Morphology of the last instar larvae of Prionyx thomae (Fabricius, 1775) and P. fervens (Linnaeus, 1758).

The article discusses the study on Prionyx thomae (Fabricus, 1775) and Prionyx fervens (Linnaeus, 1758), describing the morphology of their last instar larvae, obtained from eggs collected in natural nests during behavioural studies. The coronal line of the head capsule was well developed with no cephalic rugosity while its antennal orbits were unpigmented. The labrum's maximum width is 470 µm with approximately 60 punctures of four to six µm in diameter.
