Oecocecis is a genus of moths in the family Gelechiidae. It contains the species Oecocecis guyonella, which is found in southern Europe (France, Sicily and Cyprus), North Africa and Syria.[1]
The larvae feed on Limoniastrum guyonianum and Limoniastrum monopetalum. They create a brownish-red hard, spherical gall on the tender branch or peduncle of their host plant.[2] Pupation takes place within the gall.[3]
