N. cinerea has a scary reputation, but the truth of the matter (at least based on my personal experiences thus far) is they're a GREAT feeder roach for Chameleons. That said, I feel compelled to give my $0.02 regarding some of the more common complaints.
- Yes, N. cinerea can climb vertical glass and plastic surfaces... However, so can B. dubia nymphs. Ultimately, both species require the same preventative countermeasures (i.e. a secure enclosure with a climb-proof barrier).
- Yes, N. cinerea are fast movers... But it's not like B. dubia are 'slow' by comparison. Plus, N. cinerea have wings; which happen to be great for grabbing them securely with forceps. Anyone that's tried to grab a B. dubia can attest to the fact that they can be difficult to grab (without squishing).
- No, N. cinerea don't fly.
Now, in terms of a head-to-head comparison (B. dubia vs N. cinerea) these are just a few random points that came to mind:
Odor - I have large colonies of both B. dubia and N. cinerea and I honestly don't notice an odor from either enclosure.
Reproductive rates - This one isn't even close... B. dubia reproduce quickly, but N. cinerea reproduce at biblical plague proportions; which is actually a good thing because a comparatively smaller colony can effectively feed a Chameleon.
Harvesting feeders - In my opinion, it's much easier to feed off full-size N. cinerea adults than it is to look for appropriately sized B. dubia nymphs. Plus, N. cinerea have wings; which makes them so much easier to grab... Not to mention hand feed.
What I don't know is how N. cinerea stacks up to B. dubia in terms of nutritional value... If anyone else knows please chime in.
