    Ferreira et al. (2024) reconstruct the left forewing venation of Picogryllus carentonensis, reporting the presence of the venation pattern compatible with the pattern proposed by Josse et al. (2023) for crickets.
    Ferreira et al. (2024) reconstruct the anatomy of the internal parts of the genitalia of a male specimen of Picogryllus carentonensis, and evaluate the tempo and mode of evolution of the family Oecanthidae, arguing that the family dates back to the Upper Jurassic.
    While describing structures interpreted as a grasshopper ootheca (egg pod) and eggs from the John Day Formation, Oregon, United States, Lee et al. advocate the use of the ootaxonomic nomenclatural system for description of insect egg fossils.

    Taniguchi et al. (2024) study the microstructure and distribution of sensilla from the antennae of Gerontoformica gracilis, and find that G. gracilis already had sensilla used by extant ants for detecting alarm pheromones and for distinguishing nestmates from intruders, and was capable of social chemical communication through pheromones used by modern ants.

    General research


    Evidence of the presence of distinct damage patterns on seeds from the Permian (Asselian) Shanxi Formation (China), interpreted as produced by insects with well-developed ovipositors (possibly members of Palaeodictyopteroidea), is presented by Santos, Wappler & (2024).
    A study on the taxonomy and taphonomy of insects fossils from Alderton Hill (Gloucestershire, United Kingdom), providing evidence of the presence of a diverse insect fauna (including representatives of 12 orders, 21 families, 24 genera and 21 species) during the Toarcian Oceanic Anoxic Event, is published by Swaby et al. (2024).
    A study on mine damage on gymnosperm specimens from the Middle Jurassic Jiulongshan Formation (China), probably produced by members of basal lineages of polyphagan beetles, monotrysian moths and tenthredinoid sawflies, is published by Xiao et al. (2024), who argue that the evolution of the mining associations of insects with gymnospermous plants during the Jurassic was likely caused by the appearance of new, more foliose plant lineages that provided more accessible food resources for mining insects.
    A study on the ecology of the Aptian insect fauna from the Nova Olinda Member of the Crato Formation (Brazil) is published by Bezerra & Mendes (2024), who interpret the studied insect fauna as living in an environment similar to modern long-standing wetlands, dominated by dominanted by fully terrestrial taxa, and relatively richer in palaeopterans than insect faunas from the Yixian and Zaza formations.
    Storari et al. (2024) compare the preservation of mayfly and orthopteran fossils from the Crato Formation and mayfly fossils from the Upper Jurassic Solnhofen limestones (Germany), interpreting the differences of the preservation of the studied fossils as indicative of the presence of microbial mats during the fossilization of insects from the Crato Formation.
    Evidence indicating that the radiation of the flowering plants mitigated insect extinction (especially during the Cretaceous period) and drove the origination of insects (especially during the Cenozoic) is presented by Peris & Condamine (2024).
    Loewen et al. (2024) describe a diverse amber deposit from the Maastrichtian strata from the Big Muddy Badlands (Canada), preserving fossils of representatives of seven arthropod orders and at least 11 insect families, and interpret the studied assemblage as providing evidence of a faunal turnover among insects prior to the Cretaceous–Paleogene extinction event.
    Eight insect specimens (members of Apocrita and Brachycera, members of the families Libellulidae, Pentatomidae and Bibionidae, and three indeterminate insects), representing the first insect fossils from Serbia reported to date, are described from the Miocene Valjevo-Mionica Basin by Lazarević & Milivojević (2024).
    An assemblage of subfossil remains of insects, dominated by diverse beetles, is described from the Late Pleistocene strata from the Lebed site (Altai Republic, Russia) by Gurina et al. (2024), who interpret the studied insects as indicative of humid climate which was significantly colder than modern climate in the studied area.
