Broad-nosed Weevil (likely a type of Black Vine Weevil or similar)

Natural Habitat

Adults are often found in gardens, nurseries, and wooded areas, feeding on foliage at night. Larvae live in the soil and feed on plant roots.

Diet & Feeding

Adult weevils feed on the leaves of a wide range of plants, including ornamentals, fruits, and vegetables, creating characteristic notch-shaped damage on leaf margins. Larvae feed on plant roots and tubers.

Behavior Patterns

They are primarily nocturnal, feeding at night and hiding during the day. Adults are flightless but can walk considerable distances. Larvae are C-shaped, legless, and white, residing in the soil. Reproduction is often parthenogenetic (females reproduce without males).

Risks & Benefits

Potential risks include significant damage to garden and nursery plants, particularly the roots by larvae, which can lead to plant death. They are considered agricultural and horticultural pests. There are no direct benefits to humans, and their ecological role is primarily as herbivorous insects.
