So I was visited by a gentleman early this morning wanting to sell me a beetle. I'm thinking it is a small female Augosoma centaurus (though it's about half the size of the one I already have in my collection... so I'm not sure). Anyways, he wanted to sell it to me for $5 US... utterly ridiculous. I ended up giving him 500Fc (about $0.50 US) partly so that he'd stop bothering me and partly because I didn't want to discourage him from showing up with other interesting insects he might find... it was still too much for that particular specimen. The upshot to all that though, was that one of the street boys I work with witnessed our exchange. He speaks about as much french as I speak Swahili, so I doubt he understood what was going on... but what he did see was that I kept the beetle. This afternoon he came to me carrying another specimen (slightly larger and in better condition). Awesome! It's fun hunting butterflies with them, maybe now they'll also be on the look out for beetles. So, after some confusing communication, he finally understood that I wanted to know where he had found it. He went, grabbed a shovel, and led me to a nearby mound of dirt. We spent about 30 minutes digging through the dirt, finding 2 more adult females, 2 larvae, and 4 pupae. So, finally, my question: What do I do with the larvae and pupae? I've currently got them in a large jar full of dirt. Thanks! Tom (I can post pictures if they'd be helpful.)

Just rear the larvae in the substrate you found them in until they pupate and wait for them to hatch. You have to renew the substrate when there are too many feces (pills) in it. Put the pupae in the cardbox rolls of toilet paper and put them on the substrate as well. Always keep the moisture at level as it was where you found the larvae and pupae.

So, since the larvae were found buried in the dirt, what were they likely eating?
Also, are there signs to look for that would indicate they are ready to pupate? Or that indicate they are ready to eclose?
How long should I expect them to stay in pupal form?
Thanks for any help anyone can provide! Tom

If it really is Augosoma centaurus or another Dynastid species they feed on decayed wood and humus. The larvae get kind of yellowisch when they are getting nearer to their pupation but it still can take some time then. You should give them enough space because the cocoons can get quite big. Best is to keep every larva seperately. The pupae get darker legs and eyes when ready to eclose.
