Erythrina gall wasp
Quadrastichus erythrinae

Erythrina gall wasp (Quadrastichus erythrinae) is an insect pest of Erythrina spp.. It was first detected in Hawaii in 2005.

Like other gall-forming eulophid wasps, eggs are inserted inside young leaf and stem tissue of the ornamental Coral Tree. The wasp larvae, which develop within plant tissue, induce the formation of galls in the leaflets and petioles.
