Numbers
30 species in 3 genera in North America listed in Pohl, et al. 2016 provisional checklist(1)
Size
Less than 3 mm. (2)
Identification
Adult - typically have iridescent, metallic-appearing scaling. Eyes are small as in other diurnal microlepidoptera. (2)
Larva - flattened, usually legless. (2)
Food
Species are host specific, using at least 17 families of angiosperms. (2)
Life Cycle
Last instar larvae construct a portable case by cutting disks from the upper and lower epidermis and joining them with silk, the reason for the commom name "shield bearers." The abandoned mines, with their distinctive "shot holes" are characteristic. (2)
