Can anyone explain what the difference is between Blue bottle and Housefly hatching? My houseflies barely hatch at all.

Help Support Mantidforum:
If you are asking if there is any difference in setting the pupae out to emerge, there is no difference.
With both species of pupae you simply take out as many pupae that you need and place them into a container with a lid, or a mantid habitat. Place them on the surface in a warm dry spot in the container. The pupae emerge in 2 to 3 days (sometimes longer depending on the temperature), there is nothing special for either species, just a warm dry spot to emerge.
The pupae are kept in a refrigerator to prolong their pupae state until needed. The pupae will last about 2 weeks in the fridge then their emerging rate takes a nose dive, after about 3 weeks 25-50% will emerge, and by the 4th week usually none will emerge.
Any pupae that are dark in color, nearly black, are dead pupae and should be discarded. If you purchased your pupae recently then you likely got a old batch (happens sometimes); otherwise, you had the pupae about 3 weeks already or they are getting wet or too cold to emerge properly (room temps of 70s F is fine).
Thanks for the info Cosby, there is also a good feeder care sheet on my site for flies.
