I finally took the time to photograph some of my Dipteretrum hanstroemi roaches.
I had to take some precautions, because of their skittishness and good climbing capacity, but I managed!
It's still not clear to me what 'pest' capabilities they posses. Do do not fare well at lower temperatures (< 20C / 68F), but can do quite well in dryer habitats. They can climb well, and have a high reproduction rate. So far I have managed to keep them contained to their enclosure...
Video will follow soon!
