Abstract
Larval abnormalities in insects can be a sign of environmental changes and stress. Therefore, these abnormalities could serve as bioindicators of environmental shifts. This study examined larvae of Onychogomphus forcipatus albotibialis Schmidt, 1954, Sympetrum sanguineum (Müller, 1764), and Platycnemis pennipes (Pallas, 1771) species. The antennae of O. forcipatus albotibialis larvae displayed various deformities. Unexpected changes in the setae series in the mentum region of the labia of S. sanguineum, a diagnostic characteristic, were also observed. Additionally, P. pennipes had a deficiency in the labial palp setae. By understanding how different factors can affect larval development and how these changes can manifest in different parts of the body, the findings of the present study emphasize the importance of identifying and diagnosing these species through the images of the anomalies observed.
