In a remarkable contribution to the field of entomology, Md Jahir Rayhan and Sayema Jahan, a zoologist couple from Chattogram, have successfully identified a new genus and species of moth, naming it Paraxenoacria spinosa. This significant discovery showcases not only the couple’s dedication to research but also their passion for uncovering the mysteries of nature.

The Discovery Process

The couple’s journey in identifying Paraxenoacria spinosa began in April 2024 when they collected larvae from the University of Chittagong. Over six months, they reared the moths in their lab, meticulously studying their morphology and behavior. This involved observing the transition from larva to adult while taking notes on key characteristics such as feeding habits, cocoon construction with silk, and wing designs.

“From the larva stage to the adult stage, we examined the smallest of the morphological characteristics under the microscope,” said Rayhan. “Through these microscopic studies and comparisons with other species within the Paleopodidae family, we determined it is distinctly different from known species.”

A Unique Name with Significance

The name Paraxenoacria spinosa is rich in meaning. The term ‘Paraxeno’ is derived from Greek, meaning bizarre or peculiar, which is fitting as the moth features an excavation unique to its rear wings, setting it apart from others in the Acria genus. The species name ‘spinosa’ references the distinct spines found in the male genitalia, a feature that includes six to seven tall spines, marking its uniqueness among moths.

“Every organic being of the earth needs a scientific name—be it a plant, a microorganism, or an animal,” Rayhan explained, emphasizing the importance of a recognized nomenclature in scientific communication.

Why Moths Matter

The impact of moths extends beyond mere taxonomy; these insects play crucial roles in ecosystems. From contributing to the silk industry to serving as a protein source for numerous animals, moths are integral to both biodiversity and human life. Rayhan more pointedly noted that certain moth species are essential for pollinating crops like papaya, demonstrating their ecological significance.

“In the scientific world, we often use the proverb, ‘No Hawkmoth, no papaya,’ to illustrate the vital relationship between moths and plant reproduction,” he added.

The Wider Implications

With over 150,000 moth species documented worldwide, the discovery of Paraxenoacria spinosa adds to the rich tapestry of life identified across South Asia, including neighboring countries like India and other Southeast Asian nations. Its specimen is preserved at the University of Chittagong’s museum for future research opportunities, ensuring that contributions to scientific discovery do not end here.

Future Research and Contributions

Md Jahir Rayhan and Sayema Jahan, both graduates of the University of Chittagong, are committed to further research. Rayhan has recently returned from a research stint at the Florida Museum of Natural History, focusing on the evolution of moth silk and the molecular structure of pest moths. Meanwhile, Jahan is engaged in a project studying the endangered Sundarbans crow butterfly, further underscoring their dedication to conservation and entomological research.

“Our work ultimately contributes to a larger understanding of biodiversity and ecosystems, and we hope that our discoveries will inspire future researchers,” Rayhan remarked.

Engage with Science

As the scientific community celebrates this significant milestone, the work of Rayhan and Jahan serves as a reminder of the countless unknowns still waiting to be explored in nature.
