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.
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.
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 from plants through their straw-like mouthparts and are capable of jumping impressive distances. Their common name comes from their habit of surrounding themselves in protective froth as nymphs.
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.
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.

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.”
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 Cretaceous, about 115 to 120 million years old. That’s a good 65 million years or so prior to the first occurrence of figs in the fossil record.”
