This study was examined to clarify on food habits and relationships about 4 species of superfamily Sublipalpia in Plecoptera (Insecta). Oyamia coreana fed mainly on young nymphs of Chironomidae and Heptageniidae and feeding amount of each foregut was 3∼7 individuals of Chironomidae. Paragnetina flavotincta fed on 1∼2 individuals of Heptageniidae, 1∼3 of Baetidae and 6∼9 of Chironomidae. Kiotina decorata fed on 2∼3 individuals of Heptageniidae. Megarcy ochracea fed on Chironomidae and Heptageniidae and feeding amount of each foregut was about 20 individuals of Chironomidae. Actively feeding season of these species is spring, where as, inactive in fall. Food selection except Kiotina decorata which had preference for Heptageniidae (electivity, +0.6) had for Chironomidae (+0.4∼0.8), but all of them avoided plant materials and aquatic insects of which head capsule width was over 2.0 mm.

In checking cycle decision, situation of latency breakdown that can not know that cause breakdown before device that is using examines can exist. Example such as car examination, faur and equitable spirit health examination, security device etc.. can be fatal the time. Therefore, study and examined arbor in the mountains room of family proper checking cycle.
