We dust the crickets prior to placing them in the feeding cups. We hang the cup out of the path of the mister so that the crickets don't get wet (which is on the door of the cage).
The cups we use are not entirely transparent. It is a soup container. The chameleon can see thru it just enough to know that there is food in there, yet also know that his tongue can't shoot thru it.
In regards to hanging the cup, it will depend on your cage. We lined the inside of the cage with plastic green mesh w/ very large holes. This mesh also helps them climb, and prevents them from losing their nails. The cup hangs from the green mesh.
Notice in the bottom pic how the chameleon is holding onto the mesh, versus using his nails in the screen. Underneath him, you will see how the feeding cup is hung from the mesh.
