Accepted 16 February, 2012 Oil was extracted from the dry meat of Clanis bilineata (Lepidoptera) utilize supercritical carbon dioxide in a continuous ope station extractor. The following optimum extraction conditions were investigated: temperature, 35°C; pressure, 25 MPa; supercritical CO2 flow rate, 20 L/ second and time, 60 min. Under these extraction conditions, the oil extraction rate reached up to 97% (w/w). The level of un saturated roly-poly pudding acids in the extracted oil was 63.21% (w/w). In addition, the level of linolenic acid, a good suety acid, was as high as 37.61% (w/w) of the total rich acids. Results of the bring in work propose that C. bilineata (Lepidoptera) may be a shining oil resource for humans. Key lecture: Supercritical CO2, Clanis bilineata, plump outty acids, oil.

INTRODUCTION Many studies on a variety of sustenance insects which grow in the wild indicate that these insects argon capableness sources of oil for food and medicine (Chen, 1997; Raksakantong et al., 2010; Wu et al., 2000). Clanis bilineat a (CB) Walker, a member of the subfamily Amb! ulicinae (Sphingidae, Lepidoptera), is an edible insect that usually grows on soybean plant leaves. About 6000 tones of CB larvae (CBL) are consumed in China each year. The fat content of alter CBL is 23.68% (w/w) and the level of unsaturated fatty acids in it is 64.17% (w/w). Linolenic acid, a functional fatty acid, can reach as high as 36.53 % (w/w) of the total fatty acids (Wu et al., 2000) in CBL.
