Erodium moschatum is a species of flowering plant in the geranium family known by the common names musk stork's-bill and whitestem filaree.

This is a weedy annual or biennial herb which is native to much of Eurasia and North Africa but can be found on most continents where it is an introduced species.

Musk stork's-bill is an annual monoecious herb which grows as a sprawling, procumbent to erect plant up to about 60 cm long or tall, with a musky smell when bruised.

[4] Several species of insects have been recorded on musk mallow, including the midge Dasineura erodiicola, which causes galls on the flowers.

Two moths are recorded feeding on the leaves: the Setaceous Hebrew character and Thaumetopoea herculeana, as is the weevil Donus dauci and the green peach aphid.
