MrCrackerpants Posted October 27, 2012 Share Posted October 27, 2012 Is it normal for Blaberus giganteus to have a pronotum with just the smile similar to the Death's Head Cockroach on it or is it normally just a large black dot? Quote Link to comment Share on other sites More sharing options...
Zephyr Posted October 27, 2012 Share Posted October 27, 2012 Could you post a picture? From what it sounds like you have a giganteus with no black on the pronotum! Quote Link to comment Share on other sites More sharing options...
MrCrackerpants Posted October 27, 2012 Author Share Posted October 27, 2012 Could you post a picture? From what it sounds like you have a giganteus with no black on the pronotum! Thanks Kyle. I got them from Peter. Sorry about the description because it sounds that way! The pronotum is a large black dot except for a red smiley face minus the eyes and nose. It just has the mouth. It this normal? Most don't have this but a few do. I can't post a picture now because the roaches are not with me. Probably not a big deal. Just thought I would see if it was.

Zephyr Posted October 27, 2012 Share Posted October 27, 2012 Well it doesn't sound problematic but it does sound super cool! Let me know when you get pics! Quote Link to comment Share on other sites More sharing options...

blatta70 Posted October 28, 2012 Share Posted October 28, 2012 I have seen B. giganteus populations that have the half-faced "grin" as well. I had some that I received from Barney at Hatari Invertebrates. Many populations lack the pronotal markings all together while some have a blended ratio between the two. There's a possibility that the two types may have originated from different regions in South America. The "grin" is likely a dominant trait since it is strongly exhibited by most members within the Giganteus species complex. Quote Link to comment Share on other sites More sharing options...

Zephyr Posted November 1, 2012 Share Posted November 1, 2012 So... Ever get pics of them? I'm dying to see what they look like! Quote Link to comment Share on other sites More sharing options...
MrCrackerpants Posted November 2, 2012 Author Share Posted November 2, 2012 So... Ever get pics of them? I'm dying to see what they look like! Oh, sorry. I am so swamped with work. I am going to put it on the calendar so I remember to do it. I hope you are not disappointed. It is just a normal Blaberus giganteus with a black pronotum dot that has a little red smile in the middle. Quote Link to comment Share on other sites More sharing options...
Allpet Roaches Posted November 2, 2012 Share Posted November 2, 2012 I'd bet you two have the same stock. I see it as more of three spots but it does vary. Quote Link to comment Share on other sites More sharing options...

Some of them are like that too. I took pictures today. I will post them ASAP. Quote Link to comment Share on other sites More sharing options...
MrCrackerpants Posted November 2, 2012 Author Share Posted November 2, 2012 Here you go. These are all Blaberus giganteus. I bought the stock as 3 nymphs from Peter at www.bugsincyberspace.com in March, 2011. In the picture to the left you can see the smile. In the middle picture you can see the smile, the red dot and one with no red mark of any kind. On the right picture you can see the smile and a red dot (the flash obscured the red). As I said before, I'm not sure that the "smile" on a Blaberus giganteus is really that big of a deal. Quote Link to comment Share on other sites More sharing options...

They are really pretty. They look like Discoid, exept the body is wider. Quote Link to comment Share on other sites More sharing options...
