EGG COLLECTION

Observe the nappy liner across the top of the moth bucket each day after emergence and check for eggs.

Once the moths start to lay eggs on the nappy liner, it is best to collect the eggs each day so they don’t hatch in the bucket.  To avoid moths escaping during the egg collection process follow these steps:

  • Remove the bucket lid and place a new nappy liner over the current nappy liner. 
  • Gently sit the bucket lid on top of the nappy liners on the rim of the bucket.
  • Hold the new nappy liner at one end and slowly pull the old nappy liner in the opposite direction.  Make sure the new nappy liner continues to cover the bucket opening or your moths will fly out and escape. 
  • Fold the nappy liner with eggs on it and place it in the provided zip lock bag. 
  • Firmly secure the bucket lid down.
  • Repeat the process each day until moths stop laying eggs. 
  • Several nappy liners can be kept in the same zip lock bag.

Once the moths cease laying eggs, they will die naturally over several days in the bucket. 

If you wish to repeat the lifecycle you can allow the eggs to hatch in the zip lock bag. Wash and dry the rearing pots and lids provided in the kit.  The larvae can be raised on a range of food sources such as plants from the vegetable garden, seedlings from the nursery or students may wish to bring in some plant material from the crops/plants grown at home on the farm or in the garden.  Use the paintbrush to pick up neonates and transfer them onto the plant material in the clean rearing cups.  Place the lid on top and replenish the food source as required.  

If you do not want to repeat the lifecycle you can place the moth bucket with the moths and the zip lock bags with the eggs in it in a freezer overnight.  You may wish to examine the frozen specimens under a microscope.  Discard the insects in the general waste when you have finished.
