  1. That's a beautiful beetle! Thanks for sharing the pics!
  2. I'm surprised too! I wasn't sure what to expect, but I wanted to try to give it a shot since their tree fell over, poor things. If this larva makes it all the way to a beetle, that will be amazing. It's a big one, so it may just be developed enough that it can make it the rest of the way without its ideal food, I don't know. Cross your fingers for me!
  3. In case anyone is interested in an update -- the second, smaller larva was dead a day or two after I posted when I checked the container. It may have been stressed out after being removed from its tree (they came from someone who found them after a tree uprooted and didn't know what to do with them). The big one seems to still be going strong, and it has been eating the apple and potato. I haven't checked on how much it has eaten because I don't want to bother it too much, but it has been yanking the potato all over the place and it's looking rather chewed. The apple also looks like it's b
  4. Does anyone have any experience or information on raising Derobrachus germinatus / palo verde beetle larvae? I have two and have been unable to find much information on caring for the grubs. I've found anecdotal reports that they can be raised on apple slices, but mine don't seem to show much interest in apple. (Or carrot, for that matter.) I will be offering potato and squash as well, as everything I have been able to find indicates that they eat tree roots for the starches contained in them. Currently they are in substrate of mostly compost and oak chunks. I haven't seen the second larv
  5. How's the ventilation in your container? Larva will come to the surface if there isn't enough air, which is a possibility if it's acting lethargic, so you might check to make sure the air holes aren't plugged up. It could also be preparing to molt or pupate and is wandering around to find the right spot. Sometimes larva will just hang out on top of the sub for a little while for no reason.
  6. My D. tityus pair has been burrowed under the substrate for months now, and I finally got impatient enough to dig them up for a photo shoot. The male in particular is stunning. The female has a duller color but hopefully she will be a good breeder and I'll get some eggs from them! I haven't been keeping them cold, so maybe now that I've bothered them they'll decide to come up and eat soon!
  7. I decided against opening any of the cells, put them back in the same container, and about a month later the beetles emerged on the surface.
  8. Don't worry about it, just keep it supplied with food and it will eat when it's hungry. If your weather is colder now it may just be slowing down a bit and won't be requiring as much food.
  9. They will absolutely eat as much jelly as you will give them. I had a female that would eat through an entire jelly in a night and still be stuffed in the cup in a food coma the next morning.
  10. Males are generally smaller than the females, and males also have tiny hairs on their antennae. Here are pics of mine for comparison.
  11. Yes, they were from BIC. Elytra issues are usually caused by the beetle not being in the correct position when it emerges from the pupa. It lies on its back for too long or rests against something that dents the elytra before it has the opportunity to harden correctly.
  12. They either got the antennae caught on something or they've been having disagreements. It could also be age related -- older bugs tend to lose antennae and legs. They'll do just fine without the antennae.
  13. More info: https://cals.arizona.edu/classes/ento596c/topic/session4.html
  14. Because they weren't created, they evolved. From beetles that at some point had use for wings.
  15. Welcome to the forum! Blues are one of my favorites too. I highly recommend all of Peter's desert beetles. They're fascinating to watch and are quite communal -- I have a desert tank with blue and black death-feigning beetles and various assorted desert beetles (and occasionally velvet ants) from Peter and they have no problems living together.
  16. My male M. punctulatus eclosed this morning. I've been keeping an eye on him all day and he appears to be doing really well. Once he turns entirely black I'll be putting him into his tank, although I imagine he'll just dig down and hide for a while longer instead of eating. I think the female I have is about a week behind him in terms of development, and I have another one still buried in its pupal cell, not sure of sex on that one. From everything I've been able to find on their care, they're similar to D. tityus in their needs, so I have some brown sugar jelly and hardwood sub
  17. Presumably this is a secure government website you're submitting the information to, yes? If it is I wouldn't worry about it.
  18. The sides are actually tighter than the photo makes them look, I had a light right overtop of it for the photo. But I agree, I think I made them a bit too wide. I'll give it another shot. Thanks!
  19. I had to remove two of my M. punctulatus pupae from their containers -- one had mites and the other one had mold working its way into the cell. I removed the mites and the mold doesn't seem to have harmed the pupa, but this is the first time I've had to remove pupae from their cells so I'd love some input on whether I'm doing this right. The floral foam I got doesn't seem to hold moisture at all, so I'm not sure if I did something wrong there or if I just got crappy foam. :/ I surrounded the dry foam with moist coco fiber to keep some humidity in the container but I'm not sure if that's go
  20. That sounds about right to me. I haven't kept track but all the L3 larvae I've gotten have pupated quickly, and my captive-bred larvae get bigger at a pretty rapid rate. I'll have to keep better track but depending on temperatures and whatnot your turnaround is probably a few months.
  21. I haven't the slightest idea! The second one emerged, and it does indeed have screwed up elytra, so once they start mating I should be able to sex that one easily depending on whether its on top or bottom! Aside from not being able to fly (I think, it hasn't tried that I've seen), it seems fine. The other two have eclosed but haven't crawled out of their cells yet.
