The nest surfaces were observed with a stereomicroscope and scanning electron microscope (SEM). In the V orientalis nest, the average thickness of the fibers was 13.47 mu m, the nitrogen concentration was 18.75%, the percentages of the fibers, saliva, soil and the water absorption capacity were calculated to be 20%, 20%, 60% and 91%, respectively. In the V crabro nest, the average thickness of the fibers was 11.48 mu m and the nitrogen concentration was 27.93%. The percentages of fiber, saliva and the water absorption capacity were calculated to be 23%, 77% and 100%, respectively.eninfo:eu-repo/semantics/openAccessVespa orientalisVespa crabronest materialphysical propertiesSEMArticle63244945510.2298/ABS1102449B2-s2.0-79961185944Q3WOS:000291130000019Q4
