    Bacterial contribution to genesis of the novel germ line determinant oskar

    Leo Blondel et al.
    Evidence suggests that the oskar gene, a critical germ line determinant in insects, was formed by fusion of bacterial and eukaryotic sequences at least 450 million years ago.

    Expansion of the fatty acyl reductase gene family shaped pheromone communication in Hymenoptera

    Michal Tupec et al.
    A fatty acyl reductase gene family expansion in the Hymenoptera crown group led to recruitment of novel pheromone-biosynthetic enzymes and is linked to evolution of pheromone marking behavior.

    Rarity is a more reliable indicator of land-use impacts on soil invertebrate communities than other diversity metrics

    Andrew Dopheide et al.
    Rarity metrics reveal pervasive negative impacts of agricultural land use on soil invertebrate communities, whereas widely-used richness and diversity metrics underestimate the magnitude of these impacts.

    The golden mimicry complex uses a wide spectrum of defence to deter a community of predators

    Stano Pekár et al.
    A mimetic complex composed of at least 140 species of ants, wasps, spiders, true bugs and treehoppers, all with conspicuous golden bodies, has been discovered.

    Three dimensional reconstruction of energy stores for jumping in planthoppers and froghoppers from confocal laser scanning microscopy

    Igor Siwanowicz, Malcolm Burrows
    Three dimensional reconstructions of the mechanical energy stores of jumping insects reveal how the miniaturized components interact and function.

    Amino acid synthesis loss in parasitoid wasps and other hymenopterans

    Xinhai Ye et al.
    The synthesis capability of some amino acids is lost during the insect evolution, and hymenopteran parasitoids can make up for these deficiencies by altering free amino acid concentrations in host.

    A large genomic insertion containing a duplicated follistatin gene is linked to the pea aphid male wing dimorphism

    Binshuang Li et al.
    The application of long-read sequencing to the pea aphid wing dimorphism system reveals genomic structural divergence as a genetic mechanism of adaptation.

    Nitric oxide radicals are emitted by wasp eggs to kill mold fungi

    Erhard Strohm et al.
    To protect their food and themselves against detrimental mould fungi, the eggs of a wasp species synthesize and emit remarkable amounts of gaseous nitrogen oxides that are highly effective antimicrobials.

    Folded gastrulation and T48 drive the evolution of coordinated mesoderm internalization in flies

    Silvia Urbansky et al.
    Functional recapitulation of a likely evolutionary gain in gene expression shows that two genes are sufficient to switch mesoderm cell internalization from stochastic cell ingression to coordinated epithelial invagination.

    Dynamic BMP signaling polarized by Toll patterns the dorsoventral axis in a hemimetabolous insect

    Lena Sachs et al.
    During the evolution of insect lineages, a signaling pathway dedicated to pathogen defense was co-opted for a new role in embryonic patterning.
