The leaf-mining fly Hydrellia lagarosiphon (Diptera: Ephydridae) is being considered as a classical biological control agent in New Zealand and Ireland against the invasive species Lagarosiphon major, alien species of Union concern under EU Regulation 1143/2014. 

Under laboratory conditions, larvae of H. lagarosiphon showed a substantial impact on L. major and can halt plant growth, with a potential to become an effective biological control agent.
