Explanation of Names
Lixinae Schönherr 1823
Numbers
3 tribes (one non-native to NA), with ~110 spp. (of which ~70 Lixus spp.) in 11 genera in our area(1), ~1,500 spp. worldwide(2)(3)
Identification
key to New World genera in(2)
Range
worldwide, much more diverse in drier regions of the Old World
Habitat
from mesic to very arid; Lixini are usually associated with more mesic habitats, whereas most traditional Cleonini are found in arid habitats(2)
Food
hosts include a wide range of herbs and or shrubs, most notably Chenopodiaceae, Compositae, Leguminosae, Rosaceae, Cruciferae and Polygonaceae; larvae of most spp. mine stems or roots, but some (e.g., Rhinocyllus, Larinus, Microlarinus) feed in flower heads or on seeds(2)
Remarks
Members of several genera have been introduced to control weeds, esp. in rangeland of w. NA(1)
