Derrima stellata
pink star moth
Derrima stellata, commonly known as the pink star moth, is a small noctuid moth native to eastern North America. The species has a wingspan of 21–30 mm and exhibits bivoltine flight periods in spring and summer. It was historically notable among lepidopterists for its poorly understood life history, which was resolved in 2024 when larvae were discovered feeding on seeds of dead pinweed (Lechea species). The species is listed as a species of special concern in Connecticut, reflecting apparent rarity or habitat loss in parts of its range.
