Peekay you're wrong, icon looks really good as quality.
However, I suggest to make it with like 2-3 bugs, focusing on the head of one of them in, say, the down right corner and the other 2 flies behind the head, showing some wings and stuff. This way you will provide the head of an insect giving the assumption that these 2 paints behind are insects too! Plus, the wing will further prove that these figures are insects. The smoke in this icon, btw, is pretty awesome, you can add it to such an image (with the 3bugs) - this way you will give feeling and swarmness...swarmness. Hmm. Swarm. To the icon, which will complete it. You can use some green colors if you want them to look infected.
Other than that,this icon looks amazing as quality, the only problem is the focus. (btw, this version is a lot better than the old one)
