The eye is smallish to moderate in size in all subcastes.

. Cambrai (SA) foragers were collected in dunes, while other samples have been taken near rivers, from clay pans and from red sand. At Hilarys, WA, the principal author has collected the blackish south-western form of this species in white beach sand at a car park about 150 m from the ocean. This form has a small eye. Black workers with similar features (held in ANIC) have been recorded from the Stirling RA, WA. The black form with the small eyes has not been successfully sequenced. Despite its ubiquity, there are no data on the habits of this species (which, in any case, would not be identifiable in ecological papers) apart from the terse 'ground
