I have a clam that has modified its foot to make a flat, net-like structure to catch insects often shaped like a leaf. I wanted to know where this hit in terms of feasibility or if there were any examples of an appendage like this in nature.

It lives in an extremely humid canopy that is full of water pockets and it has adapted to prolonged periods out of water.

Edit: The muscular net would appear much like a leaf with criss-crossing portions an primary veins and would.be covered in a mucus/secretion to attract and trap insects.
