The rare beetle Elater ferrugineus was sampled at 47 sites in the county of Östergötland, Sweden by meansof pheromone-baited traps to assess its value as an indicator species for hollow oak stands rich in raresaproxylic beetle species. In addition, Osmoderma eremita was also sampled with pheromone baits. Thesedata were then compared against species survey data collected at the same sites by pitfall and windowtraps. Both species co-occur with many Red Listed saproxylic beetles, with E. ferrugineus being a somewhatbetter indicator for the rarest species. The conservation value of a site (measured as Red List pointsor number of Red Listed species) increased with the number of specimens of E. ferrugineus and O. eremitacaught. Accuracy of sampling by means of pheromone trapping turned out to be radically different for thetwo model species. E. ferrugineus traps put out during July obtained full accuracy after only 6 days,whereas O. eremita traps needed to be out from early July to mid-August in order to obtain full accuracywith one trap per site. By using E. ferrugineus, or preferably both species, as indicator species, accuracywould increase and costs decrease for saproxylic biodiversity sampling, monitoring and identificationof hotspots.
