I created a bug with two different layers for the wings and added it to after effects, I placed the anchor point of the wings on top of the body so they connect properly. I made the asset into 3d and moved it away from the background and moved it forwards. I rotated the wings  on the y axis using 4 keyframes. I made sure the keyframes were close together to get quick movement. I added a background of a lamp to the composition to show how I would use this composition.

WWW: I managed to get it moving, I could use this for having a swarm of flies buzzing around a pile of trash

EBI: when making the composition, fix the anchor points so that it works better.
