Quadrastichus
Quadrastichus is a genus of small parasitic wasps in the family Eulophidae, subfamily Tetrastichinae. The genus includes species with diverse ecological roles: some are gall-inducing pests of trees, while others are ectoparasitoids used in biological control programs. Notable species include Quadrastichus erythrinae, an invasive gall wasp that damages Erythrina (coral trees) in tropical and subtropical regions, and Q. mendeli, an obligate ectoparasitoid of the eucalyptus pest Leptocybe invasa that has been successfully established for biological control across multiple countries.
Terastia
Terastia is a genus of snout moths (Crambidae) comprising eight species distributed across tropical regions worldwide. First described by Achille Guenée in 1854 with Terastia meticulosalis as the type species, the genus is currently classified within the tribe Margaroniini. Species occur in the Neotropical, Afrotropical, and Oriental realms as well as Australasia. Caterpillars are known to feed exclusively on Erythrina species (Fabaceae), a trait shared with related genera Agathodes and Liopasia.
