The butterfly is locally uncommon in montane dense bamboo forests at moderate elevations (Alt. 800 - 1100m). S. godfreyi is found sympatrically in many habitats, but is much rarer than S.godfreyi.
It was recently found in the Phetchaburi area, but only photographed in the field. It is likely to belong to this taxon, but confirmation by specimens is needed.
The characteristics of this taxon resemble those of mathilda, not louisa, therefore I tentatively treat it as a subspecies of mathilda. However, I suspect that this taxon could be a distinct species based on its distribution. Further taxonomic and distributional studies, including DNA analysis, are needed.
