Abstract
Abstract Life history of Caenis lubrica Tong and Dudgeon, 2002 (Ephemeroptera: Caenidae) was studied for the first time. We investigated it in Pangxie Stream, which feeds into the Xiangxi River Bay, Three Gorges Reservoir in subtropical Central China. Monthly samples of larvae were taken from January to December, 2017. Caenis lubrica was determined to exhibit trivoltinism in this system, having an overwintering generation and two summer generations. The cohort production interval (CPI) of the overwintering generation was six months, from November to April, and the CPIs of the two summer generations were one month each, from June to July and from July to August. The Accumulated Degree Days of C. lubrica for larval development of the overwintering generation and the two summer generations were estimated to be 1829.24 °C, 904.84 °C, and 859.83 °C, respectively.
期刊介绍：
Aquatic Insects is an international journal publishing original research on the systematics, biology, and ecology of aquatic and semi-aquatic insects.
The subject of the research is aquatic and semi-aquatic insects, comprising taxa of four primary orders, the Ephemeroptera, Odonata, Plecoptera, and Trichoptera but also aquatic and semi-aquatic families of Hemiptera, Coleoptera, and Diptera, as well as specific representatives of Hymenoptera , Lepidoptera, Mecoptera, Megaloptera , and Neuroptera that occur in lotic and lentic habitats during part of their life cycle. Studies on other aquatic Hexapoda (i.e., Collembola) will be only accepted if space permits. Papers on other aquatic Arthropoda (e.g., Crustacea) will not be considered, except for those closely related to aquatic and semi-aquatic insects (e.g., water mites as insect parasites).
The topic of the research may include a wide range of biological fields. Taxonomic revisions and descriptions of individual species will be accepted especially if additional information is included on habitat preferences, species co-existing, behavior, phenology, collecting methods, etc., that are of general interest to an international readership. Descriptions based on single specimens are discouraged.
Detailed studies on morphology, physiology, behavior, and phenology of aquatic insects in all stadia of their life cycle are welcome as well as the papers with molecular and phylogenetic analyses, especially if they discuss evolutionary processes of the biological, ecological, and faunistic formation of the group.
