Abstract: Objective Objective To understand the structure characteristics of hypopus of Caloglyphus berlesei. Methods Methods The hy? popus of C. berlesei was collected from the feed of Chinese Polyphaga，and was made into the conventional glass specimens. The structure characteristics of hypopus of C. berlesei were observed by an optical microscope. Results Results The hypopus of C. ber? lesei had 4 pairs of legs，and the foot claws and tarsus were well?developed. The structural features were shown，such as the se? tae of tibia and setae of genu. Genital plates were obviously ossified. Conclusion Conclusion The research on hypopus of Caloglyphus ber? lesei provides the reference for its further scientific classification and research on the life cycle.
