Hyperaspis bensonica
Casey, 1908
Hyperaspis bensonica is a small lady beetle in the Coccinellidae native to southwestern North America. measure 1.90–2.90 mm and exhibit distinctive coloration: males have yellow lateral and pronotal margins, and the bear a discal spot and lateral vitta. Like other members of the Hyperaspis, this is a of scale insects. The larvae produce waxy secretions that serve as protective camouflage, causing them to be frequently mistaken for mealybugs or scale insects.

Identification
distinguished from other Hyperaspis by specific spot and vitta pattern on combined with male pronotal coloration. Larvae covered in white waxy secretion, resembling mealybugs; distinguishable by faster movement when disturbed and predatory near insect colonies.
Habitat
Associated with woody plants supporting insect ; found in arid and semi-arid regions of the southwestern United States.
Distribution
Recorded from Arizona, California, and Texas.
Diet
of scale insects (Coccoidea), including and stages.
Life Cycle
Complete with , larval, pupal, and stages. Larvae develop through autumn, pupate, and emerge as adults. Adults overwinter in protected locations beneath bark or in leaf litter, returning to plants in spring to reproduce.
Behavior
Larvae produce waxy secretions from lateral glands that reduce by ants and other enemies. and larvae actively forage on insect colonies. Larvae move quickly when disturbed, unlike the sedentary mealybugs they resemble.
Ecological Role
agent of scale insects; contributes to natural suppression of on woody plants.
Human Relevance
Beneficial insect for garden and landscape pest management. Frequently misidentified and killed due to larval resemblance to pests. Important natural enemy of such as crapemyrtle bark scale (Acanthococcus lagerstroemiae).

Conservation concern
threatened by broad-spectrum use targeting scale insects; educational efforts needed to prevent misidentification and unnecessary mortality of larvae
