- Description
-
Desmodium spp., commonly known as Beggars lice is a woody trailing legume in the Fabaceae family. There are dozens of species and there is indecision in the taxonomic world in defining the genus. This plant can be used as a living mulch or green manure as they are able to improve soil fertility via nitrogen fixation. They can also be used as livestock fodder. The hairy seedpods readily cling to fur and clothing so both animals and humans unwittingly spread their seeds. They germinate readily and can become weedy.
Beggarlice are herbaceous perennials that may grow 2 to 4 feet tall. The leaves are alternate and trifoliate with hooked hairs on the underside. Flowers vary in color from white to violet. The herb produces a triangular seed that sticks like a tick.
Fire Risk: This plant has a low flammability rating.

- They make a quality food source for bobwhite, turkey, grouse, and deer. This is a larval host plant for many species of butterfly. Silver-Spotted Skipper (Epargyreus clarus) appears from May-September with three-four broods in the deep south, two broods in the east, and one brood in the north and west. Hoary Edge (Achalarus lyciades) has two broods from April-September in most of its range, one brood from June-August in the north. Northern Cloudywing (Thorybes pylades) broods from May-July in the north, earlier in the south and two broods from March-September in Texas. Southern Cloudywing (Thorybes bathyllus) which has two broods (possibly three) from June-early October in most of its range, one brood mid-June-mid-July in the north. Gray Hairstreak (Strymon melinus) has three to four flights from February-November in the south and two flights from May-September in the north. Eastern Tailed-Blue (Everes comyntas) has many broods from February-November. In the winter, its seeds serve as a food source for songbirds, quail, and small mammals.
