Butterfly–parasitoid–hostplant interactions in Western Palaearctic Hesperiidae: a DNA barcoding reference library
The study of ecological interactions between plants, phytophagous insects and their natural enemies is an essential but challenging component for understanding ecosystem dynamics. Molecular methods such as DNA barcoding can help elucidate these interactions. In this study, we employed DNA barcoding to establish hostplant and parasitoid interactions with hesperiid butterflies,... -

Characterisation of some species groups of Brachymeria (Hymenoptera: Chalcididae), with a review of the B. tibialis-group and description of a new species parasitizing Zygaena pupae (Lepidoptera: Zygaenidae)
The Brachymeria tibialis species group is newly recognized and diagnosed together with the Brachymeria annulata, femorata, kassiliensis and lasus species groups also newly defined. In these diagnoses a few morphological characters of the ventral part of the mesosoma, discovered in this study, are proposed to help differentiate the groups. The...Delvare, Gérard ; Shaw, Mark R

Rearings of four European Microgastrinae (Hymenoptera: Braconidae), three new to Britain including a new species of Cotesia Cameron, 1891
Cotesia carterocephali sp. nov. is described from a single gregarious brood reared from a posthibernation final instar larva of the hesperiid butterfly Carterocephalus palaemon in Scotland. Details of English rearings of two other Microgastrinae recorded from Britain for the first time are also given: Distatrix pompelon, gregariously from the erebiid... -

New fossils from the London Clay show that the Eocene Masillaraptoridae are stem group representatives of falcons (Aves, Falconiformes)
The Eocene taxon Masillaraptoridae includes long-legged, raptorial birds, the phylogenetic affinities of which are poorly resolved. Here, fossils from the London Clay of Walton-on-the-Naze (Essex, U.K.) are described, which corroborate the hypothesis that masillaraptorids are stem group representatives of the Falconiformes (falcons). Two partial skeletons are assigned to a new...Mayr, Gerald ; Kitchener, Andrew C

Oldest fossil loon documents a pronounced ecomorphological shift in the evolution of gaviiform birds
We describe a stem group representative of Gaviiformes (loons or divers) from the early Eocene London Clay of Walton-on-the-Naze (Essex, UK). The holotype of Nasidytes ypresianus gen. et sp. nov. is a partial skeleton including the mandible and all major limb bones. The new species is the oldest unambiguously identified...Mayr, Gerald ; Kitchener, Andrew C

Early Eocene fossil illuminates the ancestral (diurnal) ecomorphology of owls and documents a mosaic evolution of the strigiform body plan
We describe a partial skeleton of a fossil owl (Strigiformes) from the early Eocene London Clay of Walton-on-the-Naze (Essex, UK). The holotype of Ypresiglaux michaeldanielsi, gen. et sp. nov. is one of the most complete specimens of a Palaeogene owl and elucidates the poorly known ecomorphology of stem group Strigiformes....Mayr, Gerald ; Kitchener, Andrew C

Biological and morphological studies on the parasitoids (Hymenoptera, Ichneumonidae) of Aprosthema tardum (Klug) (Hymenoptera, Argidae, Sterictiphorinae) in Var, southern France
Field surveys at four neighbouring but discrete sites in southern France revealed the presence of five ichneumonid parasitoids of the -feeding sterictiphorine argid sawfly . Four of these parasitoids, , (both Ctenopelmatinae), and (both Tryphoninae), could be identified and, by also incorporating laboratory studies, the developmental biology of each was... -

Identity of wasp parasitoids (Hymenoptera) attacking Pieris brassicae (Linnaeus, 1758) (Lepidoptera: Pieridae) in South Africa
The alien invasive large cabbage white, Pieris brassicae (Linnaeus, 1758) (Pieridae), although introduced into South Africa more than 27 years ago, has not dramatically expanded its distribution, possibly because it is effectively attacked by two parasitoid wasp species. Even though there is a cohort of parasitoid species associated with P.... -

Larval parasitism in a specialist herbivore is explained by phenological synchrony and host plant availability
Parasitism is a key factor in the population dynamics of many herbivorous insects, although its impact on host populations varies widely, for instance, along latitudinal and altitudinal gradients. Understanding the sources of geographical variation in host–parasitoid interactions is crucial for reliably predicting the future success of the interacting species under...Stefanescu, Constantí ; Colom, Pau ; Barea‐Azcón, José Miguel ; Horsfield, David ; Komac, Benjamin …
