Observations on ecdysis and head capsule measurements show that the larvae of Solenopsis invicta Buren undergo four instars. The mandible, labrum, labium, maxillary palp and galea are good characters for differentiating the instars but not the castes. Dyar's (1890) principle is valid for separating the instars of Solenopsis invicta.
