A swarm of Pantala flavescens (Fabricius, 1798) observed in a section of the Barbate River in Cádiz is described. In addition, the reproduction of the species is confirmed in the La Breña and Marismas del Barbate Natural Park. These are the first records of migratory and reproductive behaviour of the species since its presence was first detected in the Iberian Peninsula (BERNAL-SÁNCHEZ & CONESA-GARCÍA, 2021). A possible migratory path of this swarm is also proposed, as well as its dispersion in the Iberian Peninsula. [ABSTRACT FROM AUTHOR]

High Andean lakes are ecosystems affected by multiple anthropogenic pressures that alter water quality and biotic communities, and aquatic macroinvertebrates are excellent bioindicators for these ecosystems. The present work analyzes the dynamics of the macroinvertebrate community associated with Egeria densa, the relationship with physicochemical variables, biotic indices, and predatorprey interaction in the littoral of Lake Tota. This work was developed in three campaigns on nine sampling stations on the perimeter of the lake. Among the findings, Hyallela sp. (30 %) and Dicrotendipes sp. (27 %) are the most abundant and dominant taxa of the study, being bioindicators of the presence of decomposing organic matter and decrease in water quality. ANOVA analysis of the physicochemical variables of water and nutrients of Egeria densa showed significant differences at the temporal level. The biotic indices showed differences in water quality, determining a possible zoning of this parameter along the coast. Finally, to identify community relationships, a predatorprey model is presented, with Hyalella sp. as prey and Ischnura sp. as predator through the Lotka-Volterra equations, finding that there is agreement between the behavior of measured and simulated abundances. In this way, the trophic dynamics contribute to understand the communities and their projection in time in relation to the environmental conditions of the littoral zone. [ABSTRACT FROM AUTHOR]

The knowledge of aquatic biodiversity in lentic ecosystems is scarce in many regions of the world. Therefore, it was considered important to accomplish preliminary assessments of benthic fauna associated with low depths in three sampling subaquatic fringes between 0 and 10 m on a rocky shore along the northeast area of Coatepeque Lake, El Salvador. The most abundant families were Thiaridae (Gastropoda), Hyalellidae (Malacostraca, Amphipoda), and Coenagrionidae (Insecta, Odonata) from the edge to a depth of 2,5 m. A reduced species richness and abundance were found in fine sediments (10 m) in comparison to shallower strata, as well as a lot of empty shells of the Thiaridae family and cephalic capsules of chironomid larvae (Insecta, Diptera).

We present here the results of the odonate surveys carried out in the region of La Sagra (Toledo, Spain) between 2018 and 2021. The total number of records amounted to 832. The number of recognised species was 36. The 33 species seen more than once belong 57.58% to Anisoptera and 42.4% to Zygoptera. The most abundant chorotypes are European-Ethiopian (18.18%) and Western Pan-Palaearctic (18.18%). Three species are classified as vulnerable: Coenagrion scitulum, Coenagrion mercuriale and Onychogomphus costae. Biodiversity hotspots are squares 30SVK22, 30TVK23 and 30TVK24. The species Ischnura graellsii and Ischnura elegans are found syntopic in La Sagra. Hybridisation between the two is possible. [ABSTRACT FROM AUTHOR]

Odonates constitute an order of paleopteran insects important to ecosystems because their role as generalist predators and some of their species are considered bioindicators of the environmental quality. The establishment, maintenance and growth of scientific collections that include this group may encourage their research. To this end, we are making public the creation of the odonates collection (COD-UAEH) of the Biological Research Center of the Autonomous University of the State of Hidalgo is announced. This collection contains 1,180 adult individuals belonging to ten families, 43 genera and 104 species collected in different states of the country, but mainly in the states of Hidalgo and Puebla. The incorporation of immature states has not been undertaken yet. 54% of the specimens belong to the Anisoptera suborder, which is represented by the families Aeshnidae, Cordulegastridae, Gomphidae and Libellulidae, for 26 genera and 56 species. The remaining 46% belong to the suborder Zygoptera, which includes the families Calopterygidae, Coenagrionidae, Heteragrionidae, Lestidae, Thaumatoneuridae and Platystictidae, with 17 genera and 48 species. Every specimen included in the collection has been identified to the taxonomic level of species. It is worth mentioning that the collection contains the record of a female belonging to the Megaloprepus caerulatus (Drury, 1782) species, as well as a montage in cardboard of the extended wings build to make an easier photograph taking and the wing venation comparison required for the identification of genera.

