  1. I use a COB LED flashlights that works with 18650 batteries. If you get genuine 18650 battery with a good quality COB LED flashlights, it works very perfect! This is a link to the product I'm using: https://www.amazon.com/gp/product/B086626C4V/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 And by the way, there are a lot of fake headlamps out there (such as: stating they can light up to 20,000 lumen, but actually not). So watch out for that. Most of them are priced very low.. The good COB LED flashlights with high lumen are usually stays around 20 dollars or over. I ha
  2. Not me, but we do have couple Canadian members in the Beetle Forum come and goes. Since most of the members are based in the U.S. it seems it is rather challenging for members from different countries to keep up their membership here.
  3. If you are referring Dyscinetus morator as the rice beetle, they do play dead. A lot of insects actually do.
  4. The best dung beetle trap design I've ever seen was trap constructed by Vernon Antoine Brou Jr. (Abita Springs, Louisiana). Below is a link to his FB post, with a lot of discussions under comment section too. https://www.facebook.com/photo/?fbid=110003892451692&set=a.107115286073886 I too used his trap design to collect hundreds and thousands of dung beetles or any insects attracted to animal/human feces, including Phanaeus vindex, Onthophagus taurus, Onthophagus hecate, Onthophagus medorensis, Deltochilum gibbosum, Copris minutus, Canthon chalcites, Onthophilus, Geotrupes blackb
  5. It is commonly known as may beetle species under the genus Phyllophaga. They are often appear in May. (but can be found from April to October, and all depends on weather, regions, species, ...). Hard to tell species as the picture barely shows any features.
  6. Go ahead and place the larva into new habitat. If you can, grab some old substrate and mix with new substrate. Or am I not understanding your question enough?
  7. Many thinks that the targeted species brings the harm to the native species, but that is less likely the primary reason WHY they are prohibited. The most primary reason to prohibit importation of alive organisms from other countries is the disease and pests that comes with it, which can actually do more harms to native fauna and flora. It sure can be differ per what the species is, but in case of insects, which interacts with plants A LOT, plant disease and pests are the primary reason.
  8. Where do you keep your beetles? Probably Indoor, right? They wouldn't know whether it is spring, summer, fall, or winter because the temperature is pretty stable throughout the year inside your place. If you keep the enclosure rather cold, they will be inactive until warmth comes back, but if you keep them warm, they will very likely start feed and be active right away. By the way, I don't think D. tityus really require "cool period," as this species aren't really sensitive to all that. How much (as in amount) tortoise feces do you have to provide to Phanaeus vindex? Do you have a large a
  9. 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...
  10. 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
  11. 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.
  12. 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...
  13. 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
  14. 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
  15. 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
  16. 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.
  17. 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!
  18. 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
  19. 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.
  20. 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.
  21. 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
  22. 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
  23. Looking into southeastern Asia, you may find quite number of large species, about two inches! They are huge, nice! very hairy!
  24. 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.
