A few days ago, two of the larger larvae pupated, and several more are pre-pupal! Here are some pictures of the pupae:
Even as pupae these things are hefty, I'm hoping they'll mature to be the same size as most of the wild adults I saw! 😁🤞 But first, they must eclose successfully, which I'm hoping they will, in the past I had theorized that the low survival rates some had experienced with this species were due to pupae being picky about their humidity levels, like with E.armata and spinipes, but now I'm thinking the low survival rates people experienced in the past were due to keeping large larvae together. Which might mean that the pupae of this species are actually pretty hardy, we'll see.
Anyways, that's gonna do it for this brief update, thanks for reading everyone, I hope you enjoyed, stay safe, and I'll see you all in the next post! 😉
What temps & humidity do you keep the pupae at? Out of every 10 larvae, how many make it to adulthood?
ReplyDeleteE.obscura in particular is a very difficult species to pupate successfully. I've tried a variety of humidity levels and temperatures, and out of every 10 larvae I maybe had 1 make it to maturity. I've actually never reared this particular subspecies of obscura to adulthood. It seems they need a temperature drop for best results, maybe low 70s to high 60s. A more inorganic mix seems preferable for the larvae to make their pupal cells in, and they need some humidity, but not very moist conditions (they are prone to rotting). Overall not at all an easy species to rear, I'd recommend E.spinipes macrura or E.suturalis as far easier, large Eleodes to keep and breed.
