Polyphaga saussurei ootheca

[Diabelskiii]

Hi, so my last Polyphaga saussurei died today. I decided to look through substrate so i knew i hadnt missed any oothecas and... i found some ( 7 ) .

How can I maximize the probability of them hatching?

I kept mine buried in the substrate in between the moist and dry sides of the enclosure, usually erring towards the drier half. Keep them warm and hope for the best, can take about 8 months maximum for them to hatch.
