I think they are blaberus giganteus or fusca

I'm kind of fond of them myself, though I wouldn't want an infestation in my home!

Emma, their hemolymph is more of a transparent pale yellow than it is white, but they have a large amount of white fat (called the fat body, which functions much like a liver). I had to dissect one of these cockroaches in an entomology lab, it was hard to find the organs because of all the fat in there.

Did you know that there blood is white? We had to dissect this as part of our science curriculum.

Poor roaches really get bad press. All because of a couple of pestish species.

these are huge! I have the biggest phobia on cockroaches (that began after watching men in black 1) and these guys would just freak me out.

Glad I don't have these in my home. My first thought on seeing them - "Darth Vader" of the roaches. ;)

They are recyclers of plant and animal detritus.

Fascinating creatures. I presume they live on plant detritus.
