Meaning at a glance
- Primary sense: Eating many types of food.
- Grammar: polyphagous is listed as adj.
- Nearest alternatives: omnivorous.
- Useful contrasts: monophagous.
- Usage evidence: Animals show various degrees of adaptation aimed at taking advantage of available resources, but. . . most can be considered either specialists or generalists. Among plant-eating insects the more specific terms polyphagous, oligophagous, and monophagous are widely employed in relation to the variety of plant species they use. The majority of phytophagous insects are oligophagous. While they differ in their behavior from monophagous insects (which feed on only a single plant species), they are selective as far as which plant families or genera are acceptable. Other factors besides nutritional composition of the plant are important in guiding their behavior. Specialist animals exploit a particular resource: perhaps a particular plant part such as leaves or fruit, or perhaps a single plant species. . . By contrast, humans are extreme generalists. Like other omnivores such as rats, bears, pigs, and many primates, we eat a range of animal and plant foods. For omnivores, not only sensory perception but also the lessons learned from the physiological consequences of ingestion are important in determining food selection.

Definition decision workflow

Check whether "polyphagous" is acting as adj in your sentence. A definition is only useful when the grammar matches the way the word is being used.
2. Test the nearest option
Compare it with "omnivorous" and other nearby choices to see whether the sentence needs a softer, stronger, or more familiar word.
3. Confirm with context
Use the example sentence below as an evidence check, then read your own sentence out loud to catch tone or rhythm problems.
Review note: Definition pages are checked for source coverage, sentence evidence, synonym support, and editorial insight before they are treated as approval-ready pages. If the evidence is too thin, the page remains available to users but is kept out of the approval-facing indexed inventory.
Final meaning check
Before publishing a sentence with "polyphagous", ask whether the word helps the reader understand the idea faster. A precise word should reduce confusion, not simply make the sentence look more polished.
When the definition, synonym evidence, and example context point in the same direction, the word is usually a safer choice. When they conflict, revise the sentence or choose a clearer alternative.

"2024 WA Government Department of Primary Industries and Regional Development: Agriculture and Food Polyphagous shot-hole borer Euwallacea fornicatus is a beetle native to Southeast Asia. The beetle attacks a wide range of plants by tunnelling into trunks, stems and branches. Polyphagous shot-hole borer has a symbiotic relationship with a Fusarium fungus, farming it inside the tree as a food source for the beetle and its larvae. In susceptible trees, the fungus kills vascular tissue causing Fusarium dieback and tree death."
