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!
Hello there everybody, I'm new in this forum; I've just enjoyed some threads and looks very helpful... I'm an enthusiastic on the cockroach breeding... and recently I've got an small group of non-adult Megaloblatta sp. I've been keeping them as any roach from wet places; but I'm afraid to mess ir up with this species... it's very hard to get them. So guys... Do anyone of you have some experience on the keeping of this genus? Or know about someone who has successfully breed this roaches?... Feel free to guess the best way to go with them... real experiences would be immensely appreciate. Picture note: Of course that's not the keeping cage :-)