Odonates are hemimetabolous insects that play an important role in aquatic ecosystems. They are an indispensable group in entomological collections, such as those of the Charles Ramsden de la Torre Museum of Natural History at the Universidad de Oriente. The objective of this work is to inventory the Cuban specimens of the Odonata order deposited in the collection of the Charles Ramsden Museum of Natural History, through the quantification and review of the total number of dragonfly individuals and the data on their labels. With this information, tables and graphs were made that illustrate the richness of said collection, which has a total of 530 specimens, belonging to 57 species of 33 genera and seven families of the Anisoptera and Zygoptera suborders. Libellulidae was the best represented family followed by Coenagrionidae, in correspondence with the diversity and abundance that they exhibit worldwide. Four of the six Cuban endemics are present. Pastor Alayo was the entomologist with the greatest contribution to the group's collection, being appointed curator of the museum and an active collector of all orders of insects in localities of the eastern region, fundamentally. The state of conservation of the collection is optimal and with a promising future. [ABSTRACT FROM AUTHOR]

The wetland ecosystems of the middle Atrato basin have been affected by factors such as mining, which interrupt the natural ecological dynamics of these aquatic communities, including the assemblage of aquatic macroinvertebrates. The effect of gold mining contamination in the Pla-za Seca marsh, Middle Atrato basin, Chocó, Colombia, was determined. The structure and dynamics were analyzed. Macroinvertebrate specimens were collected from substrates such as macrophytes, sediment and riparian vegetation, fixed with 70% alcohol; physicochemical and hydrological parameters were measured. A total of 175 organisms were collected, distributed in 2 classes, 7 orders, 22 families and 27 genera. The order Odonata was the most representative (34%), followed by Coleoptera (28%). The Shannon-Wiener diversity index showed low values (1.92 bits/ind). The physicochemical variables were influenced by mining activity in the areas surrounding the marsh. [ABSTRACT FROM AUTHOR]

This paper describes the update of the red list of dragonflies in Wallonia 20 years after the previous assessment. The analysis is based on a dataset of nearly 200,000 observations from more than 1700 observers as well as on trend analyses carried out in the framework of complementary studies. The revision of the status of the 67 Walloon dragonfly species shows that, among the assessed species, 2 are extinct (3.3%), no species is critically endangered, 5 are endangered (8.3%), 10 are vulnerable (16.7%), 4 are near threatened (6.7%) and 39 are currently not threatened (65%). In comparison with the previous red list, the status of dragonfly species in Wallonia is more favourable. However, this positive evolution may be uncertain in view of the ongoing climate changes.

The dragonfly fauna of four reserves located in Campos y Malezales ecoregion, Misiones Province, was studied between 2014 and 2018. Thirty-six species and eight morphotypes, belonging to six families of Anisoptera and Zygoptera were identified, representing together 22% of the known species in the Province. Libellulidae was the family with the highest number of species recorded (22 species) followed by Coenagrionidae (15 species). Two species were new records, one for Argentina (Minagrion waltheri Selys), and one for Misiones province (Tholymis citrina Hagen). [ABSTRACT FROM AUTHOR]

The fragmentation of aquatic and riparian environments has damaged diversity into ecosystems. These injuries are pronounced in areas as tropical dry forests in Colombia, which are endangered zones that could be disappear in few years. In this situation, diversity and composition in Odonata insects, which are influenced by abiotic factors, could be excellent tools for understanding environmental status. Thus, we aim to observe changes in Odonata diversity and composition in different riparian vegetation during a year, along a stream from a remnant of dry forest. At the same time, we hypothesize that there are differences in Odonata diversity and composition. To take this, we sampled Odonata, larvae and adults, and environmental variables in four sampling stations, with different riparian vegetation during a year. We collected a total of 272 specimens corresponding to 16 species. In one hand, we noted variations in Odonata composition, showed in species records and similarity index. In other hand, we do not observe differences in Odonata diversity. Lastly, we approve in part our hypothesis exposing only Odonata composition changes with riparian vegetation, during sampling year.

The transference of biomass to terrestrial ecosystems is carried out in part by the adults of aquatic insects after their emergence from water, as it is in the case of odonates. The aim of this study is to characterize the emergence pattern of an odonate assemblage in an artificial lentic habitat of the National Botanical Garden of Cuba, from the harvest of exuviae. Fifty two samplings were carried out with a frequency of once a week, and an interval of seven to nine days, in four transect of 8 m2. To characterize the emergence, the seasonal climate model was considered: rainy, poorly rainy and transition seasons. The change in climatic variables and habitat characteristics was registered, and was related to the emergence pattern. The variation in the use of resources during emergence was described. The emergence with a constant volume of water turned out to be asynchronous, with a predominance of accidental species and unequal abundance distribution. The rainy period was the season with the highest percentage of emergence, in which rainfall and relative humidity were the factors that most influenced the emergence pattern. The plants were the most used emergence substrate, and the decrease in vegetation cover corresponded to the alternative use of other substrates. [ABSTRACT FROM AUTHOR]

A global review of the postage stamp inventory is presented with the representation of dragonflies and damselflies (Insecta: Odonata) as biological organisms. To this end, an exhaustive search was carried out in literature specialized in entomophilately, in addition to the use of the internet. 426 stamps issued by 113 countries were found, in addition to 102 postal documents (postmarks, first day envelopes, souvenir sheets). The first record of an Odonata in a postage stamp is made by Japan in 1923, while the years 2000, 2011 and 2013 stand out when emitting the greatest number of stamps with these insects. Taxonomically, a total of 182 species is recorded, representing 3.06% of the species recognized for the order. Of the stamps issued, 6.59% represent species in some risk category based on the IUCN.

