Habitat Preferences of Rainbow stag beetle Through Different Life Stages
To find the larvae of rainbow stag beetle, one should search in rotting wood, especially from eucalyptus trees, as they require decaying organic material to thrive. These larvae prefer the moist microhabitat inside the wood, which provides both shelter and food. The adults, however, are commonly found in the forest canopy, where they fly in search of mates and suitable sites to lay eggs. To observe adult rainbow stag beetle, one might have to look around flowering trees—their food source—during nighttime when they are most active. To maximize chances of finding rainbow stag beetle, one should focus on the tropical rainforests of North Queensland in Australia, where these distinctive locations align with their life cycle stages.

This is because the larvae live in the soil below.

Golden Stag Beetle
Golden Stag Beetle

Odontolabis cuvera can reach a length (mandibles included) of about 43–90 millimetres (1.7–3.5 in) in male, of about 41–51 millimetres (1.6–2.0 in) in females. Moreover, males have a conspicuosly elongated and large pair of mandibles. The basic color of the body is black. Elytra have broad orange margins on the outer edge. The female closely resembles the male in coloration but it lacks long mandibles. The remarkably disparity between male and females (sexual dimorphism) evolved through sexual selection for securing mating females. The males have also three morphological forms with variations in the size of their mandibles. These three alternative phenotypes (male trimorphism) in the types of male weapons are considered conditional reproductive strategies. In the subspecies Odontolabis cuvera sinensis elytra are almost completely black, with a small orange border. These beetles can reach a length of about 80 millimetres (3.1 in).
