  1. Usually they do use bark, egg packs etc as above-the-ground shelters. If there're no such things in your enslosure, they try to use walls.

    Panchlora sp. "White"!

    I usually cool'em down a little - e.g., having usually +26...+28C, I bring the box to +18...+20 for a night or so, after it they're less active and do not even try to fly. It's also the way of, e.g., changing substrate or taking a group.

    Gyna Centurio building a colony!

    The 2nd pic looks as if it's too damp in your setup - isn't it? Centurions are by far not the driest roaches to keep, but neither they prefer to live in a swamp... They're not especially choosy. Mine are prospering in a 10l plastic box, almost all the time being hidden in substrate, eating voraciously everything edible. Only males sometimes are active above, fighting and even try flying. If you want to make things better, just try to keep'em in long (not large, but long) container, making one side moist and another - dry, and

    Gyna centurio mite problem

    The easiest way to get rid of these mites is to use predatory mites, usually it is Hypoaspis miles (now it's Stratiolaelaps scimitus, but the previous name is in use also). It's widely accessible as one of the "tools" for biological pest-control. It successfully eliminates all such creatures, and to some extent can even control larger pests, such as phorids (AFAIU, by eating their eggs and newborn larvae). Alas, in small setups it also destroys soil in-fauna, such as springtails etc., but does no harm to roaches, even with small and tender hatchlings.
  5. Yea, good problem. Phorids are disgusting, for me the one and the only way of eliminating them appeared to keep all the colonies in tightly closed boxes, with ventilation windows covered with steel mesh... In open setups they appeared anyway, with or without cleaning. But for removing excess dead protein "cleaners" are really useful... In less dry conditions woodlice work well, sometimes extremely well, especially Trichorhina with Cubaris murina. They eat dead roaches, roach food, prevent mold and somehow clean the substrate from mold etc. In dry enclosures I have several darkling beetles, one of them is, AFAIU, Alphitobius diaperinus, very common lesser brown mealworm, others - unknown, mainly arrived occasionally from Asia with plant material. They're quite useful, too, eating dead roaches and food leftovers. And they don't touch eggsacs, but are quite capable of attacking molting roaches, especially when it's really dry in the setup.

    Unusual things cockroaches eat

    Flowers are very good as food for most roaches! Dandelions, roses, clovers, lilac... Acorns; pumpkin, squash, watermelon, melon seeds; soft ash and maple seeds... Some (protein-loving) roaches readily take unfrozen fruit-flies, mealworms, dead inverts like theraphosid males...
  7. Yes, sometimes they're quite noticeable. My byrsotria definitely prefer protein-rich food, schultesia take only plant-derivatives, etc.. I don't use cat/dog food, but give fish flakes with algae, at least cleaners consume them readily.

    Fungus Gnats

    I think they're, in general, inavoidable... Not clouds, but 1 - 2 - 3 I see almost always in my enclosures, though cleaners like isopods, springtails and sometimes even snails seem to utilize every noticeable uneaten food. To diminish their activity substrate must be drier, without any remnants of edible organics. Either in roacheries or in arachnariums it's barely achieveable...

    Rhabdoblatta sp.

    AFAIU, no; black from above and dull-orange below, with brown eyes. But I've already 2 males with such a blotch, separated them with one black female, mb, they'll produce smth interesting :) In fact, took them in november, 2017, in southern Lao. Dry sandy riverbed, moist but already without water, and nymphs were quite abundant but very local, found'em on only one patch, mb 2 - 3m in diameter, anywhere else around, in absolutely identic places, found nothing. From february to march successfully molted into imago (only 1 or 2 died for uncertain reasons), and now there is a crowd of newborn roachlings :)

    Rhabdoblatta sp.

    Two males (female looks just like male, but is noticeably larger and somehow bulkier). Surprizingly, one with orange blotch is by far not freshly molted.

    Rhabdoblatta sp.

    They're quite social.

    Goodbye for now...

    Hey Man, it's not an issue - it's just Time I've lost and sold my collections repeatedly, 'cause of wives, children, army services, long-time errands etc., etc.. Then I've returned - and beasts have returned, too - some new, some old, but inevitably. Now I'm 47, my elder children're 23 and 22, my young daughter is 2, and 5 yrs ago I've brought a termites colony from a trip to Vietnam And now I've half of a room tightly packed with enclosures So - it's smth like Midi-chlorians in your blood - if you have it, you can't deal without all this bugmatters

    can you ID this Roach?

    I have some, too They're quite common from southern Myanmar through Thai, Lao, Cambodia to Vietnam, mostly forest-dwelling, but also I've met'em in gardens, on the ground, under logs or low on tree trunks. Adults - from september to ?november? [I haven't been there later], nymphs from 10mm - from the end of april or beginning of may... 40 - 50mm, blueish-black thorax|wings, dark reddish-brown abdomen. Pretty impressive roaches, wary, quick, and - unexpectedly - pretty fragile creatures. This whitish substance is really a glue, mb, it's toxic, 'cause after contact with it ants die quite quickly, in several minutes... They're not easy to catch, and even more tricky to handle, 'cause of this glue. They imediately smear with this glue everything around, including themselves, and die :| And I've failed ingloriously with eggsacs - not a single hatchling after half a year, though embryos appeared to be intact but dead. Maybe, they need smth to be stimulated.

    Non-roach bugs for domino setup?

    I think you're right, though... I've never kept Arenivaga by myself, but have a long and quite successful experience with different Polyphaga species, from Magrib and Eurasia. Kept them initially almost exclusively on sand - without any problems (later switched to coco and other organic substrates - they're just much more convenient for me). IMO, the main issue is that they really do not spend much time in dry sand, but in moist deep layers, emerging at night for feeding, mating etc. - so, in fact, they meet such a hard conditions only sometimes and for very short periods. Rodent (or tortoise) burrows are always full of life - even without rodents themselves, but they're not always available. And, as far as I've seen, in such dry sandy areas any sheltered and "unsandy" place (leewards of any types, especially with some plant material - dry grasses, fallen leaves, dry twigs or logs...) always attracts life. Heavy clayish areas are covered with cracks and fissures, and they form an excellent network of shelters, too - so if surrounding space itself looks pretty unfriendly, you can find many interesting things while investigating these "hidden space" - sometimes of unexpectedly large size
