  1. That last picture is of the larvae. I was shining an led flashlight on it as well. So I am correct then, the first two photos, the orange circled organ is ovaries?
  2. And then here is the one I have been keeping, nothing seems to be visible. Not sure if any breeders can confirm, but seems like this should be a male if the article in the first post is correct?
  3. Here's the second grub I found today, also with that yellow/orange organ visible.
  4. So I was not able to compare my larvae to anything, until now! I examined my larvae for maybe 10-15 minutes, could not find any sign of the ovaries. However I also could not definitively figure out if I was able to find the black dot for the terminal ampulla, it seemed like it was possible but depending on how the grub was squirming about it was sometimes maybe possible I saw something other times nothing seemed visible. I was able to finally get out to the forest I found my grub in, and my goal was to find a few more grubs to compare it too. I found two grubs almost immediately under white rot logs, flipped over to see their back, and immediately noticed this yellow/orange oval shaped organ. So with that said, obviously I can't be 100% certain until it pupates, but is this a pretty good chance I have a male?
  5. http://maria.fremlin.org/Fremlin_Hendriks_EB_2014.pdf I was reading the above article, and on the second page it mentions two ways to sex a cervus, is this universal for all stag beetle grubs, for example north american species? From what I understand the first method, looking for the black spot for the terminal ampulla, is done for other grubs, but never heard it used for stag beetle larvae. The second method is new to me, but seems like a much easier method assuming you can correctly identify the organ.
  6. It shrank to 1/8th its size? Either you measured wrong or you have more than one beetle.
  7. Yeah I did some searching after I asked and someone was explaining brown rot doesn't have the nutrients that stag beetle larvae need, so I went and got what I'm assuming is white rot, kind of a white/pale yellow color, very flaky but stays in long strands, unlike the brown rot which just crumbled. Hopefully I got the right stuff, there looked like there were signs of something eating out the underside of the log I took it from, and a few random holes under the log in the dirt as well, which didn't seem to lead anywhere, so perhaps some larvae used to live there. Yeah, there was some softer wood nearby I'm going to try using that. I think the part that surpised me the most was that there seemed to be an ant colony under the wood as well, I'm surprised they didn't kill the larvae.
  8. Awesome thanks. The two stag beetles that apparently live in my area are those two, so I guess it will be a surprise which one. The log I found it under was still pretty hard, so I couldn't take any of it with me, but I found some reddish wood that is pretty brittle nearby, will this make a suitable substrate for keeping it happy? Do I need to add soil or will pure wood work? I can provide photos if needed. Not sure how picky of eaters these guys are.
  9. Is anyone able to confirm if this is stag beetle larvae or not? Found this one under a log, there was a smaller one as well. I have seen bess beetles in the same forest so I'm just trying to confirm it's not one of those. It looks like it has the Y shaped anus with two big lobes, which I read is exclusive to stag beetle larvae but not sure if that's accurate. Also what kind and gender? (I read they might be indistinguishable so no worries if not)
  10. Ah I think the second trap was just the first image I found, I didn't realize it had that top section. The one I saw before was pretty much that with a lid type thing at the top to keep out rain and so bugs that fly up will hit the lid and then drop into the bottom. That is interesting that american stag beetles aren't attracted to the sap like european or asian species. It seems from google searches there is very little info on the american species which is kinda sad and suprising.
  11. Hello all, Just had a few questions, apparently there are elephant stag beetles where I live, so I've been kinda on a mission to find some. No luck with beetles but I think I did find some larvae of some kind of stag beetle. I was considering hanging some traps but had a few questions: 1) What is the best time of the year for these? I'm not sure if I'm too early, I started looking mid May. 2) Has anyone tried using these bottle traps or window pane traps? I was thinking of trying them baited with ginger, apparently european stag beetles were baited pretty well with ginger, I'd assume US stag beetles are the same 3) Any general tips for finding them without traps? I have been trying rolling all logs I can find, only found two larvae, not sure if they will be hiding under logs or just on the ground/trees.
