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,... -

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

Notes on the biology, morphology and generic placement of “Hellwigia” obscura Gravenhorst (Hymenoptera: Ichneumonidae, Ophioninae)
The ophionine ichneumonid known as Hellwigia obscura has been reared for the first time, from larvae of Horisme sp. (Lepidoptera: Geometridae) feeding on Clematis vitalba in The Netherlands. The cocoon and the parasitoid’s means of emergence are figured, as are some features of the adult. On a balance of morphological...Shaw, Mark R ; Voogd, Jeroen

Braconid and ichneumonid (Hymenoptera) parasitoid wasps of Lepidoptera from the Maltese Islands
Fourteen species of Ichneumonidae are here recorded from the Maltese Islands. Of these, all were reared from Lepidoptera hosts with the exception of Netelia (Paropheltes) inedita (Kokujev) which was collected from a malaise trap. Of these, the following species (or genera) are here reported for the first time from the...Mifsud, David ; Farrugia, Lucia ; Shaw, Mark R

Wolbachia and DNA barcoding insects: patterns, potential and problems
Wolbachia is a genus of bacterial endosymbionts that impacts the breeding systems of their hosts. Wolbachia can confuse the patterns of mitochondrial variation, including DNA barcodes, because it influences the pathways through which mitochondria are inherited. We examined the extent to which these endosymbionts are detected in routine DNA barcoding,...Smith, M A ; Bertrand, C ; Crosby, K ; Eveleigh, E S ; Fernandez-Triana, J …

The identity of Scambus planatus (Hartig, 1838) and Scambus ventricosus (Tschek, 1871) as seasonal forms of Scambus calobatus (Gravenhorst, 1829) in Europe (Hymenoptera, Ichneumonidae, Pimplinae, Ephialtini)
Through both natural and experimental rearings, supported by DNA sequence data (CO1, ITS2 and EF1α) as well as examination of material in collections, it is shown that the European nominal taxa Scambus planatus and Scambus ventricosus comprise the spring-emerging generation of Scambus calobatus, the typical form of which occurs as...Shaw, Mark R ; Jennings, M T ; Quicke, D L J

The changing use of the ovipositor in host shifts by ichneumonid ectoparasitoids of spiders (Hymenoptera, Ichneumonidae, Pimplinae)
Accurate egg placement into or onto a living host is an essential ability for many parasitoids, and changes in associated phenotypes, such as ovipositor morphology and behaviour, correlate with significant host shifts. Here, we report that in the ichneumonid group of koinobiont spider-ectoparasitoids (“polysphinctines”), several putatively ancestral taxa (clade I...Takasuka, Keizo ; Fritzén, Niclas R ; Tanaka, Yoshihiro ; Matsumoto, Rikio ; Maeto, Kaoru …

Further notes on the biology of Pseudavga flavicoxa Tobias, 1964 (Hymenoptera, Braconidae, Rhysipolinae)
Pseudavga flavicoxa, a solitary koinobiont ectoparasitoid of Bucculatrix thoracella, attacks host larvae early rather than late in their final instar, subsequent development of the parasitoid then occurring within the host cocoon. This paper supplements an earlier contribution outlining other aspects of its biology and taxonomy. The host is stung repeatedly,...Shaw, Mark R

Evolution of the parasitic wasp subfamily Rogadinae(Branconidae): phylogeny and evolution of lepidopteran host ranges and mummy characteristics.
Background: The braconid subfamily Rogadinae is a large, cosmopolitan group of endoparasitoid wasps characterised by 'mummifying' their lepidopteran host larvae, from which the adult subsequently emerges. Rogadines attack a variety of both macro- and microlepidopteran taxa, although the speciose genus Aleiodes almost exclusively attacks macrolepidopterans. Here, we investigate the phylogenetic...Shaw, Mark R

Illustrated notes on the biology of Sphinctus serotinus Gravenhorst (Hymenoptera, Tryphoninae, Sphinctini)
Field and experimental observations on the European ichneumonid Sphinctus serotinus as a koinobiont ectoparasitoid of the limacodid moth Apoda limacodes are recorded. The egg is anchored into the extremely thick cuticle of its host but not deeply enough so that it would survive host ecdysis. That may explain the late...Shaw, Mark R ; Voogd, Jeroen

Unusually for Ichneumonidae, Trogus lapidator emerges through a hole in the pupal wing case of its papilionid butterfly host that is made largely by a liquid secretion that softens and disintegrates the host tissue. The mandibles are deployed to help spread the secretion, but only towards the very end of...Shaw, Mark R ; Kan, Pieter ; Kan-van Limburg Stirum, Brigitte

A widespread European nocturnal ichneumonid, Ophion luteus, is shown to be a parasitoid of at least two species of noctuid moth, Agrotis exclamationis and A. segetum, probably most frequently a parasitoid of the former. The taxonomy, nomenclature and diagnostic features of this species are discussed. Possible explanations for a spring-flying...Broad, Gavin R ; Schnee, Heinz ; Shaw, Mark R
