Life Cycle of Blue stag beetle
Egg The blue stag beetle begins life as an egg, often laid in close proximity to an ample food source. The egg is small, oval, and generally whitish or translucent, lacking distinguishable features specific to later stages.
Larva Upon hatching, the blue stag beetle in the larval stage is worm-like in appearance, exhibiting a voracious appetite aimed at rapid growth. Larvae are usually legged and segmented, moulting multiple times while increasing significantly in size.
Pupal After enough growth, the blue stag beetle enters the pupal stage, encasing itself in a protective cocoon or pupating within the soil. During this rest period, internal reorganization transforms the blue stag beetle in preparation for adulthood.
Adult Emerging from the pupa, the adult blue 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.

How Can You Attract Blue stag beetle
For attracting blue stag beetle, rotting wood and fermenting fruit can be used as bait in traps, since these are natural attractants for many Lucanidae species.
Rectangle
Habitat Preferences of Blue stag beetle Through Different Life Stages
The larvae of blue stag beetle typically reside in rotting wood, especially preferring hardwood stumps and logs for their high nutritional content required for growth. Searching for them involves examining decomposed woody areas, specifically within forested regions. Adults of blue stag beetle, however, are commonly found in areas with abundant undergrowth and leaf litter, often in the vicinity of their larval food sources, to facilitate mating and egg-laying. Locating adults would involve sifting through leaf debris in damp forested environments, which provide the necessary humidity for their survival.
Rectangle
When is the Best Time to Observe Blue stag beetle
The most suitable time to find adult blue stag beetle is during the nighttime when they are most active. However, to find larvae or other immature stages, the time may not be as specific and would require searching their habitats.
Rectangle
What is the Best Weather to Observe Blue stag beetle
Mild, humid weather is preferable for finding blue stag beetle since these conditions are conducive to the activity of many beetle species. Dry or extreme weather conditions may cause the blue stag beetle to be less active or to take shelter.
Rectangle
How and Where Can You Find Blue stag beetle at Different Life Stages
Larva Blue stag beetle larvae are typically found in decomposing wood or beneath the bark of rotting logs. Searching in these areas, particularly in the forests or woodlands where they thrive, can lead to successful findings.
Pupal Blue stag beetle pupae are usually immobile and can be found inside the wood where the larval stage was feeding. Cutting into rotten logs or investigating the interior of decomposing tree stumps may reveal blue stag beetle pupae.
Adult Blue stag beetle adults are easiest to find at night by using light traps or searching around sources of light where they may be attracted. During the day, they can sometimes be found on or under the bark of trees, in leaf litter, or near fermenting fruit.

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

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).
