Patterns of Host-Plant Use
A continuous spectrum exists between insect species that will only feed on one plant species and others that feed on a very wide range of plants in many different families. It is usual to separate the insects into categories depending on their host-plant ranges, but it is important to recognize that no clear boundaries separate these groups and different authors use them in different ways. The categories commonly recognized are: monophagous, oligophagous and polyphagous.
