Luffia lapidella (Goeze, 1783) (Lepidoptera: Psychidae) proved to be the host of Choeras gielisi van Achterberg (Braconidae: Microgastrinae), new to Britain
Choeras gielisi is recorded from Britain for the first time, on the basis of two female and two male specimens reared solitarily from sexual and parthenogenetic forms of the Luffia lapidella at different sites. These rearings, the first with clear host detemination, provide strong evidence that the type specimen of...Shaw, Mark R

Observations on co-existing late-instar caterpillars of the Orange-tip butterfly, Anthocharis cardamines (Linnaeus) (Lepidoptera: Pieridae)
Co-existence between late instar larvae of Anthocharis cardamines on multiple occupied Lunaria annua plants was monitored in a suburban Edinburgh garden and a stand-off between final instar larvae on Sisymbrium officinale in countryside near Leipzig was recorded photographically. Occupation of mauve-flowered Lunaria plants was significantly higher than white-flowered ones. The...Shaw, Mark R ; Otto, Helene

Overwintering behaviour of Diphyus quadripunctorius (Müller) (Hymenoptera: Ichneumonidae, Ichneumoninae) in south-east Scotland
Overwintering behaviour of adult females of the ichneumonid Diphyus quadripunctorius (Müller) in caves and mines in south east Scotland was monitored over two successive winters. This is a univoltine larva-pupal parasitoid of certain Noctua species, parasitizing their larvae in spring. The species was found in rather few of the sites...Baird, Katty ; Shaw, Mark R

A second British specimen of Coleocentrus Excivator (Poda) (Hymenoptera:Ichneumonidae, Acaenitinae) from Scotland
A second British specimen of the spectacular ichneumonid. Coleocentrus Excivator is recorded from Tomich, Inverness-shire, some 80 km NNW from the site at which the first was found 34 years previously. The species is illustrated and notes are given to facilitate identification. Some indications of host and biology are tentatively...Shaw, Mark R ; Lyszkowski, Richard M

Two examples of anterior / posterior gynandromorphism in Ichneumonidae (Hymenoptera)
Two specimens of Ichneumonidae exhibiting interior/posterior gynandromorphism are described. In both the specimens of Ephialtes manifestator (L.) (Ichneumonidae: Pimplinae) and Cylloceria sylvestris (Gravenhorst) (Ichneumonidae: Cylloceriinae), the head is female (as is the mesosoma of E. manifestator) and the metasoma is male. A potential mechanism for generation of transverse (anterior/posterior) gynandromorphs...Shaw, Mark R ; Broad, Gavin R

Anatomy, reach and classification of the parasitoid complex of a common British moth, Anthophila fabriciana (L.) (Choreutidae)
The small plurivoltine moth Anthophila fabriciana is widespread and often abundant in Britain wherever its main larval foodplant, stinging nettle, occurs. It overwinters as a larva (first generation) then has one or more partly overlapping summer broods (notionally second generation). A total of 5017 larvae were collected and reared from...Shaw, Mark R

Two hundred and twenty-five species of reared western Palaearctic Campopleginae (Hymenoptera: Ichneumonidae)in the National Museums of Scotland, with descriptions of new species of Campoplex and Diadegama, and records of fifty-five species new to Britain
Host and in some cases detailed rearing data are presented for 225 species of western Palaearctic Campopleginae from reared material in the National Museums of Scotland, with comments on phenology of all species and particular attention to their means of overwintering. For many species there were previously no host records....
