Alticini
The flea beetle is any small, jumping beetle of the leaf beetle family (Chrysomelidae) that is part of the tribe Alticini, which is part of the subfamily Galerucinae. Historically the flea beetles were classified as their own subfamily. 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). Description and ecology The adults are very small to moderately sized Chrysomelidae (i.e. among beetles in general they are on the smallish side). They are similar to other leaf beetles, but characteristically have the hindleg femora greatly enlarged. These enlarged femora allow for the sprin ...

Galerucinae
The Galerucinae are a large subfamily of the leaf beetles (Chrysomelidae), containing about 15,000 species in more than 1000 genera, of which about 500 genera and about 8000 species make up the flea beetle tribe Alticini. The division into tribes is more a matter of tradition than based on modern research. Some genera, for example '' Yingaresca'', are better considered ''incertae sedis'' due to a general lack of knowledge. And while a good case can be made for some tribes – namely the Alticini and Galerucini – being all but monophyletic even in their traditional delimitation, others, such as Luperini, appear to be just paraphyletic assemblages of primitive and more basal genera. Some classifications of Galerucinae include just two tribes, Alticini and Galerucini, and treat all of the tribes of Galerucinae ''sensu stricto'' (Decarthrocerini, Galerucini, Hylaspini, Luperini, Metacyclini and Oidini) as subtribes of Galerucini.
