With ~35,000 described spp. in >2100 genera and up to 60,000 estimated spp. worldwide and ca. 1900 valid species and subspecies in ~220 genera in our area, this is one of the five largest beetle families and second largest (after Curculiondiae) among phytophagous beetle families(1)(2); 10 out of 12 subfamilies are represented in NA(3)

Chrysomelids are phytophagous and are among the most diverse and conspicuous insect families on plants. The adults feed on living plant material, usually consuming leaves or sometimes various flower parts including pollen. Many chrysomelid larvae feed on leaves, but a great number are subterranean, attacking roots and underground stems.(1)
Most NA species are probably univoltine(1)
Most are fairly specific in host preferences, being either monophagous or more commonly oligophagous(1)(7)
Life Cycle
most Nearctic spp. overwinter as adults; larvae have a wide variety of life histories(1)
A fair number of leaf beetles are of economic importance; some are used to control invasive weeds(1)
