Abstract:
... The first detailed description of the late-instar larva of Prionochaeta opaca (Say, 1825) is provided, with chaetotaxy, illustrations and photos. The single Nearctic representative of Cholevina and the only known larval stage of Prionochaeta Horn, 1880 is discussed and compared to other known larvae of Cholevini with special reference to its autapomorphic characters: pectinate tergal setae and fou ...

Abstract:
... The genus Ceratomia (Harris, 1839) is a widespread genus in the United States containing seven species. This genus has several species with striking color variation as larvae. Ceratomia hageni Grote, 1874 has been documented with a single larval color, contrasting with others in the genus. This paper describes and depicts two new color variations, a brown morph and a brown-yellow morph of final in ...

The numerous fossil specimens described as consecutive series of different larval stages of two species, Tchirkovaea guttata and Paimbia fenestrata (Palaeodictyoptera: Tchirkovaeidae), were reinvestigated with emphasis on comparing the development and growth of their wings with that of the wings of a recent mayfly, Cloeon dipterum. This unique fossil material was for a long time considered as undi ...

Abstract:
... Cloeon micki sp. n., a new species of baetid mayfly from China is described and illustrated based on larval and imaginal stages associated by laboratory rearing. The new species is characterised by the presence of a dark brown or dark purple elliptical marking on abdominal tergites II and V, which readily distinguishes it from other members of the genus Cloeon Leach, 1815. The known distribution o ...

The Scoliidae occur predominantly in tropical and subtropical regions and are ectoparasitoids of Scarabaeoidea larvae (especially of Melolonthinae) which are immobilised, parasitised by the female wasp in their terrestrial larval gallery and buried deeper in a special cell by the female wasp. Herein, we provided, for the first time, illustrated keys to 11 genera and 52 species of Scoliidae from Ch ...

Abstract:
... Understanding temporal regulation of development remains an important challenge. Whereas average, species-typical timing of many developmental processes has been established, less is known about inter-individual variability and correlations in timing of specific events. We addressed these questions in the context of postembryonic development in Caenorhabditis elegans. Based on patterns of locomoto ...

Abstract:
... The relationship between metapopulation stability and connectivity has long been investigated in ecology, however, most of these studies are focused on theoretical species and habitat networks, having limited ability to capture the complexity of real‐world metapopulations. Network analysis became more important in modeling connectivity, but it is still uncertain which network metrics are reliable ...

Abstract:
... Baetidae was one of the first families established for mayflies (Ephemeroptera). After more than 200 years of progressive research, Baetidae is now known as the most species‐rich family in the order. Two competing proposals of family division were proposed: Cloeoninae and Baetinae, or Protopatellata and Anteropatellata. Both classifications were established without cladistic support.

Abstract:
... A key problem faced by foragers is how to forage when resources are distributed heterogeneously in space. This heterogeneity and associated trade‐offs may change with spatial scale. Furthermore, foragers may also have to optimize acquiring multiple resources. Such complexity of decision‐making while foraging is poorly understood. We studied the butterfly Ypthima huebneri to examine how foraging de ...

Abstract:
... Sea urchin (Loxechinus albus) is one of the most important benthic resource in Chile. Due to their large-scale spatial metapopulation structure, sea urchin subpopulations are interconnected by larval dispersion, so the recovery of local abundance depends on the distance and hydrodynamic characteristics of their spatial domain. Currently, this resource is evaluated with classical stock assessment m ...
