The Standard 500ml Fruit Fly Culture from Mantis House is the ideal choice for maintaining a healthy and thriving diet for your praying mantis. All you have to do is place it somewhere at room temperature 20 to 22 Celsius. Watch and wait for the flies to pupate and emerge as adults. The time period for the culture to develop, pupate and adults to emerge may vary depend upon the developmental stage of the culture and the ambient temperature. D. hydei take about 3 weeks.
 
Wait to harvest until you see maggots.
This is a vital part of ensuring your culture provides you with lots of flies. Fresh cultures can take a few weeks to mature; if the adults provided aren’t given the chance to breed, the culture will crash and you will need to start over.
 
Too much heat will cause a culture to crash.
If your culture looks too dry add a drop of water.
