“…In the Cretaceous amber Neuroptera, larvae of stem-group Chrysopidae (green lacewings) have some spectacular morphological modifications, such as dramatically elongate legs, leaf-like thoracic and abdominal lobes, or extremely elongate, highly setigerous tubular processes on the thorax and abdomen, and these specialized characters are associated with predation, mimesis and camouflage in these species, respectively [29][30][31][32]. Some recently described Cretaceous myrmeleontiform larvae also had highly disparate morphological traits convergently evolved with chrysopoid larvae in relation to predatory habits [33][34][35]. Other, unrelated Cretaceous lacewing lineages had elongate mouthparts, in families which today lack such features, and were specializations for a variety of feeding strategies but including pollen and nectar [36][37][38][39].…”

Mantidflies (Mantispidae) are an unusual and charismatic group of predatory lacewings (Neuroptera), whereby the adults represent a remarkable case of morphological and functional convergence with praying mantises (Mantodea). The evolutionary history of mantidflies remains largely unknown due to a scarcity of fossils. Here, we report the discovery of a highly diverse palaeofauna of mantidflies from the mid-Cretaceous (lowermost Cenomanian) of Myanmar. The raptorial forelegs of these mantidflies possess highly divergent morphological modifications, some of which are unknown among modern mantidflies, e.g. the presence of forked basal profemoral spines or even the complete loss of foreleg spine-like structures. A phylogenetic analysis of Mantispidae reveals a pattern of raptorial foreleg evolution across the family. The high species diversity and disparate foreleg characters might have been driven by diverse niches of predator–prey interplay in the complex tropical forest ecosystem of the mid-Cretaceous.

“…Myrmeleontiformia is a larger ingroup of Neuroptera including antlions as well as some closer relatives, together known as the antlion-like lacewings. Myrmeleontiformian larvae are well represented in the fossil record, especially in 99 million-year-old Cretaceous amber from Myanmar, also known as Kachin amber, Burmese amber or Burmite (e.g., Wang et al 2016;Badano et al 2018;Haug et al 2019aHaug et al , 2019bHaug et al , 2020Herrera-Flórez et al 2020;Pérez-de la Fuente et al 2020).…”

Larvae, and especially fossil larvae, are challenging to deal with from a purely taxonomic view. Often one cannot determine which species the larvae belong to. Yet, larvae can still contribute to various scientific questions. Especially morphological traits of a fossil larva can be highly informative for reconstructing character evolution. Also the occurrence of specific larval types and larval characters in time and the disappearance of such forms can well be reconstructed also without being able to narrow down the phylogenetic relationship of a larva very far. Here, we report two new beetle larvae preserved in Baltic amber which are identified as representatives of Scraptiidae, based on an enlarged terminal end (‘9th abdomen segment’); this is only the third record of such larvae. In comparison to modern forms, the terminal ends of the two new fossil larvae is even larger in relation to the remaining body than in any known larva. Unfortunately, our knowledge of such larvae in the modern fauna is very limited. Still, one of the two already known fossil larvae of Scraptiidae also has a very long terminal end, but not as long as those of the two new fossils. These three fossil larvae therefore seem to possess a specific morphology not known from the modern fauna. This might either mean that they (1) represent a now extinct larval morphology, a phenomenon well known in other euarthropodan lineages, or that (2) these forms represent a part of the larval phase not known from modern day species as they have not been described yet; such cases occur in closely related lineages. In any case, the fossils expand the known diversity of larval morphologies.
