Coleoptera, largely known as beetles, is the largest member amongst all insects in the world. There are about 350,000 described species within the family in the world which represents more than 40% of all insects and nearly 30% of all animal species. However, the number of the described insects is still thought to be highly underestimated.The photographed Neolucanus sp. was found at high elevation in Hong Kong. I've seen a number of this species appearing mainly around late May to Mid July these two years.
