Male-Male Competition in Feisthamelii Stag Beetles

Within many species, members of the same sex (usually males) compete against each other for reproductive access to members of the opposite sex. Natural selection often favours the adaption of larger size, strength and weaponry in the competing sex, as individuals must outcompete rivals in direct encounters. The enlarged mandibles of male Stag Beetles are an excellent example of how selection pressures can result in incredibly ornate and highly specialised features.

This pair of Stag Beetles (Sphaenognathus feisthamelii) has been hand set by our expert entomologists in our studio and elegantly mounted in a museum quality deep box frame.

The picture shown is an example of the quality that you can expect to receive. Please be aware that, as these are natural products, they are subject to some variation. While no two insects are exactly alike, each of the specimens in our collection fall within the morphological perimeters for their species.

All of the insects in our collection are responsibly and ethically sourced through sustainable insect farming and commercial breeding. 

This approach helps native communities generate a sustainable and equitable income, while providing an economic incentive to protect endangered habitats rather than environmentally destructive practices such as deforestation for logging and agriculture.
