Chauliognathus pensylvanicus

Closeup of two beetles on yellow goldenrod flowers. The beetles have long bodies with narrow wing covers, which are yellow-orange in color except for a dark oval covering the bottom third of each wing cover.

With the continuing growth of community-driven, digital nature observations on platforms like iNaturalist, entomologists and other scientists are tapping into that store of knowledge to make new discoveries. A new study shows the potential for photo observations to answer species-specific behavior and ecological questions, such as the flower preferences among two soldier-beetle species, Chauliognathus marginatus and Chauliognathus pensylvanicus (shown here).
