Advertisement I have had a lot of people ask me about getting blue death feigning beetles to adulthood in captivity. I also see a number of conflicting posts here in the forums about the subject. For anybody interested, it IS possible and takes less than a year. This video shows what you can achieve with the right setup. PM me for details if you want to try to rear them yourself. If you are clever, you can figure out from this video the substrate and temperature used to induce maturing larvae to pupate and eclose. Consult my other posts for food etc. used. It takes between 5-12 months to get from egg to adult.
