Two observations come from the iNaturalist platform (checked and confirmed by the authors) and four from authors' (UM, LB) observations. All the specimens collected by the authors were observed during the hottest hours of the day, all on different flowers: the specimen from Sessera Valley was observed on violet Knautia sp. or Scabiosa sp., the specimen in Oncino was observed on Hypericum sp., the specimen in Frabosa Sottana was on white Dipsacus sp. and the one in Nucetto was near Fragaria vesca. While for iNaturalist observation the specimen from Ormea was on Scabiosa sp. while the specimen from Armeno was on Carduus sp. or Cirsium sp.
