Palparescontrarius is a species of antlion that was recently spotted for the first time in Tamil Nadu, on the Madras Christian College (MCC) campus. It is notable for being a large-sized adult antlion that resembles a dragonfly but has distinct characteristics that separate it from dragonflies, such as its clubbed antennae and fluttering flight.

Key Features of Palparescontrarius:

• Appearance:
  • The adult Palparescontrarius is large and resembles a dragonfly in its general body structure.
  • It has lacy wings, long clubbed antennae, and a slender, grayish body.
  • Its wings are typically clear, although some species of antlions have spots on their wings.
• Flight and Behavior:
  • Unlike dragonflies, Palparescontrarius has a distinct fluttering flight.
  • It is a weak flier and can often be spotted at night near illuminated spots.
• Habitat and Lifestyle:
  • Like other antlions, Palparescontrarius is found in dry, sandy regions and is mostly active at night.
  • The larvae of this species are particularly known for their predatory behavior, as they trap ants and other small insects in cone-shaped pits they dig into the sand.
• Ecological Importance:
  • Antlions, including Palparescontrarius, are harmless to humans and beneficial to the environment because they feed on ants and other insects, thus helping to control pest populations.
