The Black Flower Beetle is a common beetle often found visiting flowers where it feeds on pollen and nectar. Many species fall within the scarab beetle family Scarabaeidae, particularly within the flower beetle group known as cetoniines. These beetles are generally harmless and are commonly seen in gardens and natural landscapes.
Identification
Black flower beetles typically have shiny black or dark metallic bodies and range from 1/2 inch to over 1 inch in length depending on species. Their bodies are oval and slightly flattened, with hard wing covers protecting the flight wings beneath. Like other beetles, they possess chewing mouthparts used for feeding on plant materials.
Distribution and Habitat
These beetles are widely distributed across North America and are frequently found in gardens, meadows, orchards, and forest edges where flowering plants are abundant.
Life Cycle and Behavior
The life cycle consists of egg, larva, pupa, and adult stages. Larvae usually develop in soil, compost, or decaying organic material. Adults emerge during warm seasons and are frequently observed on blossoms.
Pest Status
Most black flower beetles are not considered pests and are often beneficial pollinators. However, some species may feed on flower petals or fruit when populations are large.
Prevention
- Maintain healthy flowering plants.
- Remove overripe fruit that may attract beetles.
- Encourage natural predators.
Control
Control is rarely necessary. If beetles become abundant, manual removal or traps may help reduce numbers.
