  1. Hi everyone, I am a first time owner of 9 Dynastes hyllus hyllus babies since I got them as L2s in May 2019. 3 of them have pupated (respectively in Jan, Feb, then Mar 2020). All girls, all beautiful and looking healthy. Just a few hours ago, the one that pupated in January has emerged. She did a stellar job growing up. Here comes my question: my other 6 are still in their larval stage, lying around doing nothing. What’s going on? They turned L3 months ago, around the same time as the 3 pupated ones. The 6 of them haven’t been eating for months (over winter), just like the other 3, only that they haven’t pupated. They haven’t even made their pupal chambers yet. They are still alive as they move around every now and then. I keep all of them at around 16-23C. As I suspected that it might have something to do with the temperature, I have since turned up the heat for them, so they are consistently above 20C. Please, if you know anything that might explain this situation, I would really love your help. Thank you so much for your support and for creating this amazing community.
  2. I've been watching this dark bump get larger on this larva. Has anyone seen this before? It seems to be fully attached, but I haven't tried to remove it or anything. Maybe the substrate got stuck under the skin?
  3. Hello Forum Members, I have been approved as a member of beetleforum.net. It's been long enough since I applied that I despaired of ever making it in this grouBut I have to say that I actually like the fact that membership is not instant and automatic like some other online groups. In 1987, right out of college at UCSC in coastal California, I packed up my VW squareback with a few possessions and moved to Arizona. I had no job here, I had no place to stay, I had no friend's couch to crash on. One of my first destinations in Arizona was Carr Canyon in the Huachuca Mountains of Cochise County. Unbelievably, there was a sign on the outside of one of the last homes before entering the national forest, "ROOM FOR RENT." I stopped in and talked with the young couple who were renting the home. Before I left that day, the couple told me to bring my car around and move my stuff inside. I was able to run my lights every night during that summer and into the fall that year. I have lived and worked in Arizona since that time. Though I started out collecting beetles and butterflies as a boy, in my teenage years I moved to large moths and that has occupied my time for a few decades. Professionally, I worked for nearly 20 years as a botanist and most of my science publications regard plants. I have been deeply involved in working on the floristics and faunistics of the state of Sonora, Mexico. I continue to be fascinated by the region-- from the tropical deciduous forests in the extreme south where Morpho butterflies and Golofa (only a 9 hour drive from Tucson) occur, to the dry and hot deserts of the western coastal plain. I have reared Megasoma and Dynastes successfully and would like to continue rearing these and other groups. I am rearing Phanaeus now, too. There is an undescribed species of Dinapate south of here that I might attempt at some point. For now, with my interest in biogeography and ecology, I am preoccupied with local beetles (southwestern North America including Northwest Mexico), especially Megasoma. I am very interested in doing field prospecting for undiscovered populations and observing behavior in the field with a special emphasis on hostplants of adults. I am excited to be able to establish contact with other hobbyists who collect and rear. And I will end by saying I have no issue with collectors and those who sell insects, alive or dead. I do it myself. And, it is true now as it has been as long as collecting has been a hobby, that most of the information we have about nature has been collected by so-called "amateurs" and not professional scientists. The greatest disservice a country can do for the state of knowledge of it's natural resources is to forbid its citizens the ability to engage in hobbies in the natural sciences. Best regards, Mike in Tucson
  4. I was wondering what the maximum temperature that D. tityus larvae can be raised in. I was also wondering do higher temperatures lead to shorter development time? I have read it causes the lifespan to shorten, but does it also make the larvae go to maturity quicker? Are there conditions that are known to speed up development time or to slow development time?
  5. Hello all, I was wondering what the maximum weight of a D. tityus and D. granti larvae would be.
  6. Hey, guys. Long time since I posted, but since summer is just around the corner, and my A. dichotoma (Or Trypoxylus dichotomus? Which is it?) are pupating soon, I'm thinking that I need to get them some friends. So, my question is: where is the best place to find imago and/or larvae of D. tityus in southern Mississippi? Hattiesburg, MS to be specific. And are there any other cool species I should be on the look out for? Does Lucanus elaphus live here?
