“…For the new fossil presented here it is not easy to evaluate which characters represent plesiomorphies or convergent characters. Hence, as in other fossil larvae (e.g., HAug et al 2019a;zippeL et al 2022, the new larva has characters that are known from modern relatives, but not necessarily in the same combination. A more precise interpretation is not possible with the available characters.…”

“…This statement is, of course, tricky as it relates to a purely typological type of thinking. Yet, it is a general phenomenon for fossils to show a mixture of characters known from separate modern lineages (e.g., Haug et al 2019a; Luque et al 2019; Zippel et al 2022, 2023). There are two major factors for this phenomenon: plesiomorphies and convergences.…”

“…An important difference to plotting head together with stylets is that the occupation of the morphospace of the modern larvae is larger than that of the Eocene larvae. Yet, some Eocene larvae plot outside the range of the modern larvae, emphasising again that the Eocene fauna also differs from the modern fauna concerning insect larvae [ 115 ].…”

Lacewings have been suggested to be a relict group. This means that the group of lacewings, Neuroptera, should have been more diverse in the past, which also applies to many ingroups of Neuroptera. Psychopsidae, the group of silky lacewings, is one of the ingroups of Neuroptera which is relatively species-poor in the modern fauna. Larvae of the group Psychopsidae, long-nosed antlions, can be easily identified as such in being larvae of antlion-like lacewings without teeth in their stylets (=compound structure of mandible and maxilla), with empodia (=attachment structures on legs) and with a prominent forward-protruding labrum. Therefore, such larvae can also be recognised in the fossil record. An earlier study demonstrated a decline in the morphological diversity of long-nosed antlion larvae over the past 100 million years. Here, we report several dozen new long-nosed antlion larvae and expand the earlier quantitative study. Our results further corroborate the decline of silky lacewings. Yet, a lack of an indication of saturation indicates that we have still not approached the original diversity of long-nosed antlions in the Cretaceous.

Beetle larvae represent important components of the modern-day fauna. This should have been the case in the past as well. Yet, fossil beetle larvae are rare, or at least are rare in the literature, as identifying a beetle larva to a narrower taxonomic group is very challenging. This is even more complicated if prominent features have evolved convergently in several lineages. Yet, even in such cases, an ecological interpretation of the fossils is possible if the convergent character is coupled to a specific life habit. For example, different, not closely related, beetle larvae that possess setiferous processes. We here report on three beetle larvae, one from Miocene Mexican and two from Cretaceous Kachin amber, Myanmar. These larvae possess setiferous processes, most similar to the processes of modern representatives of Cucujiformia, especially of the groups Endomychidae, Erotylidae, Cerylonidae and Coccinellidae. Considering the shape of the entire habitus, we see the most similarities between the new larvae and the modern larvae of Endomychidae. However, the new larvae and the larvae of modern representatives differ in certain aspects, most prominently in the body size. The fossils are smaller than their extant counterparts with setiferous processes. Hence the fossils could represent larvae of Endomychidae, but the case remains unclear. Despite this uncertainty, we suggest a lifestyle of the fossil larvae as fungus-eaters on rotting wood. This lifestyle is not only known from extant larvae of Endomychidae, but also from other larvae with similar processes.
