Trophic spectrum

What are oligophages, monophages, polyphages-this is clear. I would like to clarify in which case the oligophagus is narrow, and in which case it is wide. And so it is for all three terms. There is a certain number of plants, for example, to consider the oligophagus wide. Let's say polyxena, the larva feeds on kirkazon, several species-it turns out a wide oligophagus. A narrow polyphage is like when a species feeds on 2-3 plant families. It looks like a polyphage, but narrow.
I would like to hear a clear definition of the three terms that apply to wide and narrow. I need an answer very urgently. I need a trophic spectrum for my diploma, but I do not know how to divide the species into groups.

different authors apply different criteria. And they can also be different for different groups. There is no specific scheme for all insects. I would take a textbook on insect ecology and adopt one scheme and stick to it. I can't tell you anything more specific right now...

I'm interested in daytime butterflies, if there's anything you can tell me. But thanks anyway.
