Solenopsis clarki

Stray workers or nests of Solenopsis clarki are often found when galleries in the nests of other ant species are excavated. Nests can also be found under rocks and pieces of wood or bark. (Heterick 2009)

Identification
Heterick (2009) - Widespread in the SWBP, WA and may extend much further north (what appears to be the same species also occurs in the Kimberley region). This species shows monophasic allometric differences between smaller minor workers and larger major workers. The two sub-castes possess a similar morphology but the major worker is larger and darker in colour with a broader head capsule.

Distribution based on Regional Taxon Lists
Australasian Region: Australia.
