Thanks to micro-CT and www.antscan.info, you can now explore high resolution, 3D ant images from anywhere in the world. Fantastic work from Julian Katzke, Francisco Hita Garcia, @economo.bsky.social, Thomas van de Kamp and colleagues just dropped: www.nature.com/articles/s41...

‘I love midges because I know what their hearts look like’: is the passion for taxonomy in danger of dying out? Insect taxonomist Art Borkent has described and named more than 300 species of midges but fears his field of science is dying out, despite millions of insects, fungi and other organisms waiting to be ...

A 170-year-old flat wasp specimen was recently restored using an inexpensive ammonia-based protocol. 🐝

This study provides the first modern redescription of this rare species.

From cabinets to collectomics: discovering females and primary larvae of Strepsiptera in a historical collection Natural history collections house material from centuries of collecting efforts. In the Phyletisches Museum Jena (PMJ), ca. 1 Mio specimens are deposited, some of them dating back as far as the 17th c...

Evolutionary biologist Prof. Dr Andreas Hejnol looks at panther worms (Hofstenia miamia) in a petri dish. Image: Nicole Nerger / Uni Jena

"Panther worms" (Hofstenia miamia) in a petri dish. The worms, which have existed for 550 million years, are among the first "Bilateria", symmetrically structured animals with a left and a right half of the body, just like mammals. Image: Nicole Nerger (/ Uni Jena

How did the anus evolve? Researchers led by evolutionary biologist Prof. Dr Andreas Hejnol from #UniJena, in collaboration with the University of Bergen, showed that in sea worms (Xenacoelomorpha), the sperm duct exhibits the same gene pattern as the later rectum.

European mole cricket (Gryllotalpa gryllotalpa)

European mole cricket (Gryllotalpa gryllotalpa). Their front legs are modified into digging legs, convergent like those of a mole. It was found during my last field trip with students from the University of Jena to Lake Trasimeno in Italy in June 2025.

The Paragenital Organ of Stylopidae (Insecta: Strepsiptera) and the Functional Incorporation of the Secondary Larval Exuvia In the insect order Strepsiptera, we identified a paragenital organ in the family Stylopidae that serves as a secondary genital organ for traumatic insemination. We show that the cuticle at the penet...
