 Leaves of Ficus obliqua serve as a food source for the larvae of the butterfly species the common crow ( Euploea core ) , the no @-@ brand crow ( Euploea alcathoe ) , and the Geometer moth species Scopula epigypsa . The thrips species Gynaikothrips australis feeds on the underside of new leaves of F. obliqua , as well as F. rubiginosa and F. macrophylla . As plant cells die , nearby cells are induced into forming meristem tissue . A gall results and the leaves become distorted and curl over . The thrips remain in the galls at night and wander about in the daytime before returning in the evening , possibly to different galls about the tree . The thrips begin feeding when the tree has flushes of new growth , and the life cycle is around six weeks . At other times , thrips reside on old leaves without feeding or pupate sheltered in the bark .
