Here's a reptarium with a female calling to a mate. I set the cage out into the yard - helps the pheromones catch the wind.
Most times the female will stay put so I am able to unzip a flap. This time several males showed up within minutes so I unzipped a flap and let several get in. It's amazing how they flit around the cage trying to find an opening :o)
Once a couple hooked up I removed the other males and left the mating pair alone. For this species, Rothschild Forbes Silkmoth, the pair mates for about 24 hours.
