Stag beetle

Odontolabis wallastoni

A species of Odontolabis

The stag beetle is found mainly throughout Malaysia and Sumatra but can be found in other parts of Southeast Asia as well. As a member of Odontolabis, these beetles have a certain shine to their exoskeleton with a pronounced head and jaw. Interestingly, not all adults may look the same as these insects exhibit polymorphism.

Life Cycle of Stag beetle
Egg This phase begins with the stag beetle in an embryonic form enclosed in a protective casing. The shape is generally oval or spherical, and coloration can vary depending on the species. The egg size is tiny, and the primary function is to nurture the developing embryo.
Larva Upon hatching, the larval stag beetle often resembles a worm with a soft, elongated body, varying in color but usually paler than adults. These larvae are significantly larger than the egg, focus on feeding aggressively, and grow through a series of molts known as instars.
Pupal The stag beetle at the pupa stage is encased in a cocoon or puparium and undergoes significant transformation. It's immobile, with size generally similar to the final larval instar. The pupa exhibits muted colors, and during this period, the adult features are formed internally.
Adult Emerging from the pupa, the adult stag beetle’s development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction. Adult coloring is typically more vibrant and distinct.

How Can You Attract Stag beetle
Using sap or sweet fruits, both of which are attractive to stag beetle due to their diet that mainly consists of plant and fruit material, can be an efficient method to lure them for observation or capture.
Rectangle
Habitat Preferences of Stag beetle Through Different Life Stages
Eggs of stag beetle are often deposited in rotting wood or beneath the bark of dead trees, where the larvae also develop, feeding on the decaying organic matter. As the larvae mature, they remain in this woody habitat until pupation. To locate them, search through decaying logs in forested areas. Adults typically emerge from this substrate and can be found nearby on tree trunks or on the forest floor, often in close proximity to where they developed. To observe the adult stag beetle, look for them in areas with plentiful dead wood where they might be foraging or seeking mates.
Rectangle
When is the Best Time to Observe Stag beetle
The most suitable time to find adult stag beetle is during the evening or at night when they are most active. However, larval stages may be found throughout the day in their respective habitats.
Rectangle
What is the Best Weather to Observe Stag beetle
Warm, humid conditions are typically best to find stag beetle, as they prefer weather that supports a robust supply of their food sources and is suitable for their activity.

Golden stag beetle
Golden stag beetle

The golden stag beetle (Lamprima aurata) has a round, shiny body with mixtures of green, red, blue, and purple. The adults spend most of their time on the ground, but will fly to feed on flower nectar. The males are territorial, so they will guard an area on top of rotting logs. 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).

Hexarthrius parryi can reach a length of about 40–90 millimetres (1.6–3.5 in) in males, of about 40–54 millimetres (1.6–2.1 in) in females (length from the tip of the jaw to wing tip). Some individuals of the Sumatra subspecies (Hexarthrius parryi paradoxus) can reach a length of about 97 millimetres (3.8 in). Body is moderately elongate, not very shining, the basic color is black. Males have long jaws directed downward from the base, with bifurcated tips and a large yellow or bright orange patch occupying the posterior three-quarters of each elytron. The pronolum is short. The lateral angle of the prothorax is very sharp. The head is very broad, quite uneven and rugosely punctured. The mandibles are strongly curved, densely granular, with a sharp tooth directed upwards and another one directed downwards. The front tibia is finely serrated and the middle tibia has a strong lateral spine. The forewing shows a pair of brown spots.
