Anthidium is a genus of bees often called carder or potter bees, who use conifer resin, plant hairs, mud, or a mix of them to build nests. They are in the family Megachilidae which is cosmopolitan in distribution and made up of species that are mostly solitary bees with pollen-carrying scopa that are only located on the ventral surface of the abdomen. Other bee families have the pollen-carrying structures on the hind legs. Typically species of Anthidium feed their brood on pollen and nectar from plants. Anthidium florentinum is distinguished from most of its relatives by yellow or brick-red thoracic bands. They fly all summer and make the nests in holes in the ground, walls or trees, with hairs plucked from plants.
The Bombini are a tribe of large bristly apid bees which feed on pollen or nectar. Many species are social, forming nests of up to a few hundred individuals; other species, formerly classified as Psithyrus cuckoo bees, are brood parasites of nest-making species. The tribe contains a single living genus, Bombus, the bumblebees, and some extinct genera such as Calyptapis and Oligobombus. The tribe was described by Pierre André Latreille in 1802.
Fibla carpenteri is an extinct species of snakefly in the Inocelliidae genus Fibla. F. carpenteri is named in honor of the paleoentomologist Dr Frank Carpenter, for his vast knowledge and interest in Raphidioptera.
Pseudosiobla campbelli is an extinct species of sawfly in the family Tenthredinidae that is known from early Eocene Ypresian stage lake deposits near the unincorporated community of Horsefly, British Columbia.
Palaeovespa is an extinct genus of wasp in the Vespidae subfamily Vespinae. The genus currently contains eight species: five from the Priabonian stage Florissant Formation in Colorado, United States, two from the middle Eocene Baltic amber deposits of Europe, and one species from the late Paleocene of France.
Anthidium scudderi is an extinct species of mason bee in the Megachilidae genus Anthidium. The species is solely known from the late Eocene, Chadronian stage, Florissant Formation deposits in Florissant, Colorado, USA. Anthidium scudderi is one of only four extinct species of mason bees known from the fossil record, and with Anthidium exhumatum, one of two species from the Florissant Formation.
Eriocampa tulameenensis is an extinct species of sawfly in the family Tenthredinidae that is known from early to early middle Eocene lake deposits near the small community of Princeton, British Columbia in the Similkameen region.
Paleolepidopterites is a collective genus of fossil moths which can not be placed in any defined family. The included species were formerly placed in the leaf-roller family Tortricidae and are known from fossils found in Russia and the United States. The collective genus contains three species: Paleolepidopterites destructus, Paleolepidopterites florissantanus, and Paleolepidopterites sadilenkoi, formerly placed within the genera Tortrix and Tortricites respectively. The three species were formally redescribed and moved to the new collective genus by Heikkilä et al. (2018).
Hydriomena? protrita is an extinct species of moth in the family Geometridae, and possibly in the modern genus Hydriomena. The species is known from late Eocene, Priabonian stage, lake deposits of the Florissant Formation in Teller County, Colorado, United States. It was first described by Theodore Dru Alison Cockerell in 1922.
Protostephanus is an extinct genus of crown wasp in the Hymenoptera family Stephanidae known from an Eocene fossil found in the United States of America. The genus contains a single described species, Protostephanus ashmeadi placed in the stephanid subfamily Stephaninae.
Eulithomyrmex is an extinct genus of ant in the formicid subfamily Agroecomyrmecinae. The genus contains two described species, Eulithomyrmex rugosus and Eulithomyrmex striatus. Eulithomyrmex is known from a group of Late Eocene fossils which were found in North America.
Aphaenogaster donisthorpei is an extinct species of ant in formicid subfamily Myrmicinae known from a Late Eocene fossil from North America. A. donisthorpei was one of two Aphaenogaster species described in the 1930 paper.
Aphaenogaster mayri is an extinct species of ant in formicid subfamily Myrmicinae known from a series of Late Eocene fossils found in North America. A. mayri was one of two Aphaenogaster species described in a 1930 paper by Frank M. Carpenter.
Aphaenogaster longaeva is an extinct species of ant in formicid subfamily Myrmicinae known from a solitary Eocene or Oligocene fossil found in North America. A. longaeva was one of five insect species described by the paleoentomologist Samuel Hubbard Scudder in an 1877 paper.
Archiponera is an extinct genus of ant in the formicid subfamily Ponerinae. The genus contains a single described species, Archiponera wheeleri known from several Late Eocene fossils which were found in North America.
Calyptapis is an extinct bombini genus related to bumblebees with one described species Calyptapis florissantensis. It is known only from the Late Eocene Chadronian age shales of the Florissant Formation in Colorado. The genus and species were described by Theodore Dru Alison Cockerell in 1906.
Holcorpa is a genus of extinct insects in the scorpionfly order Mecoptera. Two Eocene age species found in Western North America were placed into the genus, H. dillhoffi and H. maculosa.
Gyaclavator is an extinct genus of lace bug in the family Tingidae known from a fossil found in North America. The genus contains a single species, Gyaclavator kohlsi.
Florissantia is an extinct monotypic genus of planthopper in the dictyopharid subfamily Dictyopharinae. The single species, Florissantia elegans, was described by Samuel Hubbard Scudder (1890) from fossils found in the Florissant Formation of Colorado.
Polystoechotites is an extinct parataxon of lacewings in the moth lacewing family Ithonidae. The taxon is a collective group for fossil polystechotid giant lacewing species whose genus affiliation is uncertain, but which are distinct enough to identify as segregate species. Polystoechotites species are known from Eocene fossils found in North America and is composed of four named species Polystoechotites barksdalae, Polystoechotites falcatus, Polystoechotites lewisi, and Polystoechotites piperatus, plus two unnamed species. Three of the described species are known from fossils recovered from the Eocene Okanagan Highlands of Washington State, while the fourth is from Colorado.
