RESUMENSe revisan las especies de crisópidos presentes en la fauna de la Península Ibérica e Islas Baleares donde, hasta la fecha, están representadas por 50 especies pertenecientes a 13 géneros. Tras una diagnosis de la familia y citar algunos elementos sobre su historial paleontológico y su distribución, se aportan algunos datos generales sobre su morfología y su biología, sus estadios juveniles y comportamiento, y se comenta una breve introducción sobre la historia en el conocimiento de la familia, y en particular en la Península Ibérica y Baleares. Se anotan algunas correcciones en las fechas de publicación de algunos taxa que afectan a la taxonomía, y por ello se propone a Rexa almerai (Navás, 1919) n. comb. como sinónima anterior de Rexa lordina Navás, 1920 n. syn. Se incluye una lista de las especies pertenecientes a la fauna de la Península Ibérica y Baleares, una clave de identificación de los imagos de las subfamilias, géneros y especies citadas, y una clave de sus larvas a nivel genérico. De cada una de estas especies se recopilan y se anotan todas las referencias bibliográficas existentes desde 1972, relativas a las especies de la zona estudiada, tanto con la denominación actualmente aceptada, como de sus sinonimias y/o cualquier otra combinación nomenclatural bajo las cuales han sido citadas. También de cada una de las especies se anotan los datos conocidos y los ahora aportados (299 nuevos ejemplares de 25 especies) sobre su distribución general, aspectos de su morfología externa y/o genital, así como de su variabilidad, estadios juveniles, biología, fenología y distribución altitudinal y geográfica en la península y archipiélago balear, en base a un total de 20.667 ejemplares estudiados.http://lsid:zoobank.org:pub:DAF40D47-BB5B-444B-9A3C-463BBB4F5382Palabras clave: Insecta; Neuroptera; Chrysopidae; Revisión; Taxonomía; Faunística; Morfología; Península Ibérica; Islas Baleares; España; Portugal. SUMMARY Green-lacewings (Insecta, Neuropterida, Neuroptera: Chrysopidae) of the Iberian Peninsula and Balearic IslandsThe present contribution reviews the green lacewing fauna of the Iberian Peninsula and Balearic Islands where, to date, 50 species belonging to 13 genera are known to occur. After a diagnosis of the family Chrysopidae, its paleontological history and distribution, as well as some general data on its morphology and biology, juvenile stages and behavior are presented. This general information is followed by a brief history of studies on the family, and particularly those on the Iberian Peninsula and Balearic Islands. Some corrections are reported for earlier publications dates that have undergone taxonomical changes. Thus, Rexa almerai (Navás, 1919) n. comb. is proposed as junior synonym of Rexa lordina Navás, 1920 n. syn.; and is included in the list of chrysopid species belonging to the fauna of the Iberian Peninsula and Balearic Islands. A key for identifying imagoes of the subfamilies, genera, and species recorded from the region and a generic level key for the larvae are presented. For th...

“…Aerial netting at 200 m above the ground (22,24,47) and captures in 12-m-high suction traps (34) clearly demonstrate that macromoths are the only large (>50 mg) insects that are abundant, high-altitude, nocturnal migrants in the United Kingdom. We can thus be highly confident that the vast majority of VLR-detected large nocturnal insect targets were macromoths, and the aerial composition of this family in the United Kingdom is dominated by A. gamma (22-25, 34, 47).…”

Little is known of the population dynamics of long-range insect migrants, and it has been suggested that the annual journeys of billions of nonhardy insects to exploit temperate zones during summer represent a sink from which future generations seldom return (the "Pied Piper" effect). We combine data from entomological radars and ground-based light traps to show that annual migrations are highly adaptive in the noctuid moth Autographa gamma (silver Y), a major agricultural pest. We estimate that 10-240 million immigrants reach the United Kingdom each spring, but that summer breeding results in a fourfold increase in the abundance of the subsequent generation of adults, all of which emigrate southward in the fall. Trajectory simulations show that 80% of emigrants will reach regions suitable for winter breeding in the Mediterranean Basin, for which our population dynamics model predicts a winter carrying capacity only 20% of that of northern Europe during the summer. We conclude not only that poleward insect migrations in spring result in major population increases, but also that the persistence of such species is dependent on summer breeding in high-latitude regions, which requires a fundamental change in our understanding of insect migration.windborne migration | source-sink dynamics

“…However, it has yet to be shown how well parasitoid migration at 12.2 m reflects numbers on the ground. What is known is that parasitoids, including Aphidius sp., migrate in good numbers at much higher altitudes of at least 200 m in southern England (Chapman et al, 2004;J. Chapman, unpublished).…”

Abstract. 1. Parasitoids are a valuable group for conservation biological control. In their role as regulators of aphid pests, it is critical that their lifecycle is synchronised with their hosts in both space and time. This is because a synchronised parasitoid community is more likely to strengthen the overall conservation biological control effect, thus damping aphid numbers and preventing potential outbreaks. One component of this host-parasitoid system was examined, that of migration, and the hypothesis that peak summer parasitoid and host migrations are synchronised in time was tested.2. Sitobion avenae Fabricius and six associated parasitoids were sampled from 1976 to 2013 using 12.2-m suction-traps from two sites in Southern England. The relationship between peak weekly S. avenae counts and their parasitoids was quantified.3. Simple regression models showed that the response of the peak parasitoids to the host was positive: generally, more parasitoids migrated with increasing numbers of aphids. Further, when averaged over time, the parasitoid migration peak date corresponded with the aphid migration peak. The co-occurrence of the peaks was between 51% and 64%. However, the summer peak in aphid migration is not steadily shifting forward with time unlike spring first flights of aphids. Cross-correlation analysis showed that there were no between-year lagged effects of aphids on parasitoids.4. These results demonstrate that the peak in migration phenology between host and parasitoid is broadly synchronised within a season. Because the threshold temperature for flight (> 12 ∘ C) was almost always exceeded in summer, the synchronising agent is likely to be crop senescence, not temperature. Studies are needed to assess the effects of climate change on the mismatch potential between parasitoids and their hosts.
