Based on the publication "Development and constancy of the markings in Neurergus kaiseri K. P. SchmidT, 1952" (Kalina & Schultschik, 2014), the photographic material collected at that time was now used to examine the program IBEIS with regard to its results in individual recognition based on the different marking patterns of the animals.
The idea for the first publication was conceived as Neuergus kaiseri was added to Appendix 1 of CITES in 2010. So Individual recognition of each specimen was necessary and should preferably be performed with non-invasive methods.

In the underlying study, photographs of 36 animals (development from larva to adult) were taken at regular intervals over the course of a year. Their recognizability in successive photographs is now being tested by the probability of correct individual assignment using the image recognition software IBEIS.
