Aularches miliaris is a grasshopper species of the monotypic genus Aularches, belonging to the family Pyrgomorphidae. A native of South and Southeast Asia, the bright warning colours of this fairly large grasshopper keep away predators and their defense when disturbed includes the ejection of a toxic foam.

Pyrgomorphidae is a family of grasshoppers in the order Orthoptera; it is the only family in the superfamily Pyrgomorphoidea. Pyrgomorphidae is found worldwide in tropical and warm temperate regions, but the vast majority of the family's approximately 500 species are from Africa, Asia and Australia. Their name is probably derived from pyrgos meaning "tower": a reference to the form (morph) of the head in the type genus Pyrgomorpha and other genera.
