In 1878 he travelled to Croatia and Slavonia with Baron von Hopffgarten and Ritter to collect insects. He received an honorary doctorate from the University of Bonn in 1875. He collected extensively across insect group in these travels and nearly 200 species from across the insect orders have been named after him. He described at least 500 new taxa on his own.
