The aspen hoverfly Hammerschmidtia ferruginea (Fallén)(Diptera, Syrphidae) in Deeside
After a gap of some 30 years the presence of the aspen hoverfly Hammerschmidtia ferruginea (Fallén, 1817), is confirmed in Deeside, Aberdeenshire. The methods used to re-establish the population are discussed.MacGowan, Iain

The organics revolution: new narratives and how we can achieve them
Organic remains from excavated sites include a wide range of materials, from distinct organisms (‘ecofacts’) to biomolecules. Biomolecules provide a variety of new research avenues, while ecofacts with longer histories of study are now being re-harnessed in unexpected ways. These resources are unlocking research potential, transcending what was previously imagined...Johnston, P ; Booth, T ; Carlin, N ; Cramp, L ; Edwards, B …

Molecular fingerprints resolve affinities of Rhynie chert organic fossils
The affinities of extinct organisms are often difficult to resolve using morphological data alone. Chemical analysis of carbonaceous specimens can complement traditional approaches, but the search for taxon-specific signals in ancient, thermally altered organic matter is challenging and controversial, partly because suitable positive controls are lacking. Here, we show that...Loron , C C ; Rodriguez Dzul, E ; Orr, P J ; Gromov, A V ; Fraser, Nicholas C …

Silba septuosa Mcalpine, 1964 (Diptera: Lonchaeidae) Breeding in papaya fruit in Eastern Australia, with a Revised checklist of the Australian Silba species
A total of 222 lonchaeid flies were reared from four samples of ripe papaya collected at Yamba (-29.442° 153.364°) in eastern Australia during October and November 2021, during work on a tephritid fruit fly. The lonchaeids were identified as Silba septuosa McAlpine, a little-known species represented by just a few...Fay, H A C ; MacGowan, Iain

A new species of Earomyia Zetterstedt, 1842 (Diptera; Lonchaeidae) from Montana, U.S.A., associated with the toxic plant Toxicoscordion venenosum (S. Watson) Rydb. (Melanthiaceae)
A new species of Earomyia Zetterstedt, 1842, namely E. melnickae sp. nov., is described from Montana, U.S.A. The new species is compared with other Nearctic Earomyia species, and its association with a highly toxic plant Toxicoscordion venenosum (S. Watson) Rydb. (Melanthiaceae) is discussed.MacGowan, Iain ; Astle, Tom

A curated DNA barcode reference library for parasitoids of northern European cyclically outbreaking geometrid moths
Large areas of forests are annually damaged or destroyed by outbreaking insect pests. Understanding the factors that trigger and terminate such population eruptions has become crucially important, as plants, plant-feeding insects, and their natural enemies may respond differentially to the ongoing changes in the global climate. In northernmost Europe, climate-driven...Nyman, Tommi ; Wutke, Saskia ; Koivisto, Elina ; Klemola, Tero ; Shaw, Mark R …

The Ordovician diversification of sea urchins: systematics of the Bothriocidaroida (Echinodermata: Echinoidea)
The echinoids of the order Bothriocidaroida represent the initial burst of sea urchin diversification. They were the first echinoids to achieve widespread biogeographical dispersal and achieved high levels of species richness compared to other clades of stem group echinoids. Following long-standing controversy regarding their phylogenetic affinities within the phylum Echinodermata,...Thompson, Jeffrey R ; Cotton, Laura J ; Candela, Yves ; Kutscher, Manfred ; Reich, Mike …

Noninvasive characterization and quantification of anthraquinones in dyed woolen threads by visible diffuse reflectance spectroscopy
The anthraquinone components of the roots of various species of madder (like Rubia tinctorum L. and Rubia peregrina L.) have been used for millennia as red colorants in textiles, carpets, tapestries, and other objects. To understand the selection and preparation of dyestuffs in various cultures and historical periods, these dyes...Chavanne, Clarisse ; Troalen, Lore G ; Fronty, Isabelle Bardies ; Buléon, Pascal ; Walter, Philippe

Identification of the Afrotropical lance fly Silba laevis (Bezzi, 1920) (Diptera: Lonchaeidae) imported into the United Kingdom
The lonchaeid or lance fly Silba laevis (Bezzi, 1920) is recorded for the first time on aubergine (Solanum melongena L.) having been successfully reared from aubergines imported into the United Kingdom (U.K.). The following manuscript provides detailed photographs and drawings of S. laevis, reviews recent interception data and briefly comments...Solanum, Lonchaeidae, aubergine, plant-health, Silba, and Kenya

A new genus and species of gall midges the tribe Winnertziini (Diptera, Cecidomyiidae, Porricondylinae) from lower Eocene Fushun amber from China
The new taxon, Fushuniola mai Fedotova & Perkovsky, gen. et sp. nov., is described from a single female from the lower Eocene (Ypresian) Fushun amber from China. This is the second record of Cecidomyiidae known from Fushun amber. The first record is Cecidomyia bujunensis Naora. The new species is characterized...
