    This is great!! @stanislas the change of the circadian rhythm of Therea bernhardti (Adult vs Nymphs) is really interesting!! :-D ¿there was records about this before? This is great again and congratulations! :-D
  2. Yep, I already have some ooths in cups with small isopods (two species) and springtails.. they don't seems specially attracted for them, so the ooths use to have over them as many bugs as any other spot on the substrate.... hopefully they are slightly making their (supposed) magic :-) Yep... I already did it with other fresh Nyctibora ooths, I think it was too late for the ooths I had to open (...for the embryos seems too ready to hatch) Dankeschön!! I really like your videos BTW :-D!!
  3. Hello friends! Sorry for the long absence... :-p Well... I did it with entomological scissors and a lot of care. Next time I'll make pictures... I'm afraid I will have to repeat this procedure with my Nyctibora ooths :-( Yes! Actually in the wild I've never seen an adult over the floor... only very high in the trees; and on the other hand, I've never seen nymphs on the trees. Still could be casualty, I mean... I haven't spent enough time watching them in their habitat, but it looks like an behavioural pattern :-D Yes.... and yes :-D your feelings seems to be right hahaha... Thank you very much @Test Account! :-D I already have it... it is certainly a very good book! I'll be updating this information every time I've got news... But at the moment the nymphs are doing well, at least I'm pretty sure they are eating well :-)
  4. Yep... I've got that suggestion before, and I will try it... But Megaloblatta species lives in the tropic, inside very healthy forest with a lot of vegetation that keeps temperatures and moisture very constant along the year. And well, there's a rain season, but judging for the periodicity with the female laid eggcases (one every 2 months, that takes around 5 months to hatch) and the microclimates they seems to choice to lay eggcases in (very hidden)... I'd say they look for a constant climate condition But yes... I hope to get a good oothecae number with this generation and I will try it
  5. Hello friends! :-) Spoiler: Yes, I did it, but... Some months ago I've start my first topic here in the forum, asking for information about care and breeding of the genus Megaloblatta, to find that as it seems, there's not any available information at the moment, and... that every known attempt of breeding this genus has failed, specifically at the point of incubating their oothecae. First topic here: Now the news... As you can see in the other thread, I've started with 4 nymphs, but one died in my process to find their right food. Impressively the other 3 survived my clumsiness to reach adulthood. I've learned over this period that they could receive conventional roach food (cat/dog food, fish flakes... oats), but in very low quantity, and they really loved sweet fruits, specially mango and bananas. And the most important: the right protein source seems to be raw meat... I use chicken hearts that they eat with a lot of passion Fresh molted nymph: Adult female: The ooths are huge (between 4-5 cms) Between the 3 survivors, I've got only one female... that laid only 4 ooths during her life. And here started the tricky part.... for after around 5 months the first laid oothecae was spoiled, fly worms emerging from inside. And then the second one!!!... Of course I was doing it wrong. So I took the determination of dissecting the third oothecae to check out what were happening. And I've found alive healthy embryos forming themselves inside... so the real problem were during the hatching. I've been really careful at the moment of dissection, and the eggs inside survived enough to hatch :-) And they seems to be the first generation of Megaloblatta breed in captivity. Pictures (Notice the antennae shape... they are much shorter in proportion than in big nymphs... that's adorable!!!) I have around 40 of them... and I'm already finding new details about them, for example... they are not interested in the same kind of fruits than the big ones likes, but I don't want to provide any information about it until having a real experience with it. Personal conclusion: Of course dissection is not the right method to hatch these ooths, but I was desperate and it worked for this time... at least I have enough individuals (much more than at the beginning) to keep on breeding and try something better next time. I have already an hypothesis... It could be that the oothecae case is very strong and hard in some Nyctiborinae species (because some other breeders and myself have found the same problems with some of their species), so perhaps the oothecae have to undergo a process of degradation by the environment during the incubation, something similar to the scarification process in some species of plant seed's. I would risk to affirm that that's why, in this case, M.longipenis lay ooths in "dirt places" (for I've found my girl released ooths covered with substrate in really muddy spots). So at the moment of hatching the ooths should be weak enough to allow the nymphs emerge, which is not possible with the aseptic methods that breeders (including myself) use to use... I will try to incubate next generation really moist and with a lot of springtails and as always... I'm open to you suggestions :-) Best regards!
  6. I just do it one by one... hahaha This step is not necessary... is just for the females to take more advantage over the resources inside the tuppers :-D

    Are we keeping dung beetles?

    Well... I think it's pretty possible that cockroaches, even after many generations, keep some of the bacterial flora from their original habitats... But maybe it shouldn't be considered dirtiness, for maybe this could even be good for them :-P (...who knows). I think, as soon as the cockroaches reproduce successfully there's nothing to worry about. Another topic could be the implications of keeping unsuspected cultures of foreign bacteria, this could be bad for other colonies you keep and... for the environment in general. But come one... all the time the human commerce is feeding back (in big scale) the bacterial flora of the whole world :-p
  8. Good! I'll be careful with them... I use to find aphids over plants I already offer to my cockroaches :-)... and I'll add bird excrement to the "to do" list. If it works It would be a good excuse to start keeping chickens
  9. Good idea... I still have to check with Aphids!! :-D I will take a look into my garden... for sure there are many of them for us to try
  10. Well, I've already tried and... ¿Do you maybe remember the species of Paratropes you kept? I've tried offering Nauphoeta cinerea, Gryllus cf. bimaculatus and Tenebrio molitor (pupae and larvae) in different presentations= Sizes and... I don't know how to say it ¿vitality? haha I mean... I've offered dead, wounded (crashing their abdomen to keep some movement, but making impossible for them to flee) and live healthy preys. And well... in all cases with healthy preys they where not interested at all, except with T.molitor pupaes, for they were biting them... taking some distance when the larvaes started to twist. With damaged preys... they were curious and feeding on all of them...This as long as the prey don't do any aggressive movement. And this is why I've tried with completely dead preys :-)... In this case there was an even better response, showing a certain preference for N.cinerea nymphs. But it seems like prey size does not matter too much, more determinant was the position of the prey, because in all the times they preferred feeding on the ones that were flipped (I mean... legs up), I guess looking for the most fragile areas to start feeding on. On the other hand, they were not more interested in insects than they are in sweet fruits. At the moment seems to me like P.phalerata could be opportunistic (not predators), and dead insects could be a very good addition to their diet... and I will keep doing it, I have to say that is the first font of high protein they take from me. Thank you very much for the data!!! I'm still curious about the species you kept... maybe they have a more predatory behaviour
  11. WOW!!! Thank you very much for the tips!!! @Hisserdude Ohh... Yes, my personal experience it's been the same, I don't have any Megaloblatta or Nyctibora nimph yet... but several oothecae waiting and waiting . But the good news is I've got Muzoa sp. to hatch :-D So maybe they are not part of the subfamily curse haha... Is very sad to know Paratropes genus does :'( This is fantastic information... I will try it right now :-) Yes... you would not expect them to be predators! They seems to have very weak jaws, something for flower nectar and that stuff haha... I've tried offering raw meat at the beginning and they just ignore it, I've tried this because is really appreciated for my Megaloblatta longipenis. So let's do this...Thank you very much!! I hope the oothecae will hatch some day
  12. Hello there friends, I've started breeding these magnificent species. Paratropes phalerata is a diurnal cockroach that lives on live plants. In some literature has been cited as an important pollinator :-) I've been trying several ways to keep them... At the beginning I've tried to emulate an habitat with the same plants I usually find them on. But it's been a little tricky and not necessarily better in captive breeding. So at this moment I'm keeping most of the groups I have in small boxes, with good ventilation and moist substrate, and barks for them to perch on, just to keep looking for the best way to breed them (Different foods and that stuff)... They like sweet fruits like mango... ;-) I already got some oothecae, they stick them to... anywhere hahaha Sticky side: ;-) But this one on the plantae is really how they lay their oothecae in the wild: As I said before... barks seems to be just fine :-p Incubating eggs apart: Some other pics :-) This is a perfect display cockroach!!! is really funny to watch them walking around the boxes and kind of communicate each other by touching their antennae. They are visible and busy during most of the hours of light, but not like looking for an escape, rather just wandering around the barks and soil. Sometimes I watch them taking a determinate route and taking a bite of food in every lap Next step: A big planted terrarium for all of them, with dishes containing pollen, sweet fresh fruits and some other foods with high flour content ¿Has anyone of you breed these before? Your suggestions would be very grateful :-D
  13. Hahahaha!! Well, I will try to get all species of Periplaneta I can, but I'm specially crazy for those Periplaneta americana "White Eyes"...
  14. Hello friends, I wasn't sure about to start this thread, but maybe it could be useful for someone :-) I breed Red Runners using the same "cricket breeding model", and I've found that is a really organised way to breed this species. I guess it begins with the harvesting of oothecae. Every some weeks I carefully take the most oothecae as possible away to the colonies tanks. Sometimes I do this at the same time of cleaning session in the colony, so I can replace the dirty substrate (free of oothecae) after that. I use another bin with slightly moist substrate to put a layer of around one centimetre of Red Runner oothecae :-) At this point the growing tank should be ready for them to hatch and be free :-) I used to use crater pieces as ramps for them to get out of the incubator tupper by themselves; but mines use to be a little cowards and they takes their time to jump out of it. So I prefer to let the craters in and shake them out every some while They are a lot, and in some weeks it will be necessary to divide the colonies into different tanks, I use to change the dirty substrate at this point again, is really easy when you don't have to be careful of discarting any oothecae :-) And then they will have enough space to reach adulthood in a healthy way... I use to do another complete cleaning of the tank before they start laying new oothecae... it makes such the work less chaotic ;-) And at this point I make "the purge" ... that means to take away the excess of males to reach a sex ratio of (in appearance) around 1 male for every 5 females... I use them all for the current tarantula´s feeding session... I leave a satisfying video of some of them here... ...And well, from here the process start again... This way I keep my Red Runner colonies clean, separated by sizes and always ready to use! Bye!
  15. Hey friends, I've been breeding these since some time ago... Is the first Periplaneta species I've ever kept and I'm in love with them :-) The overpopulation in my colony works pretty well as occasional feeders... Ñom! She likes potatoes
