Notes on the host-feeding and hyperparasitic behaviours of Itoplectis species (Hymenoptera: Ichneumonidae, Pimplinae)
Dissections of campoplegine ichneumonid prepupae in cocoons parasitised by Itoplectis maculator and I. aterrima revealed that both are truly endoparasitic in this context, and that campoplegine prepupae remain capable of movement for a time following parasitisation by these Itoplectis species. Oviposition and host-feeding behaviours by the two Itoplectis species are...Shaw, Mark R

Moth populations and bad weather – four speculative observations
There is no doubt in my mind that fifty years ago substantial defoliation of more than just spindle and bird cherry trees was not really unusual; that the regular cleaning of car headlamps and even radiator grills was necessary in summer; that garden buddleia and valerian were always plastered with...Shaw, Mark R

A molecular phylogeny of the parasitoid wasp subfamily Rogadinae (Ichneumonoidea: Braconidae) with descriptions of three new genera
A molecular phylogeny of the subfamily Rogadinae is presented for 469 species in 52 genera representing all tribes and subtribes. The data comprise cytochrome c oxidase I sequences (DNA barcodes), together with a broad representation of 28S rDNA D2-D3 expansion region, EF1-α gene and 16S rDNA fragments. To test monophyly,...Quicke, Donald L J ; Fagan-Jeffries, Erinn P ; Jasso-Martínez, Jovana M ; Zaldívar-Riverón, Alejandro ; Shaw, Mark R …

Two males, one female: triplet-style mating behaviour in the Darwin wasp Xorides ater (Gravenhorst, 1829) (Hymenoptera, Ichneumonidae, Xoridinae) in the Swiss Alps
The Darwin wasp Xorides ater is a solitary idiobiont ectoparasitoid of wood-boring beetle larvae. It occurs across the Palaearctic, and in Switzerland seems to be restricted to areas above 980 m altitude. Very little is known about its biology and behaviour. We here report three separate instances of a female...Shaw, Mark R ; Giannotta, Madalene ; Herrera-Flórez, Andrés F ; Klopfstein, Seraina

The remarkable biology of a new species of Gelis Thunberg, 1827 (Ichneumonidae, Phygadeuontinae), a solitary endoparasitoid of fresh eggs of Timarcha (Coleoptera, Chrysomelidae)
A new species, Gelis timarchae Schwarz, Shaw & Kan, is figured and described from specimens reared as a solitary endoparasitoid of fresh eggs of Timarcha nicaeensis in the south of France. Oviposition behaviour of the adult parasitoid, directly into the host cytoplasm, is described and links to videos are given....Shaw, Mark R ; Kan, Pieter ; Kan-van Limburg Stirum, Brigitte ; Schwarz, Martin
