AbstractTo understand the species composition of moths in the Heilongjiang Langxiang National Nature Reserve， a survey wasconducted using light-trapping methods from April to October 2O24 across diferent habitats （coniferous forest，broadleaf forest，mixedconiferous-broadleafforest，andshrubland）.Moths werecollectedand identified，and Simpson's dominance index，Shannon-Wiener diversity index，Pielou’s evennessindex，and Jaccard simlarityindex werecalculatedtoanalyze thediversityandsimilarityofmothcommunitiesinthese habitats.Theresultsshowed thata total of2870 mothindividuals werecolectedfromthefour habitats，belonging to74 species，71 generaand15families， withNoctuidae being thedominant family.Theshrublandhabitathadthehighest Simpsonand Shannon-Wiener indices，with valuesof0.8698and 3.O022，respectively.The broadeafforest exhibited the highest Pielou’seveess index，reachingO.8949.The highest similarity index （O.6923）wasobservedbetweentheconiferous forest and the mixed coniferous-broadleafforest.These findings indicate thatthestructureof mothcommunities iscloselyrelatedto vegetation typeand ecologicalconditions.Surveysof moth diversitycan helpdevelop targetedconservation strategies and provide a reference for assessing the quality and dynamics of the local ecological environment.
