If you do wait for it to split open
though it doesn't "toss" the seeds too far, some of them DO drop down to the soil. I found 8 seeds by looking very very closely, a year after my generation died, sitting on the soil. When the pod is ready, you could take scissors and cut it off, then open it over a clean white paper. You should probably wait until the stalk is starting to die.
Or, if you were really into it you could even take some seran wrap and make a little bubble around the pod, and wait as long as you want.
For temperatures, like dewy said 80 is good, but remember---they can take much, much hotter. I think my last few seedlings had 100 degrees to sprout. Little byblis liniflora are very tough. Humidity is a must to sprout them, but once they sprout they can take lower.
