Icaricia saepiolus ssp. insulanus (Blackmore)

Vancouver Island Blue (Icaricia saepiolus ssp. insulanus)

The Vancouver Island Blue was described in 1920; it was restricted to Vancouver Island, British Columbia, Canada.

This taxon hasn’t been seen since 1979 and is feared to be extinct.

Xanthippus aquilonius Otte

Northwind Band-winged Grasshopper (Xanthippus aquilonius)

This species was described in 1984 based on specimens from Kettle- and Okanagan Valleys in British Columbia, Canada.

The species appears to be lost or even extinct, on the other hand it might not be valid after all but might turn out to be identical with the Red-shanked Grasshopper (Xanthippus corallipes (Haldeman)) (see photo).

Coregonus sp. 2 ‘Dragon Lake’

Dragon Lake Whitefish (Coregonus sp. 2)  

The Dragon Lake is a 2,25 km² resp. 225 ha large lake in British Columbia, it is a popular destination for anglers and well known for its large rainbow trouts (Oncorhynchus mykiss (Walbaum)) – however, that wasn’t always so.  


The lake was once the home for two sympatric whitefish species – both species have never been described, and both species fell victim to a so called ‘lake rehabilitation’ in the year 1956.  

The term ‘rehabilitaion’ disguises the pervert idea, to reshape a lake appropriate for so called game fishes by using insecticides like rotenone and toxaphene, both of which are simply deadly for fishes, to exterminate all living things, so that, later, when the poisons have vanished from the water of the now dead lake, the desired game fishes can be introduced – in the case of the Dragon Lake rainbow trouts.  


The Dragon Lake Whitefish was similar to the Lake Whitefish (Coregonus clupaeformis (Mitchill)), but differed from this species in the number of its gill rakers.
