Which type of grain beetle does not have the ability to fly?

The Saw-Toothed Grain Beetle is distinctive in its inability to fly, a trait that sets it apart from several other grain pests. This small beetle has a flattened body and is characterized by the six saw-tooth projections along the edges of its thorax, which give it its name. Unlike the Merchant Grain Beetle and the Rice Weevil, both of which are capable of flight, the Saw-Toothed Grain Beetle relies on crawling to navigate and find food sources. Understanding the characteristics of these pests is crucial for effective management and control in grain storage environments, as it allows for targeted strategies that account for their behavioral tendencies.
