  1. What do you mean by "frequent care"? I do not like to disturb animals unnecessarily... And, IMO, it's not my situation, anyway... Fresh wood, leaf mulch etc. - and never let them to be dry, though always try to keep some difference in humidity btw two sides of an enclosure. For how long? In years? They're pretty slow to grow and breed, so, IMO, 2 - 3 years is only enough for one full cycle, and period, which seems to be long in years, appears to be not so long in generations. When they appeared in the hobby? In mid nineties, or earlier? Are there colonies, still t
  2. Hi All! Last week decided to clean and replace my colony of P.angustipennis cognata - and found that there was no more colony. One young-looking male, pretty sad, one definitely old female, plus several nymphs of different stages. And that's all. Communicated with roach-comrades, heard just the same: colonies declined. Panestias, Salganeas, some other species. I even discovered that mine appeared to be one of the most long-thriving, usually they declined after 3 - 5 years, one full generation. Mine thrived successfully since, AFAIR, 2011 or 2012, when I found t
  3. Never have seen tomentosa being an issue for roaches, even for newborn and molting. Isopods readily consume dead bodies, aborted eggsacks, food particles etc, but not living animals. Cubaris murina in my enclosures can sometimes be too numerous and active, probably pushing some weaker roaches off from the food, but not trichorhinas.
  4. It seems surprisingly rare though, taking into account usually inbred population type. Many keepers start their colonies from just several roaches, or even a single pair... And these colonies successfully thrive and grow for years, with very few aberrants.
  5. 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.
  6. 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.
  7. 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
  8. 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.
  9. 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
  10. 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...
  11. 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.
  12. 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...
  13. 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
  14. 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.
  15. 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
  16. 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 d
  17. 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.
  18. One of the most hard-to-make-and-maintain types of habitats in captivity, IMO. High-elevation type - cool, windy, with humid air and dry soil - is more tricky, but there're usually no roaches at 3500...5000m... It's definitely not for small enclosures, the only way to keep it small is to put inside a large tank. My colony of Cordidarum is thriving - very slowly increasing in number, from about a dozen mixed adults and nymphs in 2012 (WC brought from Cambodia) to slightly more than 40 adult females now. Usually they sit on the underside of pieces of bark, large dead leaves etc.,
  19. I have - for years already #1: Pycnoscelus sp. (initially it was smth like indica, then nigra came with additional substrate, now they're happily coexisting) + Gyna lurida + some small greenish-grey striped millipede from Malaysia + some unidentified grey woodlice from Lao + Trichorrhina tomentosa + some small darkling beetles from southern Zagros + some small xylobiotic Myrmicinae ant from Thailand (nests under dry bark on twigs, migrating to new place when twig is being diminished by companions). Enclosure about 20l, moderately moist, with coco-soil, oak leaves, dead oak/willow twigs w
  20. For Scaurus - just a piece of wood - soft enough for larva to gnaw a cavity and damp enough for pupating and beetle emerging. They do not eat it, only use for pupating. Adesmia and Blaps larvae usually pupate just in damp soil - under stones, e.g., but may use wood, too. I tried to use plastic tubes etc, they definitely do not like anything but wood... Adesmias look unusual, but, IMO, Scaurus are the most impressive, with their thick legs with hooks and all this, they've somehow prehistoric appearance Don't know whether it's possible to obtain exactly these beetles in the USA,
  21. I use agar jelly for ants as a staple food, based on Bhaktar mixture. For others - as long-lasting water source, especially when leaving for weeks. Agar needs boiling water to be dissolved, so after it dissolves, it needs to be cooled down - to 50...60C, and then I add smth like carrots or banana juice. Store in freezer, at -18C, no longer than 3 months (usually 1 - 2). The nuance: agar itself is undigestable, so it goes out with feces and becomes part of the soil in vivarium. It's neutral, and decomposing very slowly, so - has something to do with overall humidity.
  22. IMO, they tend to use all the space you provide - at night they'll climb branches, daytime stay on/under bark pieces on the bottom.
