Which seasonal invader is referred to as a "reflex bleeder"?

The correct choice identifies the lady beetles, commonly referred to as "reflex bleeders." This term is used because when these beetles feel threatened or are handled, they can secrete a yellowish fluid from their joints, which contains a mixture of chemicals, some of which have a strong odor. This reflex action serves as a defense mechanism, deterring potential predators.

Understanding this behavior is essential for pest management, as it helps identify the presence of these beetles and informs handling practices should they need to be removed from structures. The other seasonal invaders mentioned do not exhibit this specific behavior. Clover mites, boxelder bugs, and Asian lady beetles have different defensive strategies or characteristics and do not produce the same reflex bleeding response. Thus, the association of lady beetles with the term "reflex bleeder" reinforces their unique defensive adaptation among common pests.
