First record of Brachyponera chinensis in Germany!

An all-star student-team of the Rabeling Lab discovered a new invasive ant species in Germany. In 2024, Max Härtel, David Grunicke, and Benni Palm discovered Brachyponera chinensis (photo: A. Bellersheim, SMNS) , the Asian needle ant, in the Wilhelma Zoo-Botanical Garden in Stuttgart. A year later, the Asian needle ant was also found during a BioBlitz in the Rosenstein Park in Stuttgart. Finding these ants outside of greenhouses in two consecutive years suggests that colonies are capable of surviving the local winter.  Therefore, the spread of this new invasive ant needs to be monitored closely.

To describe their discovery, Max, David, and Benni teamed up with colleagues from the Natural History Museums in Stuttgart and Frankfurt. The scientific paper reporting their findings just appeared in the journal Zootaxa.

Congratulations to Philipp Bauer!

In a beautiful presentation Philipp shared the results of his Master's thesis research with the lab. Philipp decided to study the biology of the minute thief ant Solenopsis fugax. Interestingly, this species has been discovered and described 228 years ago but to this day the biology of this species is not known in detail. Interesting hypotheses exist that Central European Solenopsis fugax represent multiple species, one of which is a cletoparasite whereas the other one is a predator. Philipp systematically tested these hypothesis and can now paint a clearer picture about the biology of these tiny thief ants. Philipp's project is a great example how clarly laid out hypotheses and behavioral tests can results into fasvinatng new insights of a species that has been known to entomologists for a couple of centuries.

Beautiful work, Philipp, and congratulations on successfully defedning your Master Thesis!

David Grunicke successfully defended his Bachelor's Thesis!

Today, David presented his research that he accomplished as part his Bachelor's Thesis to the lab. David conducted an impressive amount of work revising the taxonomy of army ant relatives, i.e., ants in the subfamily Dorylinae, from the South Pacific Island archipelago Vanuatu. David used an integrative approach to taxonomy delineating multiple new species. The forthcoming study is going to shed more light on the surprisingly rich ant biodiversity of Vanuatu. Stay tuned for more... 

Congratulations to David, for successfully completing a very substantial Bachelor's Thesis!

Congratulations to Sarah von Adelmannsfelden!

Sarah successfully finished her Master's Studies at the University Hohenheim. Her thesis work explored the evolution of social parasitisms in vespine wasps.  Sarah's study resulted into a beautiful thesis, which should see the light of publication soon. Thank you for suggesting this thesis topic, which gave all of us an opportunity to learn about the "other social insects."  

We also want to congratulate Sarah on receiving a prestigious fellowship from the Studienstiftung des Deutschen Volkes! Sarah will continue her scientific career at the University of Freiburg in Peter Biedermann's lab.  

We are sad to see Sarah move on, but we wish her much success for doctoral dissertation in Freiburg!  It was was wonderful to have her as a lab member and we learnt a lot, not only about wasps!

 Congratulations Sarah on finishing a beautiful Master's Thesis and being awarded an excellent fellowship!

A new social parasite species from North America

The North American inquiline social parasites in the genus Monomorium are among the rarest ants in the world! The three previously known species are only known from the original collections at their type localities dating back as  early as 1893. in  collaboration with Stefan Cover, we described a new, forth inquiline social parasite species that was discovered in New Mexico. Very little is known  about the biology of these ants. Should YOU be so lucky and find a mixed colony of Monomorium ants and their social parasites, please take careful notes so will learn more (or something!) about the biology and life history of these mysterious creatures.

Breaking Bad! (Boll)

To get a break from the usual hustle & bustle of the semester, we secluded in Bad Boll. In addition to peace and quiet, we found a welcoming staff, excellent food, awesome hiking trails, amazing fossils, and excellent ants. The lab retreat was a real treat for all of us!

New paper about evolution of the hyperdiverse ant subfamily Myrmicinae

A new paper in collaboration with Matt Prebus at ASU came out in Systematic Biology. This fossil-calibrated phylogeny infers the biogeography and evolution of the ant subfamily Myrmicinae, tests conflicting hypotheses about the evolutionary relationships between tribes in hyperdiverse Myrmicinae, and resolves the timing of major evolutionary events in the subfamily. Interestingly, the study shows that the placement of a single fossil (i.e., Manica andrannae) has a broad-scale effect on the overall divergence timing in the entire subfamily Myrmicinae.

New study reveals diversity and evolution in Acromyrmex leaf-cuttings ants

Congrats to Daniela Mera-Rodríguez, who published the next chapter of her doctoral dissertation! This paper carefully dissects the diversity and evolutionary history of the Acromyrmex octospinosus species complex. Daniela's study reveals that all previously described species and subspecies in this complex belong to a single, panmictic, biological species, Acromyrmex octospinosus. In addition, its social parasite, Acromyrmex insinuator, was also supported as a "good" species, which speciated in direct sympatry from its host while sharing the same nest  space approx. 1 Million years ago. Daniela's integrative study approach solved a biological puzzle which has  been discussed in the literature for more than 100 years!

Congratulations to Tobias Pfeifer!

Tobi is the 1st Bachelor student to graduate from our new lab at the University of Hohenheim!  He developed a wonderful thesis project that went far beyond the scope of a Bachelor's Thesis. Tobi explored the diversity and evolutionary history of Strumigenys ants in the South Pacific Island archipelago Vanuatu. He reconstructed the evolutionary history of Strumigenys ants using phylogenomic markers and discovered several new species endemic to Vanuatu. He (and all of us) are very excited about the study results, which Tobi will explore in  more detail during his Master's.  Excellent work, Tobi, and best of skills for further developing your scientific career. Your are off to a great start!  

Congratulations, Tobi!

New paper about ant-fungus co-evolution in Science

As part of a team of international collaborators, we reconstructed a comprehensive phylogeny for the mutualistic fungi that are cultivated by fungus-growing ants. The new study infers the co-evolutionary dynamics of ants and fungi in detail and suggests that the ant-fungus mutualism emerged after the end-Cretaceous extinction.

Inaugural Entomology Field Trip to the Vinschgau in South Tirol!

In close collaboration with Georg Petschenka (U. Hohenheim) and Robert Trusch (State Museum of Natural History Karsruhe), we launched a student excursion to the Vinschgau in South Tirol. The students (and we) had great fun hunting for insects all day and (some) all night long. What made this field trip special was the participation of a group of expert Lepidopterologists, who have been exploring this region for decades. They happily shared their entomological wisdom, and we all learned a lot about light trapping techniques, as well as butterfly mounting and identification. What an awesome field trip!  We hope to able to offer this field course again next summer semester!

First confirmed inquiline social parasite species in dolichoderine ants

Some research projects are like fine red wine... After years of intensive labor, Stefan Cover and I finally published the description of four new inquiline social parasite species in the odorous ants, the subfamily Dolichoderinae. These new species are from North America and interestingly, they exhibit different social parasitic life history strategies.

The paper appeared in ZooKeys:
