Photos show the egg (A), larva (B), pupa (C) and adult (D) of Ophraella communa LeSage (Coleoptera: Chrysomelidae). The beetle was first discovered on plants of the invasive weed, Ambrosia artemisiifolia L. in the suburb of Nanjing city, Jiangsu province, eastern China in 2001. As an important natural enemy of A. artemisiifolia, it has a significant control effect on A. artemisiifolia in southern China. In this issue (pp. 631-638), the results of a study on the effects of rapid cold hardening in different intensities on the physiological indices related to cold-tolerance in O. cammuna adults were reported. Photos were taken by ZHOU Zhong-Shi in Linxiang (A, B, and D) and Miluo (C), Hunan province in July, 2007 and June, 2008, respectively.
