The production of berried females in controlled condition is essential for that knowledge on mating behaviour is very much needed. Hence in the present study mating behaviour of C. feriata was studied. For convenient, the mating behaviour of C. feriata is divided into five phases viz., Pre-moult Guarding (PMG), Moulting (M), Precopulatory guarding (PCG), Mating or Copulation (C) and Post-copulatory Guarding (POCG). Premoult guarding is last for 92.0 hrs. Moulting last for 4.0 hrs. The Pre-copulatory guarding lasted 3.6 hrs. The copulation lasted 7.28 hrs and Post-copulatory guarding lasted 12.12 hrs. The total mating sequence lasts for 119.00 hrs.The spawning of the female took 17.62 days after copulation.
