Alticini
Extracted from the Wikipedia article Flea beetle.
Traditionally, the Alticini were separated from other Galerucinae by the presence of jumping hind legs, characterised by enlarged femora containing a spring structure allowing the flea beetles to jump. Recent phylogenetic studies suggest that jumping hind legs evolved multiple times in the Galerucinae, rather than once, and that several genera should be transferred between Alticini and Galerucinae sensu stricto (or Galerucini in some classifications).
