Pollen beetle
beetles with dedicated adaptations for a diet of pollen
Pollen beetle is an informal term for any species of beetle associated intimately with suitably pollen-rich species of flowers. Typically such a beetle is adapted to the pollen as a major part of its diet. Species in at least sixteen families of the order Coleoptera could be counted as pollen beetles, and "pollen beetle" also is a common name for some such species.
Pollen feeding
Many insects of small to modest size benefit from feeding on pollen of suitable plants; pollen tends to be rich in protein, plentiful in season and easily available. Many plants, such as some members of the Araceae and Zamiaceae, produce large amounts of nutritious pollen, while producing little or no nectar. The pollen of such plants attracts and nourishes specialist pollen feeders that perform pollination, and many of those pollen feeders are beetles. In accessing the pollen of such plants, many pollen-feeding insects form mutually beneficial ecological relationships. Others damage the flowers however, reducing seed set, and harming the crop rather than benefiting it.
The nutritious Pollen from plants adapted to such pollinators contrasts with the also copious pollen from specialist anemophilous plants. Strict anemophiles commonly produce pollen that is low in nutritive value, since it is not adapted to attract or feed pollinators.
Begin with the source’s own compact description: “Pollen beetle” is beetles with dedicated adaptations for a diet of pollen. The dossier treats that line as a proposition to test through Pollen, beetle and beetles, not as a finished interpretation.
Why this record matters
The phrase “beetles with dedicated adaptations for a diet of pollen” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Feb 24, 2021. The linked authority identifier is Q18389256. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
