Ant crickets and other myrmecophiles

Ant crickets (genus Myrmecophilus Berthold, 1827) are small orthoptera, which are known to live as kleptoparasites in the nests of ants. They are known to feed on food resources in the ant nest and induce their hosts to regurgitate liquid food. Based on today's knowledge
some species reproduce parthenogenetically, e. g. Myrmecophilus acervorum (Panzer, [1799]), but most species reproduce sexually.