The present work updates the systematic of the order Odonata in Cuba to 88 species, of the subordeners Zygoptera and Anisoptera, included in six families and 41 genera. Coryphaeschna apeora Paulson, 1994; Libellula gaigei Gloyd, 1938 and Tramea binotata (Rambur, 1842) are considered new records. The order presents six endemic and they were carried out two you adjust taxonomic for the family Protoneuridae and the genus Microneura. Central Cuba is the region least studied for order, and Ciénaga de Zapata and Sagua-Baracoa are the regions of greatest interest for studies with odonates. [ABSTRACT FROM AUTHOR]

Emergence patterns of Odonata (Insecta) from a lotic habitat in Eastern Cuba. The emergence patterns of tropical odonates (dragonflies and damselflies) are scarcely known. We studied the emergence patterns of odonates in a freshwater lotic system in Giro, Northern Santiago de Cuba, between January and December 2008. We visited the locality between 09:00 and 14:00, on a weekly basis, and collected exuviae from a fixed section (8 x 1 m2) offshore, along the riparian vegetation. We collected data on species composition and, for each species, abundance, relative biomass and emergence pattern. We collected 443 exuviae belonging to 22 species: seven Zygoptera and 15 Anisoptera. Half of the annual Odonata emergence took place in the dry season (December to March) with the highest value in February (25 %). For species for which we found seven or more exuviae per month, Enallagma coecum and Macrothemis celeno tended to be a synchronal emergence. We also found temporal segregation of the emergence pattern between M. celeno and Protoneura capillaris, Neoneura maria, Progomphus integer and Scapanea frontalis. These differences were probably related to the highest annual fluctuations of temperature, relative humidity and number of rainy days per month. We concluded that there is an asynchrony and heterogeneity in Odonata emergence times in the studied freshwater lotic system. [ABSTRACT FROM AUTHOR]

The knowledge about population structure and dynamics of some neotropical species, especially those living in lotic systems is still barely studied. This study had the aim to assess if the conservation status of some lotic systems, is related to some demographic variables of P. gigantea, so this may be used as a model for ecological monitoring. For this, we evaluated the population structure of P. gigantea three times per month (almost one sampling event every eight days) in four streams of the state of Antioquia, Colombia, from March-June 2009. The specimens were collected using entomological nets along a transect of 200m in the littoral zone of each stream. The insects were marked on the wings and the population size was estimated with the mark-recapture method. Our results showed that the largest population size was recorded for the stream "La Catedral" with aprox 299 individuals, followed by the stream "La Doctora" with 218 individuals. Nevertheless, no significant differences in population size among the evaluated streams were found; and no statistical relationships were found between vegetation variables and the population size of P. gigantea. However, taking into account the limited dispersal capacity of P. gigantea, its survival in the studied streams was considered to be at risk, due to the continuous modification of large riparian forest areas, which cause the increase of forest patches, with different levels of interconnection, and hinder long-term permanence of populations.

A preliminary inventory of the aquatic insects from the Somuncura plateau and its area of influence (Patagonia, Argentina) is presented. It was done on the basis of the study of collections and previous records of species belonging to the orders Ephemeroptera, Odonata, Hemiptera (Heteroptera), Trichoptera, Diptera (families Ceratopogonidae, Culicidae, and Psychodidae) and Coleoptera. Different kinds of environments were surveyed in 14 localities. Seventy eight species grouped in 51 genera and 26 families were registered, and 33 species are new records for the area. Eighty three % of the registered genera are widely distributed (neotropical, american or cosmopolitan), while 41 % of the species exhibit patagonic or andean distribution. [ABSTRACT FROM AUTHOR]

We studied the community of aquatic insects inhabiting both temporary pools and permanent ponds occuring in Buenos Aires City. A total of 3436 rain pools were examined, and six permanent ponds at the "Reserva Ecológica Costanera Sur" in the Río de la Plata riverside were visited 149 times. A total of 85 taxa were recorded from both habitats, included in five orders of Insecta. The order Coleoptera showed the highest diversity values (36 taxa), followed by Diptera (27), Heteroptera (17), Odonata (4), and Ephemeroptera (1). High values of richness were observed in temporary pools (58 taxa) and permanent ponds without floating vegetation (64 taxa). The diversity index for temporary ponds was significantly (p<0,05) lower than in permanent habitats. [ABSTRACT FROM AUTHOR]
