    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!

    I managed to make some photographs of my new roaches: Corydidarum magnifica. The nymphs are still quite small (8mm / 0.31inch) and I took the photographs through the glass of their tank, so the quality isn't optimal.

    I just read on http://www.roachcrossing.com/major-life-updates-unanswered-e-mails-facebook-reboot-future/, that Kyle is getting things back in order. That's good news, especially for Kyle himself! I didn't know what had happened last year, but knowing know after reading his message, it has been quite a lot. Well, I wish Kyle all the best (and perhaps we should not swarm him with roach orders )! Kyle: if you happen to read this: Take you time, and I wish you all the best!

    This is great news and definitely a step in the right direction. I share your notion that Megaloblatta's oothecae are tough like bricks and must go through some kind of process in order to hatch. What was really interesting for me to read were the observations on diet preferences between adults and nymph. This means that they possibly occupy different habitats in the wild. Maybe the nymphs have a specialized diet, or are associated with other insects (termites, fulgorids). Another option is that they stay close to the mother and she directly feeds them or prepares processed food for them. I am not sure I would go this far, but it is not too far fetched when talking about cockroaches. In any case, well done on hatching them and I hope they do well!

    3rd generation produced some oddities; two melanistic males! Here's a pic of one For some reason its offsprings took around 6+ months to hatch.

    Around this time last year I got my first isopods from Captive Isopoda. I started with 20+ mixed P. scaber "Lottery ticket", a nifty idea where you get a random assortment of non-visual isopods from experimental cultures. They may or may not come with recessives for other genes, and what you get is a mystery! If you're into isolating for morphs or want a nifty display colony, these guys are great. I started with a mix of grey, dalmatian, orange, orange dalmatian, and one calico. Early on, I ended up with my first new morph, some lovely orange pieds! They're hard to get pictures of but I think this one's decent. They're much larger now and I can still recognize my original isopods. They're doing very well and it's fun waiting to see what they'll make next. Second picture is a little blurry, but you can clearly see the difference between an orange pied and a normal orange. It's pretty neat, each one has a different amount of white that increases as they age. The pied markings are much softer looking than the crisp spots of a dalmatian. I also just realized the mass of at least four orange isopods camouflaged in the upper right hole in the cork bark, that's so neat. I ended up with tons of oranges so I'll likely isolate them sometime and see if they have any hidden recessives...I have no idea what's actually making these orange pieds, maybe it's them, so it'll be a fun project to see if it is.

    I know this isn't super relevant as a subject to discuss, but I'm just so excited! My library decided to accept my purchase request for For the Love of Cockroaches by Orin McMonigle, and now they have it! I have never hit "Place Hold" so quickly in my life! I can't wait to learn all about roaches and finally decide on a species for my next colony!

    Hello there! I'm basically a complete newbie when it comes to invert husbandry! I'm a pet enthusiast, and own or previously have owned almost everything; dogs, rodents, birds, fish, farm animals, reptiles (well, only one so far), etc.. However I have little to no experience with bugs, but I will be changing that soon! In fact, VERY soon. I am expecting my first roaches to arrive in the mail tomorrow! They are Halloween Hissers/Elliptorhina Javanica. I'm very excited to test the waters of invert keeping, and I hope to try getting some more bugs once I get settled with my first roaches and am ready to add in something else to my collection. I'd love recommendations for other beginner bugs, roach or otherwise. I love wacky-looking and colorful ones!

    I've made a time lapse of their activity. It's rather low quality, but one can see how they move around (albeit at 125x their actual speed).

    I use a UV marker pen to mark individual roaches. With a cheap uv light led lamp (also used to check money) I can see who is who. That way one does not see the marks unless you use uv light. I also used that to count woodlice in the garden....

    I started with 7 adult hissers a few months ago. Since then, each of my 3 females has had a brood. The colony is thriving. I made an interesting observation about their eating habits. I've always given them carrots, along with a mix of oats and crushed cat food. The initial couple tablespoons of crushed cat food lasted a couple months when I only had adults. They'd eat the oats around it. This lined up with what I'd heard about their protein demands (that they don't really need much). The nymphs have opposite tastes. They're crazy about the cat food. They eat around the oats. I have to fill the dish every few days when it dwindles to stray oats and frass. It seems to be just the stuff they need, because they're bigger every time I look. Bolder, too, so I see more of them. The audible scuttling of all those tiny legs grows louder by the day.

    So far it looks like Corydidarum magnifica is mostly active during the day, and much less at night (diurnality). They often wander over objects, making them quite visible. I wonder if their shiny colors and looks are a kind of mimicry for some kind of foul tasting beetle in their natural habitat?

    Interesting info! I bought myself 10 Corydidarum magnifica nymphs yesterday. I keep them in an enclosure with moist coco peat and sterilized forest soil. I have provided pieces of bark. For food I've put in some pieces of apple, some fish food and a mixture of fish food + oak leaves + grass hoppers (all powdered, whetted to a paste and smeared on a piece of bark). They prefer eating the latter stuff (paste on bark) and the apple pieces. Temperature is 72 to 77F (22-25C). Air is humid, but with adequate circulation. First observations: they mostly reside on the bark and are not inclined to walk over the soil. The first activity data that I have (motion detection) suggest that they are also active during the day? Any suggestions are welcome! And I'll share my experiences if anyone is interested!

    Anyone wants to take a stab at identifying this Blaberus from northern Colombia? It is massive.

    Vermiculite COULD work in small amounts in a substrate mix, but honestly you'll be better off using just coconut fiber.

    I’m not an expert in Ancient Greek by any means but I do know the ‘planeta’ part of Periplaneta comes from the Greek for ‘wamderer’ or ‘to wander’ as this is exactly what the ancient Greeks called the planets, because the ancient astronomers noticed that the planets ‘wandered around’ the sky in relation to the other stars which always had a fixed relationship to one another. So you’re correct in one sense because the word planet has the same derivation, but Periplaneta strictly means ‘wandering around’ - which is also very appropriate for the species as it is often seen wandering around everywhere!! i have a smattering of Latin from my school years so I can sometimes work out what some Latin derived names mean but other than the tale above Greek is, well, all Greek to me , so I can’t help you with any of the others I’m afraid!

    That's awesome, maybe these massive roaches will finally become more common.

    I have a feeling the nymphs spend most of their time in the undergrowth, while adults tend to spend more time above the forest floor. So the smaller nymphs probably have a diet more similar to other roach species, I have a feeling they'll eat more grain based foods than large nymphs or adults.

    In my opinion roach chow is the best way to go i manly put oats, cereal, fish food and bee pollen in my roach chow, that way you can control what Is going in there diet, and it is much healthier, especially if you feed reptiles I would strongly recommend during roach chow, I could even make some up and sell some to you, cape cod roaches sells it as well. I’ll list off the dry foods you mentioned from worst to best cat food, dog food, chick feed and fish food

    Cockroaches are white following each molt and it can take a few hours for normal coloration to return.
