I've been trying to determine if there is any canon or other definitive source that indicates the approximate size of the worker and warrior-caste of "Bugs", in the novel Starship Troopers.
There is a brief description of a captured "brain bug" in the arachnid tunnels beneath the surface of planet Shiloh during Operation Royalty. I believe that arachnid was small enough that a lone trooper was able to carry it. I do not recall any descriptions of the size of worker and warrior arachnids in the novel, however. I've seen various depictions of them in cover art of the novel, including one version I recall where the arachnids were depicted as enormous creatures several stories tall. But I have yet to find anything concrete/definitive on the size.
Are there any canon references that might determine there size (including any passages in the novel I may not be recalling)?
