    can you ID this Roach?

    Hey, It may be Melanozosteria, but I'm not totally sure

    Schizopilia fissicollis

    Hey Everyone, Indeed, the first Schizopilia were collected in Mitaraka, French Guiana. I've been in touch with the Museum since 2016, and contributed to their research by giving a large amount of individuals from diferent species. Later, the contacted me about this species. The F1 generation was close to be adults but there were no research planned for them, so they were not planning to keep them and asked me if I wanted to receive them. The only thing I've seen about them was a black and white illustration without scale... You can imagine how crazy I was when I saw that pronotum! The terms were defined so both the Museum and I could get interesting stuff: the whole group was given to me, and I was charged to introduce them in the hobby, so in case of need, the Museum can easily find some in captivity. All the dead specimens from the F1 were pinned, and it was decided they had to get back to the Museum's collection. I'm now starting to sell them (and will strat to sell some again in a few months), and most of the pinned animals are back to them. I also received a Blattidae from the Philippines from the Museum, here is the link (you can also scroll on the page and you'll find more topic about Schizopilia): And the pined animals, ready to get back to the MNHN collection: Best regards, Nicolas

    Lanxoblatta rudis

    Gil, I'm impressed on how much both nymphs and adults looks close to Schizopilia! I'll try to take some new pics when my nymphs get adults to show you

    Periplaneta sp. appreciation thread.

    What about Periplaneta americana "black"? I need to take better pictures of this strain...

    What makes a Princisia "Tricolor" a "Tricolor?

    normal Princisia appear black. The space between the segments might be lighter, but the general color is definitely black.

    What makes a Princisia "Tricolor" a "Tricolor?

    The diference between the "black and white" and the "tricolor" form is mainly the color on the thorax: the vestigal wings are brown/red on tricolor, darker, on the black and white. The shape of the stripes are also a bit diferent... But there are still variations in each strain.

    New Therea species could be coming to US hobby

    I'd say they were about the size of Therea regularis. Both sex were smaller. There were several specimens, all were about the same size

    ID help

    Morphna yes, but I wouldn't be sure about the species... A lot of Morphna are really close in appearance

    New Therea species could be coming to US hobby

    A few news: I visited the Paris Museum's collection and compared T. petiveriana (from the museum) to my T. berhardti. Sizes are VERY different, no exception. T. petiveriana is way smaller than what we keep!

    Eupolyphaga sinensis

    Hello, I guess it's possible, but they are not the best feeders... Slow growers, it will require a lot of space to breed them if you want to constantly have preys for your animals. They are good producers (I have a colony of 600-1000 of them), but the colony is big due to the fact I keep most of them...

    bin size selection and fine mesh

    It has been identified as Paraplecta minutissima.

    Interesting Info...

    I was planning to share it here and on a few facebook groups in a few days... That's a good thing it's already done! Thanks for sharing As a piece of information, other roaches might be identified in the near future. I'll post an update about it as soon as I have some news!

    Elliptorhina javanica Climbing Abilities

    very soft plastic may prevent evasion from a short amount of time, but when it gets older, little scratches appears on it and roaches are able to climb (event some non climbing species )

    Balta notulata

    thanks a lot! Do you breed them in the cup I can see on the pictures?
  19. Nicolas Rousseaux

    Balta notulata

    How do you exactly keep them? I've tried to breed them but it failed :/

    Vanishing Isopods?

    Eublaberus are known to be aggressive to other inverts, I wouldn't be surprised if they kill and eat is isopods, I have isopods in lost if my copies but not in Eublaberus...

    Little Kenyans

    Hey, Just digging up this (very!!!) interesant topic... Orin, I heard you find out they were Paraplecta sp., is it sure? Do you also know the species? I hope to see more roaches identified in the future, that's a shame we have so much species waiting for an ID

    New Therea species could be coming to US hobby

    Hi guys, I have both strains from Jorg in culture. An important thing to know is that both black AND yellow underwings were obviously mixed in his roaches. So, or both are from the same species, and it's just an inner species variation, or they can hybridize and in that case, botch of my colonies are just bullshit. By security, I've kept all black hindwings adults in a tank, and all yellow hindwings in an other one. I'm waiting for their babies to get adult so I'll know it has a chance to be two different species or not. Originally, all those Therea were sold as Therea petiveriana. The strain was obviously ID by Fabian Deck in Belgium who compared them with other Therea in a museum. I personnaly know him, and last time I saw him we discussed about the possibility it was not petiveriana. Indeed, this species was the more close to what we have in captivity, but he didn't made any wings comparison or anything, he was very quick to ID them and confess he might be wrong, but there were no other Therea in stock that looked like this. I had a very quick talk with Ingo Fritzsche (who described Therea bernhardti) when I met him last year and he clearly told me the other species, with yellow underwings, was maybe from the same species. No one knows at the moment, but we shouldn't be too enthusiastic about this "new species". If my colony occur to be 100% yellow hindwing, I'll send him some samples so he can confirm me if it's new or not. Note: what we have in culture is Therea bernhardti, not petiveriana. True petiveriana has hindwings longer than berhardti. When the ID mistake was spotted, Ingo described the new species but the wrong name was already very popular in the hobby. The two strains, yellow and black hindwings, are very short winged. In both case, they are definitely not Therea petiveriana Best regards, Nicolas
