This Drosophila???, I have met in my lab. I have been keeping them for a while. I have no answer for my previous question so far. I here add new pics and a video. It moves in a hurry, like a cockroach unlike Drosophila melanogaster that moves and files gently. I also added Drosophila melanogaster (the one with red eye on the left in pic.) from my lab stock with this my alien speies for a comparison. Drosophila melanogaster and this alien whenever meets they behave like fighting dogs.Thanks.
