Erythrina Gall Wasp

EGW_symptomsThe Erythrina Gall Wasp is an exotic pest of the Wiliwili tree (Erythrina variegata).  Common tree names include tigers claw, Indian coral tree and Wiliwili-haole.  It was first discovered in Hawaii in 2005.  Populations of Wili-Wili or Erythrina occur in Hawaii, California and Florida.  EGW completes its lifecycle in as little as 21 days.  It is a destructive, exotic pest that may kill trees in as little as two years. If trees are at risk of EGW infestation, inspect trees on a regular basis, especially the new foliage.  Look for swelling (galls) in leaf tissue and in twigs.  It is our recommendation to treat to protect trees in advance of an infestation or as soon as possible following EGW detection.


Erythrina Gall Wasp is an exotic leaf and twig galling wasp that attacks Wili-Wili trees. The developing EGW larvae induces galls in tender leaf and stem tissue. Unchecked infestations cause leaf deformation, reduction in growth, defoliation and tree death.
