This record describes Otiorhynchus sulcatus (species). Recorded family: Curculionidae. Recorded order: Coleoptera.
Identification and Appearance

| Feature | Description |
|---|---|
| Additional details | Length Adults about 10 mm. |
| Elytra | Elytra black mottled with small brown patches, grooved, not shiny. |
| Antennae | Antennae relatively long. |
| Pronotum | Pronotum pebbly in texture. Unless identified by a recognised expert, good photos are required that show the key ID features. Also state the beetle's size in the comments box. Various habitats including parks, gardens and conifer nursery beds. They may even be seen trying to access buildings in colder months. Peak is summer and autumn with new adults emerging in summer. Half-grown larvae overwinter in the soil. The larvae are legless, white to pinkish in colour, and have brown heads. Both the adult and larval stages are damaging to seedlings. The adult weevils live above ground feeding on cotyledons and on the bark of seedlings at night. Root weevil larvae are subterranean, feeding on the roots of many kinds of plants including conifer seedlings in nursery beds. |

About Primitive Winged Insects: the wider group
Order-level background for Coleoptera, the group containing Otiorhynchus sulcatus. Species-specific details appear above.
Group overview
Coleoptera is the largest order of insects with over 400,000 described species, representing ~25% of all known animal species and ~40% of all insects. In the U.S. alone, nearly 30,000 beetle species have been identified.
Ecological role of the group
Beetles are prominent decomposers, especially in forests, breaking down dead wood and recycling nutrients. As predators, they reduce populations of pest insects. Many species are also important pollinators of flowering plants.
Economic and practical significance of the group
Beetles have major economic significance: leaf beetles (Chrysomelidae) and weevils (Curculionoidea) are among the most destructive agricultural pests globally, costing billions annually, while predatory species like ladybugs provide natural pest control.
Recorded sources for this group: Britannica, Smithsonian, NCSU Entomology. Imported estimates may describe particular regions or reporting periods.
