50 million-year-old fossil assassin bug has unusually well-preserved genitalia

The fossilized insect is tiny and its genital capsule, called a pygophore, is roughly the length of a grain of rice. It is remarkable, scientists say, because the bug’s physical characteristics – from the bold banding pattern on its legs to the internal features of its genitalia – are clearly visible and well-preserved. Recovered from […]

Researchers describe new fossil leafhoppers

INHS researchers Chris Dietrich and Michael Jared Thomas have described two new extinct fossil leafhoppers—Eoidiocerus emarginatus and Archipedionis obscurus—embedded in 37–44 million-year-old Baltic amber. Both fossils are part of the PRI Paleontology Collection. Read the full paper here: https://zookeys.pensoft.net/articles.php?id=21976

Researchers describe new Crato Formation insects

Check out this new paper by Vladimir Makarkin, Sonja Wedmann, and PRI Paleontology Collection curator Sam Heads: A systematic reappraisal of Araripeneuridae (Neuroptera: Myrmeleontoidea), with description of new species from the Lower Cretaceous Crato Formation of Brazil: http://ow.ly/iQvP30ikJ2M.

Researchers describe new species of lacewing

Today we bring you a newly described species of lacewing: Parababinskaia elegans gen. et sp. nov. from the late Aptian Crato Formation of Brazil. The holotype specimen—housed in the INHS Paleontology Collection—was described by Vladimir Makarkin, Sam Heads (INHS), and Sonja Wedmann in a recent issue of the journal Cretaceous Research.

Froghopper from Montana

Our team collected many interesting new fossils during fieldwork in Montana last month. Here team member Susan McIntyre poses with a beautifully preserved spittlebug wing she discovered at one of the excavation sites in the Oligocene Renova Formation. Spittlebugs (also called froghoppers) are insects of the superfamily Cercopoidea (order Hemiptera). They feed by sucking juices […]

New study reveals evolutionary patterns of grasshoppers, crickets, and katydids over the past 300 million years

INHS orthopterist and paleontologist Sam Heads was co-author on a recently published study determining the evolutionary relationships of the grasshoppers, katydids, and crickets. The current study is based on genetics rather than morphological characteristics. The Origin of Grasshoppers, Katydids, and Crickets: A New Study Resolves the Evolutionary Tree of the Orthoptera

Decades-old amber collection offers new views of an ancient world

INHS Paleontologist Sam Heads, Jared Thomas, and Yinan Wang found a new pygmy locust embedded in amber. In a paper released today, the species was described and named Electrotettix attenboroughi, in honor of Sir David Attenborough. Attenborough narrated a video about their research. To find out more, read this article by the U of I News Bureau.

INHS entomologists comment on fossil stick insects

Following the discovery of fossil stick insects by a team of Chinese and French scientists, INHS Paleontologist Sam Heads and Illinois State Entomologist Chris Dietrich were contacted by National Geographic to comment. Heads told National Geographic that the discovery of fossilized plant mimicking insects, “is yet more tantalizing evidence of early insect-plant coevolution.”

Ancient ‘fig wasp’ lived tens of millions of years before figs

INHS Paleontologist Sam Heads found an ancient fig wasp that pre-dates any known fig trees. According to Heads, “This is a tiny parasitic wasp, it’s the smallest fossil wasp found in this particular deposit and it’s the oldest representative of its family. More importantly, it’s possible that this wasp was fig-associated, which is interesting because it’s Early […]
