These are generally small moths and are sometimes known as grass moths. They have long legs and a beak like proboscis, which is covered in scales. Their forewings are triangular in shape with broader hind wings, and have a tendency to sit with their wings open and forming a distinct triangle. When at rest the front of the body is often elevated as they sit up on their long front legs with the abdomen sometime curled up over the body. This combined posture is a common characteristic of the family.

Pyralid larvae are varied in their habits and feed on a wide variety of plants and plant products including stored grain, dried fruits and tobacco. Some species are also foliage feeders and tip and stem borers of herbaceous and woody plants.
