This orchid shows great variety of colour, hence both its common and scientific names. It is found in an area bounded by Bunbury, Hyden, Jerramungup and Mt Barker. It is most common in winter wet flats under Wandoo trees. Apart from its colour variability, there is little difference between it and the Common Spider Orchid (Caladenia vulgata) I consider the Joseph Spider Orchid to be the 'normal' wispy spider orchid in its range. It is most common between Frankland and the Stirling Range and also out towards Jerramungup.

The Common Spider Orchid, as its name suggests is found throughout the entire south west. It can be considered the 'normal' wispy spider orchid in most areas. I'm not sure how to positively identify it as it visually resembles many of the subspecies and its distribution suggests that it can be found along with many of the other species of wispy spider orchid.
