Alticinae, now treated as a tribe (Alticini)(1).
Explanation of Names
Galerucinae Latreille 1802
By far the largest leaf beetle subfamily, with 13,000 to 15,000 described spp. in >1000 genera of 7 tribes worldwide and ca. 700 spp. in 90 genera of 4 tribes in our area; the flea beetles (Alticini) account for over 60% of the diversity(1)(2).
Worldwide and throughout NA
Most of the galerucines feed on dicots, however some genera may have adapted to monocots. Adults generally feed on pollen and also fresh leaves of their host plants, and the larvae feed on their roots. Many species feed on wild plants, trees and bushes, and many are polyphagous
Some are serious agricultural pests, causing damage directly by plant feeding or indirectly by transmitting viruses. Some species have been used in the biological control of weeds.
