answer:Cockroaches do indeed fly. They’re not regular flyers, and can’t fly for as long as other flying insects, but they can. Of course there are many different kinds of cockroaches, all belonging to the order of blattaria, and maybe some can fly better than others, but as far as I know, most types of cockroaches have wings (in their adult stage only) and have the ability to fly. (and glide, rather, when hopping off a high source) If that’s not what your insect was, then I don’t know, maybe one of these? (although I’m guessing if it was that thing you would have mentioned the huge front legs)
