happy1892 Posted December 23, 2013 Share Posted December 23, 2013 Is it true that Blaberus craniifer have to have black wings to be B. craniifer? And that the ones that are more like the other species of Blaberus with brown wings with black blotches are hybrids or a different species?

RomanBuck Posted December 23, 2013 Share Posted December 23, 2013 well the ones i am getting are all black wings and she said that they are B Craniifer. i think the ones you talk about are the hybribs. Not positive though. Quote Link to comment Share on other sites More sharing options...

Nicolas Rousseaux Posted December 23, 2013 Share Posted December 23, 2013 Both are actually Blaberus craniifer, but it is not kwnon if it's a selective breeding or a different local. Anyway, beware about hybrids, they exist and need to be avoided Quote Link to comment Share on other sites More sharing options...
vfox Posted December 23, 2013 Share Posted December 23, 2013 After having this discussion on a Facebook group the other day with folks from the US and Europe it seems that there is some much needed research into the holotype to be done. But the consensus currently is that they are both Blaberus craniifer but the black winged animal being from the Caribbean and southern Florida while the brown winged animal is from Central and South America. That being said, I feel like these two should never have been named the same species. If the holotype of Blaberus craniifer is the brown winged cockroach then the black winged cockroach should be renamed. They are able to crossbreed because the male genitalia is the same shape. For some reason this ability to hybridize has everyone convinced they are the same species... Which tends to ignore all the other Blaberus that can hybridize. Not to mention the two animals have differently shaped bodies, coloration, size, and behavior. But hey, what do I know... Quote Link to comment Share on other sites More sharing options...

To me, there is no differences other than one has different genes. If they get out into the wild they mix with other species and those other species die out. Also often hybrids are not healthy but sometimes hybrids are stronger (by stronger I mean better in some way). Quote Link to comment Share on other sites More sharing options...
Nicolas Rousseaux Posted December 23, 2013 Share Posted December 23, 2013 escape in the wild and often sold as pure line... You get hybrids, you sell hybrids, and one moment or another, there is that stupid guy who sell your hybrids as pure line and they get mixed to pure lineage... and the whole stock is hybrided Quote Link to comment Share on other sites More sharing options...
RomanBuck Posted December 25, 2013 Share Posted December 25, 2013 The weaker part sounds not too good, the lineage part I understand BUT if the hybrids have different markings then shouldn't they be able to tell? Obviously if your buying online your not but if it's in person then you should be able to tell the difference. If any of that makes sense Quote Link to comment Share on other sites More sharing options...
Nicolas Rousseaux Posted December 25, 2013 Share Posted December 25, 2013 the diferences are actually more complicated, that"s small details because marquing can be different within the same species :/ Quote Link to comment Share on other sites More sharing options...

Obviously if your buying online your not but if it's in person then you should be able to tell the difference. If any of that makes sense There is not just crosses of half and half of each kind which would probably be easy to tell apart from one of those pure species. A roach could maybe have a very little of another species and that still is a hybrid right? And because they have so little of the other species they might look just like the pure ones.

happy1892 Posted December 31, 2013 Author Share Posted December 31, 2013 You do not mean that the whole adult German Roach is black but that they have a black belly or something?? Quote Link to comment Share on other sites More sharing options...
vfox Posted December 31, 2013 Share Posted December 31, 2013 There are a couple breeders that have strains of almost completely black German cockroaches. I hope to get some in the next few months when the weather improves. I don't care for regular ones but the black ones for some reason don't worry me as much, haha.

Do you mean they remain dark or really black? My younger German Roach nymphs had some black or dark brown on the sides and light brown in the middle.

vfox Posted January 1, 2014 Share Posted January 1, 2014 Do you mean they remain dark or really black? My younger German Roach nymphs had some black or dark brown on the sides and light brown in the middle. Completely jet black through all stages of development.
