A lot of desert darklings do have their elytra fused, and don't even have flying wings underneath, Tenebrio molitor and a lot of the other grain pests on the other hand don't have fused elytra and can in fact fly, though I found the adults in my T.molitor culture were usually reluctant to unless conditions were bad.

Larvae are predatory and will feed on dog food and live invertebrates. Adults feed on fruits. Like @Lucanus said, those are probably Ignelater havenensis, nice find, been wanting to try my hand at culturing that species... Should be identical in care to Pyrophorus, so far the two Deilelater spp. I got from @Lucanus have been at least.

Almost two centimeters long, a fairly small Eleodes species. Found in southwest Idaho.

Thanks!

Good to know. And yeah that sounds about right, Asbolus like things sandier, whereas ironclads supposedly spend their larval stages within rotten wood, or at least in decaying organic matter of some sort, (as opposed to the inorganic substrates Asbolus typically dig through).

Congratulations, this is awesome news, no fungus needed for oviposition! Just based on how Zopheridae larvae look, (very similar to Cnodalonini Teneb larvae), I'd highly recommend isolating your larvae, there may be a good chance they're cannibalistic like Cnodalonini larvae are. For protein I'd also try offering buried dog kibble pieces or some alternative, keep them humid, maybe offer some rotten wood, and just hope for the best really, you're in uncharted territory here. Also, for the rain simulation for adults, are you just misting heavily at the beginning of each month, and

Yeah that sounds good, with sand and the potting soil/coco fiber making up the bulk of the substrate.

Sand and coconut fiber would suffice, rotten wood would be a luxury item, I never use it with desert Tenebs personally, as it's not a food source they come across regularly in the wild. Leaf litter would be good though.

The ones I see here are Eleodes armata, Coelocnemis do not have femoral spines, and E.armata is distinguished from other Eleodes by having spines on all three pairs of femora, not just the front pair. As for the eggs, bury them in humid substrate, and hope for the best.

Coelocnemis dilaticollis (formerly known as C.californica) are more difficult to breed than your average desert darkling beetle, they require a substrate of rotten wood to oviposit in and for the larvae to develop in, but the larvae are also very cannibalistic and need to be separated as soon as they hatch. Only a few people have reared Coelocnemis to adulthood, it's not an easy genus to work with.

They're honestly more concerned about diseases that can affect plants than humans.

Welcome to the forum!

Very smol. 😂
