Plecia is a genus of March flies (Bibionidae) comprising many species, both extant and fossilised.
Many fossil species have been assigned to Plecia with ages dating from the Cretaceous (Campanian) through the early Pleistocene (Gelasian): [6]
Revision of the Bibionidae fossil record from the Oligocene of Germany by Skartveit and Wedmann (2021) included the redescription of a number of Plecia species. [7]
Crassostrea is a genus of true oysters containing some of the most important oysters used for food. Some species in the genus have been moved to the genus Magallana.
The family Prophalangopsidae are insects belonging to the order Orthoptera. They are the only extant members of the superfamily Hagloidea. There is only one extant genus in North America, where they are known as grigs, four genera in Asia, and many extinct genera.
The Ptychopteridae, phantom crane flies, are a small family of nematocerous Diptera. Superficially similar in appearance to other "tipuloid" families, they lack the ocelli of the Trichoceridae, the five-branched radial vein of the Tanyderidae, and the two anal veins that reach the wing margins of the Tipulidae. They are usually allied with the Tanyderidae based on similarities of the mesonotal suture, this group being called the Ptychopteromorpha.
Bibionidae is a family of flies (Diptera) containing approximately 650–700 species worldwide. Adults are nectar feeders and emerge in numbers in spring. Because of the likelihood of adults flies being found in copula, they have earned colloquial names such as "love bugs" or "honeymoon flies".
Platypezidae is a family of true flies of the superfamily Platypezoidea. The more than 250 species are found worldwide primarily in woodland habitats. A common name is flat-footed flies, but this is also used for the closely related Opetiidae which were included in the Platypezidae in former times.
Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 1959.
Cercopidae are the largest family of Cercopoidea, a xylem-feeding insect group, commonly called froghoppers or spittlebugs. They belong to the hemipteran suborder Auchenorrhyncha.
Bibio, March flies or St. Mark's flies, is a genus of flies (Diptera).
Penthetria is a genus of March flies (Bibionidae).
Prehistoric Lepidoptera are both butterflies and moths that lived before recorded history. The fossil record for Lepidoptera is lacking in comparison to other winged species, and tending not to be as common as some other insects in the habitats that are most conducive to fossilization, such as lakes and ponds, and their juvenile stage has only the head capsule as a hard part that might be preserved. Yet there are fossils, some preserved in amber and some in very fine sediments. Leaf mines are also seen in fossil leaves, although the interpretation of them is tricky. Putative fossil stem group representatives of Amphiesmenoptera are known from the Triassic.
The Allenby formation is a sedimentary rock formation in British Columbia which was deposited during the Ypresian stage of the Early Eocene. It consists of conglomerates, sandstones with interbedded shales and coal. The shales contain an abundance of insect, fish and plant fossils known from 1877 and onward, while the Princeton Chert was first indented in the 1950's and is known from anatomically preserved plants.
The Coldwater Beds are a geologic formation of the Okanagan Highlands in British Columbia, Canada. They preserve fossils dating back to the Ypresian stage of the Eocene period, or Wasatchian in the NALMA classification.
Cephalops is a genus of flies belonging to the family Pipunculidae.
Plecia canadensis is an extinct species of Plecia in the fly family Bibionidae. The species is solely known from Early Eocene sediments exposed in central southern British Columbia. The species is one of twenty bibionid species described from the Eocene Okanagan Highlands paleobiota.
Eudorylas is a genus of flies in the family Pipunculidae.
Plecia avus is an extinct species of Plecia in the March fly family Bibionidae and is solely known from Early Eocene sediments exposed in central southern British Columbia. The species is one of twenty bibionid species described from the Eocene Okanagan Highlands.
