  1. Just regular oak substrate. very well fermented. Nothing special really..lol. I had some A/C problem here and had my place going well over 100˚F during the day for about two weeks, and most larvae died. (as well as many other adults and larvae of other species). But those Dyscinetus morator survived has reached L2 and L3. I think I heard they feed on grass root to develop, but... I guess that is only the case in outside, not with man-made substrate with more nutrition compared to just dirt out there...
  2. The peak adult flight period for Strategus antaeus in Louisiana occurs from the last week of May to the first week of June, and adults have been taken from May into September. However, males seem to only be found in earlier time from May to June, and females are more broadly found until later time. The lastest I collected female was sometime in July from Natchitoches Parish. Most numbers I've observed in a single night was about 4 adult pairs. Most numbers I have observed in a single year was probably over 10 males with about 7 females within two weeks. Within Louisiana, I've collected numerou
  3. Good findings! It is always excite to know there is something in your town. I have quite number of dead Xyloryctes thestalus in alcohol. If you can collect couple adult pairs, would you be willing to trade with me? I'm located in Louisiana, and have no access to find them anywhere nearby. X. thestaulus I have are personal collections from Arizona, last year.
  4. I cannot believe you never found D. grantii while you are located in Scottsdale, AZ, and have been to that Home Depot in Payson for past 2-3 years...
  5. Here is a batch of eggs laid by Dyscinetus morator. I've probably collected thousands of these a decade, and this year is my first time ever attempted to rear them. It was interesting to see how they lay quite a lot of eggs in one spot, instead of here and there sparsely one by one. This is one of the largest batch I've seen while digging through a 16 oz container with fully filled substrate with about half inch space at the top. My specimens loved jellies, so I'm assuming each different jellies are differently preferred by beetles.. (of course, they are differently manufactured!) My subs
  6. Let me add more to what two above has said: Just because a particular beetle is hatched and reared in the U.S., does not make it NATIVE INSECT, especially when kept indoor by a person on purpose. If they are somehow introduced naturally, unintended, and reproduced in the U.S., they can be considered as "introduced species," but I haven't heard anything like that in case of scarab beetles in the U.S. Such things happening in Japan, has been a problem to agriculture they got more more and more pests to deal with... (messed up) Parents of those offspring were illegally brought in, so al
  7. I understand you would like to collect as much beetles as possible with low cost under $100, but that is rather ridiculous, as smaller sized, non-plugged light sources just CANNOT produce enough light or UV to attract various and numerous numbers of insects. SO it is quite difficult to attract and collect any larger sized scarabs you might want to see UNLESS you light it up next door to your beetle neighbors. Better equipment (with substantial knowledge, of course) = better result. Light trapping isn't just an easiest way to collect insects. IT REQUIRES A HUGE KNOWLEDGE. Those "ins
  8. It seems it depends highly in each individual from couple weeks to more than a month. Each species, each individual seems to have varying time spent in pupal cell as prepupal stage... If I remember it correctly, I think My D. tityus specimens have spent somewhere about 3 to 6 weeks after completely constructing a pupal cell until they pupated.
  9. This was rather an unexpected collection, didn't actually meant to collect D. tityus. I'll probably start collecting D. tityus near new moon this year. Maybe second week of month or so. I do aware couple females are recorded in this year in Louisiana, so yea, I'm sure they are about to start flying around. Just not the peak season yet!
  10. For those who do not aware of what Dyscinetus morator looks like: https://junsukkim.wordpress.com/2016/08/03/dyscinetus-morator-fabricius-1798-coleoptera-scarabaeidae-dynastidae/ This is what they look like. This species is very abundant where they occur. As a common morphological characteristics of tribe Cyclocephalini, Male has thicker frontal tarsi while females aren't. That is one quick way to differentiate males and females. I observe them in great number in UV light traps, and even from street lights. The largest number I ever counted was 400 in a single night from a street li
  11. Fortunately enough, we don't only have rearer/breeders in this forum, we don't usually discuss about what is right and wrong. I don't think I've ever seen one. Also, many hobbyists these days eventually major in entomology or something related, so it seems the views on killing insects are becoming less difficult topic to being around us.
