Notes

Similar to I. lautatorius . Although this species is very common in many European countries, especially in summer months on umbellifers, hibernation records are relatively rare and mostly recent. This may suggest either facultative hibernation or a strict preference for using certain hibernacula (or a combination of both), in this case apparently grass tussocks and stones. This is reflected in the country records, with only one record for both France and Germany (little tradition in tussocking), but quite a lot of records for the United Kingdom (good tradition of tussocking). Very recently in 2024, two specimens were discovered under bark for the first time in Belgium and Germany.
