August 2005. The gall wasp was observed in the Philippines for the first time in 2005 infesting E varigata, locally known as dapdap.
November 2006. Q erythrinae is spreading rapidly throughout southeast Asia and the Pacific, causing severe damage and even death of various species of Erythrina (coral) trees. In Hawaii, besides working on the biological control of the wasp, scientists are comparing the DNA of specimens from throughout Asia and the Pacific with those of potential source populations from West, East, and South Africa.
The gall wasp was described in the following paper:
