aspenentomology Posted December 27, 2017 Report Share Posted December 27, 2017 One of the most common beetles I find where I live (during the colder months at least) are Uloma spp. I've tried keeping them before, but ultimately they never bred. However, I have learned a lot since then, and have a few ideas about why I may have been unsuccessful. The reason I find them during winter, spring, and autumn, is because they hibernate in rotting logs (that's the only place I've ever found them). I was able to keep them alive until summer, where they became more active at night. This was when they all died. This leads me to believe that they might eat something other than rotting wood exclusively. I originally thought they exclusively ate rotting wood, as they dig tunnels into the wood and ate out caverns. Another possible explanation is that they only live about 8 months as adults and over winter as adults, being larvae (and pupae?) during summer. I'm not sure how plausible that is. So main questions are as follows: 1. What do they eat as adults and larvae? I originally assumed decomposing wood, but could they also eat fungus or dead things? 2. Do they require an overwintering period? I think the biggest mistake a made last time was not keeping them cold over winter. I know this is what triggers breeding in lots of beetles, so this time around I'm keeping them on my porch. 3. Have their been any documented cases of captive breeding? Is it challenging or are they not worth anyone's time? I'm really looking forward to breeding these little guys, and tying to isolate strains of color variations (black and red basically), assuming those are traits that can be passed down. Any answers would be greatly appreciated, or even just a link to a website/pdf with information. Quote Link to comment Share on other sites More sharing options...
