  2. Has anyone here heard anything lately regarding the existence of wild populations of the Ailanthus Silkmoth (Samia cynthia) in the United States? This species became naturalized in some parts of the eastern US following its introduction in the late 1800s as part of a domestic silk production plan that ultimately failed, but it's been many years since I've heard of anyone seeing one of these moths (outside of captive breeding) in this country.

    Last Night Collections

    I read from old references that authors collected hundreds of D. tityus on a single tree. I guess that wasn't exaggerating afterall... Wow.. in 2008? that is only 12 years ago... That's not too far ago.... I wish I can observe that many number on a single tree (or sheet) too...

    Found some larvae, possibly stag beetle?

    I am more than willing to trade. I currently have the larvae and a freshly emerged male and female. Let me know! thanks

    Found some larvae, possibly stag beetle?

    Ceruchus piceus is not a rare species, it is quite an abundant species in areas where they occur. We have Lucanus elaphus and Dynastes, Megasoma species available in the United States, and quite number of people are keeping illegal species, not native to the States. Not many knows or have an experience of domestic species of all kinds (reason 1: rare, difficult to collect in one region, reason 2: not visually appealing in size, color, shape. etc.). If you are interested in your own collections, then I think it is a great opportunity to know them. It barely takes any space to rear them. I reared Platycerus virescens in 50ml centrifuge tubes. I don't know whether adult females require rotten logs to lay eggs, but they probably do so. I might have friends who might be interested in those species, if you are willing to trade.

    Dynastes hyllus hyllus - Pupating Question

    Delays are usually related to substandard substrate.
  9. Hey , are you still active here?

    Found some larvae, possibly stag beetle?

    Ok, after collecting a bit more, I have well over 50+ larvae leaving many more for the natural population. Has anyone bred or cared for these beetles?

    Found some larvae, possibly stag beetle?

    Cool do people keep these or are they pretty much undesirable because of their size?

    Found some larvae, possibly stag beetle?

    Yes, it is stag beetles, and the adult beetle on your hand is Ceruchus piceus. There are many more smaller species of Lucanidae even in the United States. We have A LOT of species.

    Found some larvae, possibly stag beetle?

    Yes, it is. Look like Ceruchus?

    Found some larvae, possibly stag beetle?

    I found this little beetle in the wood with the grubs, is it a stag beetle? If so, it is the littlest stag beetle I have ever seen.
  15. Is the temperature of air surrounding larval container is the 16-32, and above 20" or the temperature of substrate is? Try keep them cold for couple weeks and then put it back to warm location (or to your current location). Giving them a temperature shock may lure them to pupate. Each specimens has their own time frame to built pupal cells and pupate. They just may not developed enough and not ready yet. Just because they are from the same batch of eggs, does not mean they will emerge at the same time frame.

    Making and introducing larvae to kinshi

    Once it is fully colonized (when sawdust become white entirely (not just partially), it is ready to be used. Your understanding is slightly wrong. The larvae do not feed on mycelium itself. they feed on substrate that has mycelium. Therefore, if the woods are completely break down, mycelium won't colonize anymore. Why not? Because completely broken down woods do not have ANY nutrients for mycelium to continue to colonize. SO once colonization is completed, you can add larvae into your new kinishi. YOU MUST AVOID IT TO BE FRUITED! THAT'S NO-NO!! Fruit, the mushroom that we know of, is containing most of nutrients of entire colonization, meaning your kinishi no longer has full of nutrients for your larvae. As soon as you see mushroom on your kinishi, cut it off and remove it. And an answer to your original question, it is rather unworthy to feed your rhinoceros beetles. Once it is completely degraded, meaning no nutrition left over, why would you feed a junk food? Wouldn't you want a rather larger (or at least well developed) beetles than poorly fed beetles? You would rather want to mix up a portion of still-active kinishi to the substrate your rhinoceros beetle larvae are already feeding on. HOWEVER, many studies have already been done that no kinishi actually do anything for the rhinoceros beetles, meaning it is completely a waste of time. One thing I want to mention regarding to your kinishi you are working on. The Kinishi commercially available in Japanese beetle stores are different from the kinishi you can make from the mycelium from mushroom stores. The commercial ones used for beetles can be considered as a variation of species. It is not a pure species of mushroom, it is a GMO fabricated for beetle rearing. So the result of your production may not be as good as the commercial ones even if colonization is very successful. Good luck with it! You are making one step forward for the beetle rearing hobby in the United States. I've seen couple friends of mine in the States has successfully colonized it and used it.
  17. You do NOT need kinishi for rhinoceros beetles PERIOD. You really don't. Kinishi don't do anything good for rhinoceros beetles.
  18. I found a ton of these grubs while breaking apart a moist rotten log. Does anyone have any idea what type of beetle these could be? They look like stag beetle larvae to me, but I am not sure. I live in Connecticut.
  19. Hi, I have been interested in beetles for a long time but just recently got back into them. Currently, I'm keeping tiger beetles, warrior beetles, and some common isopod species. The beetles that I am looking to get into are rhino beetles and stag beetles.

    Interesting arthropod-themed video...

    While I disagree with the message, that video does contain some awesome macro and time lapse photography. Very cool. Thanks for sharing, Arthroverts

    Hi, new here

    This is a great place to learn, welcome

    kinshi and substrate for japanese rhino beetles

    The permit is the USDA-APHIS PPQ 526 form. You can fill out an ePermits application and have it processed, but you are likely not going to get the permits for exotic beetles without a containment facility and could possibly receive a "cease and desist" order that would force you to kill your current beetles immediately. I would recommend that you either begin setting up a containment facility and then talk to one of the USDA entomologists directly to explain your situation (all the USDA entomologists I have talked to have been more than helpful in guiding me through the permitting process), or you could just quietly keep your beetles but not breed them (keep them in extremely secure tanks!). Once you do not have exotics, you could get the permits for some of the native species around the country, such as the Megasomas. They are indeed a magnificent species, but keep in mind that if it is coming from out of state, then it also requires a permit (it is likely to be granted).

    @Bruh, that's a beautiful (not to mention) large species. I'd ask to see pictures but I know how difficult it is to get clear aquatic photos, especially of mantis shrimp, ha ha. Thanks for sharing, Arthroverts

    Just a peacock mantis shrimp. He's got quite a bit of personality, pretty inquisitive little guy.

    @Bruh, gotcha. Nice! Mantis shrimp are fascinating creatures. What species do you have? Thanks, Arthroverts
