The European stag beetle (Lucanus cervus) fires one’s imagination. It is named after the jaws of the male beetle, that look like the antlers of a stag. It is also one of the biggest beetles in Europe, the males can become a stunning 9 cm long! The European stag beetle requires a specific habitat, mainly due to the ecology of the larvae, which feed on rotten wood below the ground.

This fascinating species is threatened. In order to protect the European stag beetle, we want to know more about the population size, distribution and trends. And that’s where citizen scientists come in: we need your help! Only with the help of volunteers we can follow up the population and habitat at individual sites. For more information, take a look at the volunteer page.

Who can join? 

  • Location: All within the range of the European stag beetle
  • Project type: Fieldwork
  • Cost: Voluntarily, free
  • Grade level: All ages, no expertise needed
  • Time commitment: Less than 1 hour per week in June and July
  • How to join: Register as a volunteer via this website


The European Stag Beetle Monitoring Network aims to:

  • start up an international network of population monitoring transects that follows up the European stag beetle
  • enlarge and endure the monitoring network to cover the full range of the species
  • assess the red list status (extinction risk assessment) based on population monitoring data
  • communicate the findings of the monitoring and raise awareness about the threats this umbrella species is facing
  • this network will allow many other studies concerning its ecology and conservation techniques.
