Broad-nosed Weevil
Scientific Name: Often in genera like Otiorhynchus, Polydrusus, Trachyphloeus, or similar broad-nosed weevil genera; precise species identification requires closer examination.
Order & Family: Order: Coleoptera, Family: Curculionidae (subfamily Entiminae, or a related broad-nosed weevil family like Brachyceridae, depending on specific morphology)
Size: Typically 3 mm to 15 mm in length, depending on the specific species. The one pictured appears to be on the larger side of this range.
Natural Habitat
Broad-nosed weevils are found in diverse habitats including gardens, agricultural fields, forests, and other areas where host plants are present. Some species can be found indoors if they accidentally wander in.
Diet & Feeding
Adults feed on the foliage, bark, and flowers of a variety of plants. Larvae typically feed on plant roots.
Behavior Patterns
Adult weevils are generally slow-moving. Larvae of broad-nosed weevils typically feed on roots underground, while adults feed on foliage. Many species are nocturnal, hiding during the day and feeding at night. They may feign death when disturbed.
Risks & Benefits
Potential risks include being pests in agriculture and horticulture, as both larvae (root feeders) and adults (foliage feeders) can cause damage to plants. They rarely pose direct risks to humans. On the benefit side, they are part of the food chain, serving as a food source for birds and other predators. They also contribute to decomposition as part of the ecosystem.
