What is a characteristic feature of adult bed bugs?

Adult bed bugs are characterized by having a short, broad head and being wingless. This physical feature is significant as it differentiates them from some other insects that might have similar body shapes but possess wings. Bed bugs belong to the Cimicidae family, and their wingless nature is a critical aspect of their biology and behavior; they do not fly but rather crawl swiftly to find hosts for feeding.

Additionally, their broad head design plays a role in how they feed, as it allows for a stronger grasp when they pierce the skin of their hosts to draw blood. This feeding behavior is integral to their life cycle and is one of the reasons why they are considered pests in human dwellings. Knowing these characteristics helps in correctly identifying bed bugs and understanding their behavior in relation to infestation and control measures.
