Introduction:

Researchers identified Palpares contrarius on the Madras Christian College (MCC) campus, a new species of antlion in Tamil Nadu, which marks addition to the region’s biodiversity.

Identification Features

Palpares contrarius resembles a dragonfly, which has distinct antennae and a unique fluttering flight. Antennal structure helps differentiate it from similar insects. Adults are elusive and primarily nocturnal.

Life Cycle and Behaviour

Antlion larvae create sand pits to capture prey. They primarily feed on ants. The larval stage can last over a year. Duration depends on environmental factors and food availability. Adults have a short lifespan and are seldom seen during the day.

Habitat and Distribution

Antlions are prevalent in several countries. They are found in Africa, Myanmar, Thailand, and Sri Lanka. In India, they inhabit states like Odisha, Maharashtra, Karnataka, Mizoram, Uttarakhand, and Madhya Pradesh. The discovery of this species in Tamil Nadu is unprecedented.

Research and Publication

Anita Pearline Esther, an entomologist at MCC, documented this finding. The research was published in the Journal of Threatened Taxa. The specimen has been preserved at the Zoological Survey of India in Chennai.

C Joyce Priyakumari leads the zoology department at MCC. She expressed enthusiasm about the campus’s insect diversity. Many species remain unstudied. Principal Paul Wilson announced plans for comprehensive fauna research on the 320-acre campus. The area is home to various wildlife, including spotted deer.
