True or False: Cover mites leave a red streak when smashed even though they do not suck blood.

Cover mites are part of the larger family of mites, which are arachnids that can be found in various environments, including those inhabited by plants and animals. When crushed, some species of mites can exhibit a reddish streak due to the presence of colored pigments in their bodies, not because they suck blood. The red color can be attributed to carotenoid pigments or other natural pigments that may be present in their body tissues.

This phenomenon is observed across certain mite species, aligning with the statement in the question. Therefore, the assertion that cover mites leave a red streak when crushed is accurate, given that it is a characteristic of certain mite species, including cover mites. This observation is pertinent in the context of pest control, as recognizing these signs may aid in the identification of pests and in making informed control decisions.
