Odonata (Insecta) de tres embalses del Estado de Tlaxcala

Abstract

Nine species and a genus of Odonata are recorded from three freshwater bodies which are AtlangatepecandApizaquitoandBuenavista reservoirs. Also local biodiversity and some ecological aspects onOdonataproceedingfrom the study areas. From a wholesamplingwasobtained a total of 422 adult organismswhich belong to eight genera: :Ischnura, Enallagma, Argia, Hesperagrion, Aeshna, Sympetrulm, LibellulaandErpetogomphus.s. On the basis ofabundanceand frequency)'best represented species were lschnuradenticollis and Enallagmapraevarum. Anisopteraand Zygoptera orderswere alsocollected at nymphal states mainlyfrom January to march although theywere observed through all year longand they are part ofaquatic communities and were found in submerged and emerged vegetation where Umbelliferae and Cyperaceaefanerogamae familieswere dominant and usually are used by adults for egg laying and rest.