  7. One of my female and my male D. tityus have been appearing more and more on the surface lately, and either they've been eating their jelly or the jelly has simply shrunk (not sure if this happens or not), so I went ahead and transferred these two to a 3-gallon terrarium with about 2" of organic compost in the bottom for breeding purposes (hopefully). The male burrowed immediately and hasn't been seen since, but the female actively explored the tank for about 90 minutes (she was particularly interested in the corners, something she'd done in the larger tank before) before diving headfirst into their jelly (literally). She was out of it 30 minutes or so later when I went to sleep, but when I woke up she's buried in the jelly up to her elytra again. I was actually afraid she'd unintentionally committed suicide, but a prod on the behind proved she's still alive. I apologize if I'm being overly concerned, but as this is my first time with rhinos, their behavior is all new to me. Is this something to be expected from her; literally gorging in preparation for mating and egg-laying? Or is this potentially stress-related behavior?
  8. My female D. tityus have finally decided to come to the surface and start exploring every now and again. The male is a little lazier, but he's made a couple surface appearances. They've barely touched their jelly, but hopefully they're not too far off from starting to mate. Managed to snag a decent picture of one of the females today. The picture of my male is from unboxing day.
  9. Ok... so... stupid question(s) time. What's the best way to remove a stubborn D. tityus from your skin without hurting them? Do adult D. tityus tend to burrow or hide for a good while after shipping (similar to how tarantulas will)? About how long do D. tityus attempt to overwinter if kept in a room temp environment? As I've mentioned elsewhere, this is my first time with any sort of rhino beetle, and since they burrowed the second they touched the substrate, haven't touched their jelly, and we haven't seen them in a week now, the wife wanted proof that they were still alive, and seeing as she lets me get away with a lot in terms of hobbies, I felt compelled to oblige. I feel pretty bad, because I'm pretty sure I scared the absolute crap out of the female I found while gently digging through the substrate, as she latched onto my hand immediately, and wasn't budging even when presented with an easy path back to the substrate. Giving her gentle prods from any given angle just made her double down on her grip. I finally just literally settled down with a book, with the hand with the beetle in the tank, and she finally decided to let go and burrow. tl;dr: I accidentally scared one of my D. tityus, and spent the next hour as a beetle perch.
  10. From what I've heard over the years it's not hard, but I can't seem to do it. I saw a female Eastern Hercules Beetle in an elementary school playground back when I was in elementary school (in Jefferson, MD). I'm 26 now and I've been searching for another one for years now with no luck. I always hear they're typically found at playgrounds and parking lots by accident. I've been digging under old logs and stumps in the forests around my home; (Which is nearby the elementary school I went to.) and although I have found many different beetles during this hunt, I still have yet to come across one of these beautiful creatures. I've been out almost every night looking around light poles, but perhaps it's still too early in the season to find anything large just yet, despite I've found many different species by this point. At the moment I'm taking care of some Bess Beetles at home, that I found in a colony nearby the home, and they've been a pleasure to have around. Anyone got any tips onto how to run into a Dynastes Tityus? They're my absolute favorite beetles and I would love to see some again, and even start caring for them if I can.
  11. This is the only D. tityus I have ever found in FL. I found him back around February outside of East Orlando. Hes been growing much quicker than all of my other D. tityus larvae. All of my other D. tityus larvae are between 16-22 grams but this big boy just pushed 27 grams not too long ago. I hope he will get a little bigger before he pupates. I never feed any special supplements to my larvae. Only decayed leaves and wood that is collected locally. It will be interesting to see how big he will be once he becomes an adult. Has anyone else raised any huge D. tityus before? Here's a Comparison pic of the 27 gram larva next to one that is 17 grams
