I’m still active. I down sized my collection, but I still got some cool stuff...
Just curious, what exactly is your personal rearing methodology for these? How do you keep the larvae, what are the survival rates typically, and how do you keep the pupae?
Humidity levels and temperatures, especially for the pupae would be much appreciated.
In my experience, that's... really short for this species.
In general, Tenebrionid pupal cells only collapse if the substrate isn't stable enough, or isn't humid enough... And honestly most species can be removed from their pupal cells in their pre-pupal state, placed on a compressed and smoothed out later of humid substrate, and then pupate and eclose just fine... Failure rates can be a bit higher that way, but not by much in my experience.
True true, still they may not actually be too difficult to breed, there are just very few serious Tenebrionid breeders out there, consider how few species are reared from larva to adult regularly in the hobby in any numbers, despite many easy to breed desert species being sold regularly as pets in the US... Even overseas, the interest in Tenebs is vastly overshadowed by interest in scarabs, and I rarely see people keeping this particular species. @Elytra and Antenna got offspring from his adults easily, way back when he kept them, unfortunately he lost his entire colony due to overwatering them.
I've bred several North American Pimellinae spp., so I'm familiar with the softer Tenebrionid larvae, which are the norm for that group, usually doesn't affect the husbandry that much, and oddly, some of them have proven even more dry hardy than some of the thicker shelled Eleodes spp, (though many of the Pimellinae have proven quite cannibalistic, if not outright predatory).
I'm actually kinda curious about this part. Googling didn't produce much info.
Thanks a lot!
