Notes

Larvae of the subgenus Isocladius are widespread in mountain lakes in the Alps ( Boggero 2018) and the Tatra Mountains ( Bitušík et al. 2006), but species composition is insufficiently known due to identification difficulties. C. (I.) speciosus belongs to the sylvestris group, members of which are mostly eurythermic and euryoecious. There is a considerable gap in the knowledge of the species' ecologies. Langton and Visser (2003) mention its occurrence in ponds, lakes and running waters.
