Mulsantina picta

(Randall, 1838)

Painted Lady Beetle, Pine Lady Beetle

Mulsantina picta is a small lady beetle native to North America, commonly found in pine forest across the United States and southern Canada. The is a specialized of aphids and adelgids associated with conifers. measure 3.3–5.3 mm in length and exhibit variable elytral patterning. The species has been observed to dominate in older pine stands despite low densities in these habitats.

Identification

Distinguished from similar lady beetles by the more constant pronotal markings, which remain recognizable even when elytral markings are reduced or absent. The small size and association with conifer provide additional context. Separation from other Mulsantina requires examination of specific pattern elements on the pronotum and .
