July 2006. Caterpillars have recently defoliated most of the Vitex trees on Guam. The moth has a body length of 17 mm and wing span of 33 mm. It was thought to be the teak defoliator, Hyblaea purea, but according to a 1997 report by Waterhouse, H. sanguinea occurs in Guam, but not H. purea (issg.appfa.auckland.ac.nz/database/species/reference_files/MajInv.pdf).
