“…Furthermore, Shi et al (2012) clearly mentioned a volcanic environment in which Myanmar amber was buried. The paleobiological record also supports this: one anaxyelid woodwasps that laid eggs in recently burned wood (Ortega-Blanco et al, 2008) and the abundant gleicheniacean ferns trichomes, an invasive group of ferns after wildfires (Pérez-de la Fuente et al, 2012), became embedded in Spanish amber. Furthermore, one bostrichid coleopteran from genus Stephanopachys Waterhouse, 1888, that is particularly attracted by young trees damaged by wildfire, became embedded in French amber (Peris et al, 2014a).…”

International audienceThe intense study of coleopteran inclusions from Spanish (Albian in age) and French (Albian–Santonian in age) Cretaceous ambers, both of Laurasian origin, has revealed that the majority of samples belong to the Polyphaga suborder and, in contrast to the case of the compression fossils, only one family of Archostemata, one of Adephaga, and no Myxophaga suborders are represented. A total of 30 families from Spain and 16 families from France have been identified (with almost twice bioinclusions identified in Spain than in France); 13 of these families have their most ancient representatives within these ambers. A similar study had previously only been performed on Lebanese ambers (Barremian in age and Gondwanan in origin), recording 36 coleopteran families. Few lists of taxa were available for Myanmar (Burmese) amber (early Cenomanian in age and Laurasian in origin). Coleopteran families found in Cretaceous ambers share with their modern relatives mainly saproxylic and detritivorous habits in the larval or adult stages, rather than wood-boring behavior. Fifteen of the coleopteran families occur in both the Lebanese and Spanish ambers; while only five are present in both Spanish and French. Considering the paleogeographic proximity and similarity of age of the Spanish and French ambers, the small number of taxa found in common at both areas is surprising. The ancient origin for the Lebanese and Spanish ambers, the paleogeography (including some barriers for terrestrial biota) and the local paleohabitats are factors that may explain the dissimilarity with the French specimens. Wildfires are believed to be a more likely cause of resin production during the Cretaceous than infestation by beetles. Current knowledge of the beetle species found in the Cretaceous ambers is introduced

“…It is a true living fossil, the sister group of nearly all the other extant saproxylic false click‐beetles, the last survivor of a formerly widespread clade. Interestingly, it is the second living fossil insect associated with the western Nearctic incense cedar ( Calocedrus decurrens ), the other one being the cedar wood wasp ( Syntexis libocedrii ), the only living representative of the family Anaxyelidae, otherwise known from Cretaceous deposits in Spain, Russia and China, including the Jehol biota (Ortega‐Blanco et al., ).…”

Palaeoxenus sinensis Chang, Muona & Teräväinen sp. nov. (Coleoptera, Eucnemidae) is described on the basis of a Cretaceous larva found from the Yixian Formation in Huangbanjigou, Liaoning Province, China. The only previously known member of this clade is a southern Californian endemic, Dohrn's elegant eucnemid beetle (Palaeoxenus dohrni), a species that develops in conifers, especially the incense cedar (Calocedrus decurrens). The new find proves that the highly specialized main eucnemid lineages had evolved 123 Mya, before the main radiation of the angiosperms and probably as an adaptation to development in gymnosperms.

“…The reason is that Anaxyelidae comprises just one species ( Syntexis libocedrii ), surviving from a previously larger Mesozoic–Cenozoic group and S. libocedrii has a very specialized lifestyle, where the female oviposits only into recently burnt or still burning cedar wood (Zhang & Rasnitsyn ; Ortega‐Blanco et al . ; Davis et al . ).…”

Insect–plant interactions are important to understanding the evolutionary mechanisms responsible for most of the diverse plant‐feeding insects. We aggregated data on sawfly–host plant associations and other resource associations from existing sources to address the following questions: (i) Is there a general correlation between host diversity and sawfly species richness? (ii) Is the pattern of host plant use consistent across sawfly lineages? and (iii) Is there a phylogenetically significant shift in species richness among sawflies? Our analysis comprised 8567 sawfly species, including 2087 species with host plant and other records. In total, there were 2126 records of host usage for sawflies, the overwhelming majority of which were sawflies using angiosperms as resources. Rosales are used by most of the species in sawfly families or subfamilies. We found that there was a strong correlation between the number of host plant orders and the species richness of sawfly families and subfamilies. To examine the points at which sawflies have experienced significant shifts in species richness, we compared sister taxon species richness. Several positive and negative shifts in species richness among sawflies were related to their range of host plant usage and specialized niche, respectively. In general, we found that most of the sawfly families and subfamilies used several orders as host plants, but mainly core eudicots, although some families or subfamilies were specialized on pteridophytes or gymnosperms.
