Attempting to keep and breed Phellopsis porcata

[maximsm98]

I'm trying my hand at keeping Phellopsis porcata, the western ironclad beetle. As far as I have found, very little is known about their mating and breeding habits. I collected them in August (2 individuals) around Bellingham, WA. I've given them a variety of fungi to chew on and they eat well; I've mostly seen them chewing on polypores, but also on dried wood ear that I bought for human consumption and possibly on rotted wood too. On Sep 8th I put a large fallen polypore into their enclosure and the next morning I caught them mating next to it. The photo I got is pretty bad because I didn't want to scare them. I am assuming therefore that this is a different-sex pair, and the female is the darker brown individual. The polypore that seemingly triggered the mating grew a bit of mold recently but the growth has stopped; this one was found already detached from whatever it was growing on so it's possible they won't want to lay eggs in it (assuming they do it directly into/onto the fruting body). Please comment if you have any advice or ideas! Will update if I find any evidence of egg-laying. Pics below of the mating and of them hanging out sweetly.
