I made a video on how to get this achievement.
Basically you want to go to the Return to Hall of Heroes Plaza chapter.
Once done run down to the sky rail at the end and bring in the mosquito to your right.
If it gets destroyed then you can simply open another tear and after a few seconds you can open the mosquito again.
Rinse and repeat!
Let me know if this helps!
I hope to get more videos soon.