  12. My first specimen of Dynastes tityus collected in Louisiana this year. They appear in Louisiana starting the first or second week of May, but their peak active time is around mid-June to mid-July. The biggest number collected in a single night in Louisiana with my colleague was over 15 specimens. I'm hoping to see that miracle again.
  13. Strategus antaeus male, collected couple weeks ago in Louisiana. Their peak season is about to slow down, and of course, a seasonal rainfall just started. Research on Genus Strategus occurrence in Louisiana can be found in ResearchGate and Academia, if interested: https://www.researchgate.net/publication/326583796_THE_GENUS_STRATEGUS_KIRBY_COLEOPTERA_SCARABAEIDAE_DYNASTINAE_IN_LOUISIANA https://www.academia.edu/37034989/THE_GENUS_STRATEGUS_KIRBY_COLEOPTERA_SCARABAEIDAE_DYNASTINAE_IN_LOUISIANA
  14. I majored in entomology, and focused on scarab taxonomy. I kill thousands of insects for research annually. Yes, I always, and ALWAYS receive message about "why do you kill them?" I preserve them to study their morphological characters in the best-possible condition. Old and dying specimens with no characteristic features preserved, has less worth of studies. I study and publish my research to scientific journals to share the information I found with others. Without biological taxonomy studied on any living things, NO FURTHER STUDIES can ever even be started. Our common sense of different
  15. Looking into southeastern Asia, you may find quite number of large species, about two inches! They are huge, nice! very hairy!
  16. If you are referring to these in the link below, then half yes, half no. These are flood light, so it will only shoot light one direction. https://lightbulbsurplus.com/hid/metal-halide-light-bulbs/self-ballasted/ If this isn't what you were referring to, please provide me a link or an image.
  17. My mistake. It has to be 400 watts ballast as well if you are using 400w light bulb. When you run lower wattage bulb with higher wattage ballast, your bulb very likely die (possibly burst out), and when you use higher wattage bulb with lower wattage ballast, the ballast will be damaged. Make sure you get the equal wattage bulb to ballast. Also, many electric ballast have a "range dial" where you can switch the power ranges from 25% - 50% - 75% - 100%. So if you have 1000w ballast, you can switch it to 50% and hook up 500w bulb.
  18. Noise does not matter with collecting insects, but yes, if it is TOO loud and if you are collecting nearby someone's house, yes, you will very likely be reported, and an officer who does not know the law very well will VERY likely stop you thinking you are doing illegal activity. You will ruin a day! It happens, and officers might let you go and let you do whatever, but sometimes, they will stop you. Again, if you don't already own mercury vapor (mv) ballast, there is no way to obtain one. MV is no longer permitted to be used. Here are couple Amazon items I can suggest. Not all of my
  19. As Garin has suggested, you have to keep your car on all the time if you are to use a car battery. Or it won't last long enough, and your car will be dead out of nowhere. If you are puchasing new unit of mercury vapor, no you cannot as a ballast for mercury vapor cannot be purchased anymore. You will have to purchase a ballast for metal halide (MH). If you are acquiring 175w MH, then you need 175w ballast as well (that sums up to 350w), then if you add blacklight (mine is 18w 24"), that will be 368w (if just one black light is added. I use three btw). SO you need about 400w power supplier
  20. @Oak The setup I mentioned in the previous post is from very long time ago, over 10 years. That's when I was a high school teenager. That setup however, attracted about 400 specimens of Euetheola rugiceps, away from any street lights. Two lights alone attracted that many specimens with about that many Cyclocephala lurida. By the way, that is the largest number I ever collected compared to any street lights I have ever been to. Nowadays, I just don't go collect any of those two genera, so I haven't collect much more than 100 time to time, but that huge number in the past is thanks to the
  21. In my experience, not a problem at all. I've reared two species from eggs to adults and reproduction as well using Miracle Gro and two-three different brands with nutrition capsule as well as perlites (white stone-like in size of about 1/8 - 1/16 inch) with NO PROBLEM. I reared Dynastes tityus and Strategus aloeus until emergence without any problem. You can use it for female to lay eggs as well. I reared hundreds of of D. grantii larvae with it. I never emerged any D. grantii only because I gave all my larvae away to colleagues and other beetle enthusiasts in past, and I'm currently rearing c
  22. 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...
  23. 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
  24. 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.
