Blattodea313 Posted March 1, 2014 Share Posted March 1, 2014 I like the nymphs better than the adults They look like prehistoric trilobites. Quote Link to comment Share on other sites More sharing options...
MrCrackerpants Posted March 1, 2014 Share Posted March 1, 2014 My Blaberus craniifer do not look like this at all...mine look like this... http://i135.photobucket.com/albums/q152/Matt_Kaplinsky/Bug%20Things/Blaberuscraniifer.jpg Quote Link to comment Share on other sites More sharing options...
Nicolas Rousseaux Posted March 1, 2014 Author Share Posted March 1, 2014 We have two forms in the european hobby, I don't know if it's the case in the US. We have that light form and the black one too, I'll post pictures of those ones next week Quote Link to comment Share on other sites More sharing options...

No we just have the dark form but have two different strains... the "Orin McMonigle" and the "University of California, Riverside" Quote Link to comment Share on other sites More sharing options...
Chinese insect fans Posted March 2, 2014 Share Posted March 2, 2014 I prefer the nymphs to the adults. But I don't know why. Quote Link to comment Share on other sites More sharing options...
Blattodea313 Posted March 2, 2014 Share Posted March 2, 2014 I prefer the nymphs to the adults. But I don't know why. I like the nymphs better because of their coloration. The yellow and the brown go good together. Quote Link to comment Share on other sites More sharing options...
MrCrackerpants Posted March 2, 2014 Share Posted March 2, 2014 Kyle at roachcrossing.com is saying "The tell-tale mark of the death's head roach is the jack-o-lantern face on the pronotum, as well the jet-black wings." He also says "the death's head roach is often (unbelievably) mistaken for several other species..." Are you sure this is Blaberus craniifer?

Nicolas Rousseaux Posted March 2, 2014 Author Share Posted March 2, 2014 They are from a quiet reliable breeder, so I'm quiet sure they are. As far as I know, the holotype for this species is brown winged, not black, but specimens are highly variable. We talked about it with several other hobbyist, loads of us think that they might be the same species (very difficult to say with this genus), but from different area Quote Link to comment Share on other sites More sharing options...

We talked about it with several other hobbyist, loads of us think that they might be the same species (very difficult to say with this genus), but from different area OK I am always willing to learn new science. Maybe a few others (e.g., Kyle and Orin) and chime in on this to further add to this interesting discussion . Quote Link to comment Share on other sites More sharing options...
Forcep Posted March 3, 2014 Share Posted March 3, 2014 Love the picture of the nymph; my giant cave and peppered roach nymphs are always covered by dirt and hard to take a good picture... Quote Link to comment Share on other sites More sharing options...
vfox Posted March 9, 2014 Share Posted March 9, 2014 A bunch of us had a long round and round discussion on this species. According to Kyle the "holotype" of this species was a nymph so there isn't a way to prove which is the true holotype. The more likely explanation is that they are two separate but closely related species, the black winged being a very distinct species. The brown wing is either a poorly classified but closely related species or a hybrid that was mistakenly introduced early on into the hobby and laboratories for test animals.

Keith Posted March 9, 2014 Share Posted March 9, 2014 IMO the brown ones are much hardier and grow faster. I've raised both and that's the observation I made. The black ones can fly better though. Quote Link to comment Share on other sites More sharing options...
