Hey guys, I'm not sure what I'm doing wrong, I really don't think it should be this hard but I'm having trouble. I've bought blue bottle flies larve from 2 different reputable insect suppliers so I really don't think it's the source.(I could be wrong) I stored them in the fridge as soon as they arrived, about 3 days later I took 10 or so out, stored them dry at room temp (about 72 degrees) and waited for them to hatch. I know if it's cooler they take longer to hatch but it's been about 3 days and no hatching. Then I took another few and stored them in one of my enclosures (about 82 degrees) it's only been about 24 hrs on the higher temp ones but I thought they hatched out sooner being at a higher temp. Any thoughts would be helpful.

I would take out (20 or so) and add to those you already have out and give them a couple more days. If they do hatch and you have more than you need you can always put them back in the fridge and they'll live for a while. On a few occasions I've had pupae take up to 5 days to hatch out. If none hatch out in the next few days, I'd contact the seller, however it's unusual to get a bad batch from 2 different sources. 🤞

 
Maggot casters can up to 2 weeks to hatch. The temperatures you have them at though you should see flies sooner than that. I would still say around a week or more before they hatch. I find they hatch quicker when their put in soil or substrate. 

 
Usually the fresher pupae you get the longer to hatch, In the summer under warm conditons it take a maggot 8 days to hatch. It feeds

until full or the age to pupae, once it pupae starts it takes 8 days to turn into a fly, did Isay that right?
