Hyperaspis dobzhanskyi
Gordon, 1985
Dobzhansky's lady beetle
Hyperaspis dobzhanskyi is a small lady beetle in the Coccinellidae, known from Arizona in the southwestern United States. measure approximately 2.45 mm in length. The species belongs to a whose larvae are notable for producing waxy secretions that camouflage them among scale insects, their primary prey. Like other Hyperaspis species, it likely serves as a agent of insect pests.

Identification
Distinguished from the similar Hyperaspis rotunda by the spot on the , which nearly reaches the elytral in H. dobzhanskyi. Larvae may be distinguished from mealybugs by their more rapid movement when disturbed; mealybugs tend to remain stationary or move slowly.
Appearance
reach a length of about 2.45 mm. The color pattern is similar to that of Hyperaspis rotunda, but the spot on the nearly reaches the elytral . Based on characteristics, larvae are covered in white waxy secretions produced from glands along their sides, making them resemble mealybugs or scale insects.
Distribution
Known from Arizona, United States. Distribution within North America appears limited based on current records.
Diet
As a member of Hyperaspis, larvae and are predatory on scale insects (Coccidae) and their . Specific prey records for H. dobzhanskyi are not documented, but related feed on crapemyrtle bark scale, tuliptree scale, and other soft scales.
Life Cycle
Complete with , larval, pupal, and stages. Based on patterns: larvae develop through multiple instars while feeding on scale insects, produce waxy secretions for protection, 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 are cryptic that move among insect colonies. When disturbed, larvae move more rapidly than their mealybug prey. actively search for scale insect . Both life stages are vulnerable to misidentification and accidental destruction due to their resemblance to pests.
Ecological Role
of scale insects; likely contributes to of in native . May help suppress pest scale on native and ornamental plants.
Human Relevance
Potential value as a native agent of scale insects such as crapemyrtle bark scale. Frequently misidentified and killed due to larval resemblance to mealybug pests. Conservation of this and related Hyperaspis supports programs.

- Mealybugs (Pseudococcidae)Larvae superficially resemble mealybugs due to white waxy coating; distinguished by faster movement when disturbed
Misconceptions
Larvae are commonly mistaken for mealybugs or other pest insects due to their white waxy appearance, leading to unnecessary applications that kill these beneficial .
