That is very interesting. i have never witnessed a dubia roach take flight and i have 60,000+ But they do flutter with style when i throw them at my friends lol. I consider flight when they can actually control their take off and destination. such as using flight to escape. You will never see a dubia take off from the ground and travel upward more than 4". If you can capture it on video i wanna see it for the soul reason that i have never seen it before.
