ABSTRACT
Phylogenetic reconstruction is a fundamental aspect of understanding the evolutionary relationships and diversification patterns within insect taxa. This study focuses on the construction of a comprehensive cladogram for Hymenoptera and Odonata insects, two diverse and ecologically significant orders. A data matrix approach was utilized, incorporating a wide range of morphological characters from representative species within these orders. The data matrix comprised of various anatomical features such as Eye, Antennae, Wings, Abdominal Segment, and Abdominal length. The constructed cladogram provided compelling evidence supporting the monophyly of both Hymenoptera and Odonata Interestingly, the cladogram also indicated instances of convergent evolution and potential homoplastic traits within Hymenoptera and Odonata, suggesting adaptations to similar ecological niches across distantly related taxa. The findings of this study contribute significantly to our understanding of the evolutionary relationships and diversification patterns within Hymenoptera and Odonata insects. The constructed cladogram serves as a valuable framework for further investigations into trait evolution, ecological interactions, and biogeographic patterns within these orders. In conclusion, the data matrix approach, coupled with phylogenetic analyses, provides a robust foundation for elucidating the evolutionary history and interrelationships of Hymenoptera and Odonata insects. This research contributes to the broader field of insect phylogenetics and offers insights into the remarkable diversity and adaptive radiation within these ecologically important insect orders.
