Cicindelidae (Tiger Beetles) are currently classified within which family?

• A. Carabidae (Ground Beetles)
• B. Dytiscidae (Predaceous Diving Beetles)
• C. Hydrophilidae (Water Scavenger Beetles)
• D. Silphidae (Carrion Beetles)

Answer: (A)

The main idea here is how tiger beetles are placed in a larger beetle family based on shared traits and relationships. Tiger beetles are considered part of the ground beetle family, Carabidae, typically treated as the subfamily Cicindelinae within that family. This placement reflects their anatomy and lifestyle: they are fast, predatory beetles with strong mandibles and legs built for running, and their larval life also fits the general ground-beetle pattern of predation and burrow-associated ambush behavior. Modern classifications, including many morphological and molecular studies, support grouping Cicindelinae with Carabidae rather than treating tiger beetles as a separate family. In contrast, the other families listed are associated with different ecologies: diving beetles (Dytiscidae) are aquatic predators, water scavenger beetles (Hydrophilidae) are predominantly aquatic or semi-aquatic scavengers, and carrion beetles (Silphidae) typically feed on decaying animal matter. Tiger beetles don’t share those aquatic or carrion-focused traits, which is why Carabidae is the fitting family.
