***Macroxiphus***[1] is a small genus of [bush crickets or katydids](/source/Tettigoniidae) distributed in [Southeast Asia](/source/Southeast_Asia) and [Micronesia](/source/Micronesia). The nymphs (immature stages) of the insects [mimic ants](/source/Ant_mimicry).

## Species

Species include:[2]

- *[Macroxiphus nasicornis](/source/Macroxiphus_nasicornis)* Pictet, 1888 - [type species](/source/Type_species)
- *[Macroxiphus sumatranus](/source/Macroxiphus_sumatranus)* (Haan, 1843)

## Camouflage and mimicry

Young [instars](/source/Instar) of *Macroxiphus*, such as *[M. sumatranus](/source/Macroxiphus_sumatranus)*, have an "uncanny resemblance" to ants, extending to their black [coloration](/source/Animal_coloration), remarkably perfect antlike shape, and convincingly antlike behaviour. Their long antennae are [camouflaged](/source/Camouflage) to appear short, being black only at the base, and they are vibrated like ant antennae. Larger instars suddenly change into typical-looking [katydids](/source/Katydid), and are entirely [nocturnal](/source/Nocturnal), while the adult has bright [warning coloration](/source/Warning_coloration).[3]
