Stag beetle
Likely Lucanus species (exact species cannot be confirmed from the image)
- Order & Family
- Coleoptera; Lucanidae
- Size
- Typically 20–60 mm long, depending on species and sex; males are usually larger and have prominent mandibles.
Natural Habitat
Woodlands, forest edges, parks, and gardens, especially where dead or decaying hardwood is present. Adults may enter buildings when attracted to light.
Diet & Feeding
Larvae feed on decaying wood and associated fungi. Adults mainly consume tree sap, nectar, or fruit juices and often feed little.
Behavior Patterns
Males use their enlarged mandibles in courtship and contests; females have smaller jaws. Larvae develop in rotting wood for several years before pupating, while adults are often active at dusk or night.
Risks & Benefits
Harmless to people and generally do not damage sound timber or living plants. Larvae help decompose wood and recycle nutrients, making them beneficial woodland organisms.
