Notes: For illustrations and further details on this species, see Shear (2007). Idagona westcotti will likely be found in many other lava tubes in central Idaho. The species may disperse through the porous lava to colonize tubes. While pale in color and with somewhat reduced numbers of ocelli, populations are not conspicuously adapted for subterranean life.
