Cecidomyidae is a family of insects commonly known as gall midges. They are small, fly-like creatures that feed mainly on plant tissues. While the term Cecidomyidae is widely used, there are a number of other synonyms for the word that can be used interchangeably. Some of these include the gnat midges, the midge flies, the leaf-rolling midges, and the Hessian flies. In biology, it is common for scientists to use different names for the same organisms. This can be confusing for those not familiar with the specific terminology, but it is important for researchers to use the most accurate name possible to ensure effective communication and understanding.
