LyleL Posted August 26, 2008 Share Posted August 26, 2008 Can anyone give me a definitive description as to how to tell B. giganteus nymphs from B. fusca, etc. Lyle Quote Link to comment Share on other sites More sharing options...
Zephyr Posted August 27, 2008 Share Posted August 27, 2008 I've noticed a only a few subtle difference, such as B. giganteus in the last instar would be much larger than B. fusca. Also, fusca nymphs appear to have much more colorful markings. Quote Link to comment Share on other sites More sharing options...
Allpet Roaches Posted August 27, 2008 Share Posted August 27, 2008 Early instars may be difficult to tell apart but B.giganteus nymphs are mostly maroon and B.fusca are mostly black. Also, of course, B. giganteus subadult nymphs are twice as big. Quote Link to comment Share on other sites More sharing options...
