• Two new ant-fly species found in Delhi and Western Ghats.
• Metadon ghorpadei found in Delhi and Metadon reemeri in Siruvani Hills of Western ghats.
• These tiny flies were spotted by researchers H Sankararaman and S S Anooj.

Scientists have discovered two previously unknown ant fly species. The rare insects were found in Delhi and Western Ghats. One species emerged from Delhi’s Northern Ridge urban forest. The second species was located in Tamil Nadu’s Siruvani Hills. Both regions reveal unexpected biodiversity surviving within fragmented habitats.

What Did Scientists Discover?

Researchers have discovered two rare ant-fly species in India. These insects belong to the Microdontinae subfamily of hoverflies. They are unusual because their larvae develop inside ant nests. This behaviour makes them extremely difficult to spot in nature. The species were officially named Metadon ghorpadei and Metadon reemeri.

Where Are These Rare Ant-Fly Species Found?

Metadon ghorpadei was discovered in Delhi’s Northern Ridge Forest. The urban forest provides refuge for surprisingly rare species. Metadon reemeri was found in Siruvani Hills of Western Ghats. Western Ghats is a globally recognised biodiversity hotspot in India. Both locations highlight the importance of conserving even small habitats.

Why These Ant Flies Remained Hidden From Scientists?

These tiny flies were spotted by researchers H Sankararaman and S S Anooj, who used DNA tests to confirm that they are brand new to science. The larvae live secretly inside active ant colonies underground. They feed on ant brood, avoiding predators and researchers alike.

Such hidden lifestyle makes them rarely encountered in field studies. Few scientists explore urban forests for specialized hidden insect species. This secrecy explains why these species remained undiscovered for decades.

How Scientists Confirmed These Species Were New?

Researchers analysed body structures using detailed morphological examination techniques. Genetic tests compared DNA with previously known hoverfly species globally. Both species showed distinct features confirming they were entirely new. Scientific description and naming followed formal entomological protocols carefully. The discovery adds to India’s small known Microdontinae species list.

What This Discovery Tells about?

India hosts significant hidden insect biodiversity waiting to be discovered. Urban forests can shelter rare species despite human disturbances. Western Ghats continue to reveal unique species critical for ecosystems. Conservation is vital to protect small and fragile habitats. Each new species improves understanding of insect ecology and evolution.
