 The genus Lilioceris Reitter, 1912 is distributed throughout the Palaearctic, Oriental and Ethiopian regions. According to Lopatin (1977), 40 species are known in the Palaearctic Region (mainly eastern Asia). In Korea, the genus is represented by eight species as Lilioceris (Chujoita) gibba (Baly, 1861), Lilioceris (Lilioceris) cyaneicollis (Pic, 1916), L. (L.) merdigera (Linnaeus, 1758), L. (L.) ruficollis (Baly, 1865), L. (L.) rufometallica(Pic, 1923), L. (L.) scapularis (Baly, 1859), L. (L.) sinica(Heyden, 1887) and L. (L.) triplagiata (Jacoby, 1888) (Lee and An, 2001). Many of them are important pests on medicinal plants and garden flowers [(lily; yam; etc) Lee et al., 200;, Jang et al., 2010; Kwon et al., 2010]. There have been a few studies on the adult taxonomy of Korean Lilioceris (Gressitt and Kimoto, 1961; An et al., 1986; An and Kwon, 1995; An, 1995, 1996, 1998; Lee and An, 2001). Although the main damage to the plants is caused by their larvae, nothing is known about the larvae of Korean Lilioceris. L. (L.) ruficollis is associated with Dioscorea (Dioscoreaceae), especially D. septemioba which is a well-known medicinal plant in Korea.

 In the present paper, detailed descriptions and illustrations of the larva of L. (L.) ruficollis are provided for the first time. Some remarks on their biology are also given.

Materials and Methods

 Larvae of L. (L.) ruficollis were reared on the host plants,Dioscorea spp. in the laboratory. The specimens used in this study were preserved in 70% ethyl alcohol. For morphological study, they were cleared in 10% KOH solution for 30 minutes and then rinsed in water. The dissection was done under a stereoscopic microscope (SZX12; Olympus, Japan). For morphological studies of the minute structure, slides were made for the body part and observed through the compound microscope (SZ4045; Olympus, Japan). The terminology follows Anderson (1947) and Kimoto (1962).

Materials examined

 Materials examined. 10 exs., Doreokdo Isl., Yeosu City, Jeollanam-do, 29.V. 2010, J.Y. Park; 20 exs., Sanggyedo Isl., Yeosu City, Jeollanam-do, 13. VI. 2010, J.Y. Park.


 Distribution. Korea, China, Japan.

Host plant

 Host plant. Dioscorea spp. (D. septemioba, D. batatas and D.japonica)


 Remarks. This species is easily separable from the known Criocerine larvae by numerous spines present on mosaic-like microsculpture of the tergum except for the prothorax.

Biological note

Biological note. This species has a single generation per year, overwinters in the adult stage. Adults appear in early April, begin ovipositing in early May. Eggs are laid singly inside or surface of the leaf. The larvae have a habit of accumulating their feces on their body, which serves them as a protection. The body of the larvae can also be enclosed in mucus. They then burrow themselves underground to pupate in a cocoon formed by saliva and small particles of soil. The emergence of adults starts in early June and lasts until later July. The total life cycle from egg to adult ranged from 30 to 35 days room temperature.
