Death's Head Roaches (Blaberus craniifer hybrids)

Post  VenomVyxen on Wed May 02, 2012 2:00 pm

Gahh, it took me forever (a couple hours) to determine they were even hyrbids. This is the best conclusion I can draw, short of dissecting male genitalia (which I don't mind doing, if I actually had other dissections to compare to). Don't ask me what strain they are, I have no idea, though I would not object to a Blaberus-wise forum member educating me. I am convinced they are not pure discoids, based on appearance.

THEY HAVE FINALLY REPRODUCED! Yes. They're all still in first instar, and I can't wait for another batch of offspring.

Does anyone else rear Death's Heads or False Death's Heads here?

And, so this is not entirely pointless, here's a photo I took of one caught in the act of molting:

Ive never bred Blaberus discoidalis what would the shell to meat ratio be on these guys im thinking maybe the same as dubia? these guys actually breed faster than a true Blaberus discoidalis quite interesting or im really a dork lmao

As far as the ratio is concerned, I am not sure exactly. The adults get about 3 inches long, so they do get up there in size and the abdomens are plump. If I were to compare them to a hisser, the hisser is definitely more heavy bodied, but the shells on these seem much thinner and more easily digested. The males and females have wings, but they're thin and not much to worry about (probably good ruffage lol). The big plus on these guys is they can't climb as easily as hissers can. I've had problems with hisser nymphs escaping in the past, but the death's head nymphs just scurry helplessy at the bottom of the tub.
I haven't raised true Blaberus, so I could not compare first hand, but that seems to be a firm opinion.
Haha, you're not a dork! And if you are, then you're in good company! I find inverts fascinating and am fond of the larger species of exotic roaches. I've raised Dubias and Hissers in the past, but these are new to me and the amount of information out there on lineage and strains of these is blowing my mind!

LOL...I've fed dubia,Turks and lobsters and I believe none of them have as high an exoskeleton-to-meat ratio as crickets,plus not so noisy constant chirping use to drive me insane..I have to be honest when i first got my dubia i was so scared of them lol... every time they moved i would jump 10 feet in the air.

Great! Just great, I have to pick the one topic that I am so not into BUGS! GAH. Actually to be honest feeder insects don't bother me its the Solfugids that try to eat me. I have never been a big fan of roaches for feeders. I understand less noise etc but as far as nutritional content never saw a real advantage that someone could show me on paper so to speak. You ladies got any information on that? Have there been studies done or are we all just guessing?

Ive just done a little researching and I did actually find a sort of paper,However wont post as i don't have permission to do so, i well send it directly too you,From what I understand, roaches in general are better than crickets not so much for their 'meat to shell ratio', but for their calcium to phosphorus ratio. Roaches have more calcium than crickets, and much less phosphorus...

Variety is is the spice of life. I don't object to feeding crickets to herps (that's what I'm doing now while I wait for my colony to grow) but giving your insectivores different inverts to eat should be nothing but beneficial. Roaches are just my preferred staple.
From a personal standpoint, I feel more like I've given my lizards/Ts a more savory meal when I feed them roaches that I've gutloaded. Also, when I look at photos online, I tend to notice that captive tarantulas that are fed roaches are often bigger/healthier looking. That -is- simply my own personal observation though (I know there is no way for me to prove they are healthier through a photo online).
I haven't found any papers, personally, but I wouldn't mind being linked to one. Smile
