I've once spent a good 5 minutes chasing a flying roach around the living room. It's not a particularly good flyer (e.g. compared to a housefly) although being able to outsmart me, it doesn't corner well. I think on the ground they are faster. But generally they do seem to fly less than I would did I have the ability. 

God! You guys are really hitting it really bad! I know everyone's waiting for school to reopen and it's kind of boring. But cockroaches? 

Cockroaches can fly like chickens. Badly.
Although, I swore I once saw one flying outside the 17th floor of a scyscraper.

I would imagine it's to do with energy efficiency.

They probably use up their energy store quicker if they fly.

a colleague related one afternoon how he was attacked by a flying cockroach in the shower. 

There are not many things that i dislike, but the thought of a large flying insect made me take fast showers for weeks after 

they are smart, vengeful, and can communicate with each other.  go sit down at a little run-down outside bar in Ermita, on Manila Bay and squash a few big ones on the ground; no shortage of available victims lol. then watch what happens. Swarms of them will 'dive-bomb' you.  super creepy!  but fascinating too....  

they fly good enuf, might not be on par with a bird, but a hell of a lot better than I bet most people would suspect~

you guys are creepy.  cockroaches? really?  But I do have my way to drive them away from my department. Onion.

I often envision, I am snake. Especially in the morning, when I must stand up, and move out of my bed.....ssssshhhhhsssssshhhhsssswiss, and here I am! Much more convenient than walk!
