  1. I have noticed the same thing in reverse: many nocturnal arthropods do not react to any kind of dim lights. With many of the poor-vision species, especially web spiders, even bright light fails to trigger a response; they often even continue obliviously chewing prey.
  2. I have plans to do a similar thing too! unfortunately, they are only plans
  3. Also, @vfox and @Hisserdude: the thread that Tleilaxu mentioned has pics of japonica in it by CodeWilster. I checked his shop (theroachlab.com), but japonica is currently not for sale.
  4. I've searched here and beetleforum extensively, and I have not found any guides to making rotted leaves (though wood fermentation instructions are rather common). Here is my attempt, which some of you roachkeepers may find useful. Currently they have been freshly put into containers, so I will update as time progresses. https://sp-uns.blogspot.com/2018/02/i-attempt-to-synthesize-rotted-leaves.html
  5. @Tleilaxu! By the way, there was another Periplaneta photo thread around here. Shall we revive that one instead?
  6. My loquat leaves appear to be rather fresh off the tree. https://sp-uns.blogspot.com/2018/02/rotten-leaves-update.html
  7. Mmm, buttery (as insect hobbyists, our purpose in life is to drool incoherently at pretty species)
  8. Ignore the Coniontis; its dry lettuce is just for fun Since leaf fermenting hasn't been tried before, we cannot know for sure until the results show themselves. I will think about adding a third container with both dirt and leaves, just to experiment.
  9. Thanks, all.
  10. Does anyone know of a simpler method to make (heavily-ventilated) mesh lids that doesn’t involve electric drills or buying stuff?
  11. I leave dried lettuce in the Coniontis jar Interesting, I may have to dig a lump out of the garden. My 2015 leaf-rot attempt did produce isopod-edible stuff; have you personally tried making rotten leaves yourself?
  12. a particularly rank and soggy forest The dry leaf thing is good to know, but many beetle groups do prefer their leaves well-rotted.
  13. Hey

    Welcome! Bugsincyberspace enjoys using Therea domino roaches and other colorful species to remove fear.
  14. Agreed. I have had some Zophobas adults slow down and mysteriously die after molting, though, so I was speaking from experience. The plumpness is a good sign, if the roach refuses food for a few days it may still have energy to recover.
  15. I'm in CA, so...
  16. It seems that wrinkly wings should have no statistically significant bad effects on roaches. Tenebrionid beetles with really messed-up wings can live normal lives easily, so When insects become lethargic and slow-moving, often they are near death. If they eat, they often recover from their weakness. If they refuse food, they are usually doomed to roach heaven, no matter how hard the keeper tries to save their lives. If I were you, I would isolate that female in a comfortable small box, try stimulating the palps with fruit/water (more digestible than normal roachfood?), and hope for the best. There might be a small chance your peppered roach makes it, so good luck!
  17. I particularly like this specific image. The contrast between the enormous adult, new young, and springtails makes it such a balanced and elegant photograph.
  18. Many arthropods are known to produce powdery coats, including the isopod Porcellionides pruinosus. Thus, its occurrence on hissers isn't too surprising.
  19. The technique you mentioned holds true for non-cryptocercid roaches, and dubia isn't a cryptocercid. Some roachkeepers are known to feed off their excess males, and I wouldn't be surprised if one of these decided to just sell them off as feeders instead.
  20. I would assume that wild dubias show the same amount of variation that captives do. With some insect species, every individual looks the same. With others, minor pattern/color variation is a common sight. And then there is the infamous Harmonia axyridis. In many insects, the males reach adulthood faster than the females. This seems to be because they are smaller and thus grow faster. It is possible that: 1. Your female nymphs have not reached adulthood yet 2. You have adult females, but you don't know how to tell adult females from nymphs Don't worry too much, I'm sure that your dubia sex ratios are not skewed at all.
  21. This would presumably only work if the area has a dry and a wet season. @Xenoblatta obviously has access to them in the wild, and I'm curious to know what specific conditions (temperature, humidity, seasonal changes, location, so on) oothecae and nymphs are normally found in, the more precise the better. Cockroaches: Ecology, Behavior, and Natural History (online for free) states that nymphs may ail/die in conditions adults seem fine in, for reasons I forgot. Trying to replicate the environmental conditions wild oothecae/nymphs are found in would prove useful for everyone if they were imported to the US in some distant future.
  22. Outreach is good I have noticed that not all people will respond to the "harmless roach" tactic, though. Many will simply lose their abilty to think in straight lines as soon as the C-word is mentioned.
  23. But putting "carabid" in "carabid ground beetles" can't hurt.

  25. PPS: Don't worry, this is the correct section to post this.
