Black Vine Weevil

Natural Habitat

Found in gardens, nurseries, and greenhouses; frequently associated with ornamental plants, deciduous trees, and broad-leaved evergreens.

Diet & Feeding

Adults feed on the leaves of over 100 different plant species (creating characteristic notches), while larvae feed underground on plant roots and stems.

Behavior Patterns

Adults are flightless, nocturnal, and reproduce through parthenogenesis (all individuals are female). They typically hide in soil or mulch during the day and emerge at night to feed.

Risks & Benefits

They are considered a major horticultural pest; larvae can kill plants by girdling the roots, while adults cause aesthetic foliage damage. They pose no direct risk to human health.
