Recently, Vincent spent two weeks in the huge Lepidoptera collections of the Bavarian State Collection of Zoology in Munich where all Geometridae collected during our Mount Cameroon project are stored. Thanks to our long-term collaboration with Dr. Axel Hausmann, all geometrid specimens are now set and ready for identification. Vincent helped with processing of this material, especially with identification to morpho-species, but some poorly known genera still hide a high number of cryptic diversity. Therefore, under Axel’s supervision, Vincent dissected several hundreds of specimens to improve their identification and sorting. We are glad that also this huge dataset is approaching its finalistation.
