A hoverfly (family Syrphidae) and a Spotted Cucumber Beetle (Diabrotica undecimpunctata) chow down on pollen together (Iowa, USA).
Oak Timberworm beetle, Arrhenodes minutus, at my light last night (Iowa, USA). Unlike the highly speciose "true" weevils, family Curculionidae (with 2,900+ species in North America alone and 50,000+ worldwide), the straight-snouted weevils (Brentidae, pictured) contain a modest 150 species in the states and 4,000 in total.
