🪰 Greenbottle Caster Hatching Guide
 

Storing Your Casters

• When your casters arrive, place them into a breathable container with good ventilation.

• Transfer the container to the refrigerator to slow down fly development.
   

Hatching Your Flies

• When ready, remove slightly more casters than you need and place them into another breathable container.

• Keep this container in a warm, dry place.

• Casters will usually hatch in 5–10 days (they will darken to almost black before emerging).

• Many casters I supply hatch much faster — often within 24–48 hours.
   

Continuous Supply

• For a steady stream of flies, stagger when you remove casters from the fridge and repeat the process.

• If you have more flies than needed, simply place them back into the fridge to slow their metabolism and extend their lifespan.
   

Caring for Live Flies

• On arrival, live flies should be refrigerated to prolong their lifespan.

• If feeding immediately, even better.

• Offer sugar water, diluted honey on kitchen roll, fruit, or a jelly pot as a food source.
   

Important Notes

• In warm summer months, a small percentage of flies may perish during shipping.

• I always include extra flies to account for any losses.
