sheep and goats) and the horse.
The terms "oligophagous" and "monophagous" have been used to describe specialists showing progressively greater fidelity in their choice of host plant(s), but unfortunately these terms have been used with little consistency (see summary in May & Ahmad, 1983).
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.g., Denno and Dingle 1981; Gould 1983; Mitter and Futuyma 1983; Futuyma and Peterson 1985; Diehl and Bush 1989; Carroll and Boyd 1992).
In contrast, many non-pest species are monophagous or oligophagous (Byrne & Bellows 1991).
femorata are oligophagous specialists, on Solanaceae and Asteraceae respectively.
Thus, it is probable that, when the insect fauna associated with single host plant is analyzed, free-feeding insects (generally with more oligophagous feeding habit) are more dependent on habitat characteristics, while galling insects respond more finely to specific host plant attributes (Koricheva et al.

They were considered oligophagous. With only a few exceptions, the host plants of the oligophagous beetles are taxonomically related.
