Which feature is characteristic of winter stoneflies?

Winter stoneflies are known for their light brown or cream coloration, which helps them blend into their environment during the colder months. This lighter coloration serves as a form of camouflage against the snow and ice that are common in their habitats. Their ability to survive in cold water and thrive in winter conditions is a distinctive characteristic of this group of insects.

In contrast to the specific light brown or cream coloration, options like dark coloration, bright yellow shells, and all black body segments do not accurately represent the typical appearance of winter stoneflies. These insects have evolved to be less visible to predators by having colors that match their surroundings during wintertime.
