Raw data for the submitted manuscript: The Influence of Soil Organic Matter Content on the Toxicity of Pesticides to the Springtail Folsomia candida
<p>Raw data obtained from toxicity tests with the springtail Folsomia candida exposed for 28 days to chlorpyrifos, lindane, cyproconazole, carbendazim and imidacloprid in artificial soils containing 10%, 5%, 2.5% sphagnum peat, and LUFA 2.2 soil. Tests were performed following OECD guideline 232. The file includes data on springtail survival and reproduction.</p>

Springtail coloration at a finer scale: mechanisms behind vibrant Collembolan metallic colours
<p>The mechanisms and evolution of metallic structural colours are of both fundamental and applied interest, yet most work in arthropods has focused on derived butterflies and beetles with distinct hues. In particular, basal hexapods - groups with many scaled, metallic representatives – are currently poorly studied and controversial, with some recent studies suggesting either that thin- film (lamina thickness) or diffraction grating elements (longitudinal ridges, crossribs) produce these colors in early Lepidoptera and one springtail (Collembola) species. Especially the Collembolan basal scale design, consisting of a singlelamina and longitudinal ridges with smooth valleys lacking crossribs, makes them an interesting group to explore the mechanisms of metallic colouration. Using microspectroscopy, Raman spectroscopy, electron microscopy and FDTD optical modelling we investigated scale colour in seven springtail species that show clear metallic colouration. Reflectance spectra are largely uniform and exhibit a broadband metallic/golden colouration with peaks in the violet/blue region. Our simulations confirm the role of the longitudinal ridges, working in conjunction with thin-film effects to produce a broadband metallic colouration. Broadband colouration occurs through spatial colour mixing which likely results from nanoscale variation in scale thickness and ridge height and distance. These results provide crucial insights into the colour production mechanisms in a basal scale design and highlight the need for further investigation of scaled, basal arthropods.</p>
Rapid and reversible humidity-dependent colour change by water film formation in a scaled springtail: Image compilations and video recordings
<p><span>Colour is often not a static trait but can change over time either through biotic or abiotic factors. Humidity-dependent colour change can occur through either morphological change (e.g. to feather barbules in birds) or by the replacement of air by water causing a shift in refractive index, as seen in arthropod multilayer cuticles or scales. The scaled springtail <em>Lepidocyrtus</em> <em>cyaneus</em> has scales that produce color largely via thin film interference from their lamina. We observed a marked colour change from golden to violet/purple colouration in humid conditions. Light microscopy, microspectrophotometry, contact angle goniometry and optical modelling indicate that the formation of a thin film of water on top of the hydrophilic scales increases their laminar thin film thickness, causing a shift towards violet/purple colour. Evaporation of the water film causes the metallic golden colour to return. This constitutes a remarkably rapid colour change (in the order of seconds), only limited by the speed of water film condensation and evaporation, that may serve as inspiration for new dynamically coloured materials and sensors.</span></p>
