What do cave or camel crickets primarily consume?

Cave or camel crickets are primarily known for their diet that consists of organic matter found in their environment. This includes a variety of decomposing materials, mainly plant debris, along with paper products. While they might occasionally nibble on starchy foods or fabrics, their primary consumption focuses more on materials rich in cellulose.

The first choice, which is about starchy foods and fabrics, mischaracterizes their diet. These crickets do not have a specific preference for starchy foods but rather tend to feed on decomposing vegetation, which provides them with the nutrients they require.

The other options mention fabric and products made from leather and paper, which may attract them if they are in deteriorating condition. However, it's the plant debris and organic materials that constitute the majority of their diet in their natural habitats. Therefore, recognizing their ecological role helps clarify that they are less about consumption of contemporary food items and more about breaking down the remains of organic tissues in the environment.
