Inside the Tangled Bank of Arthropods
We unravel the molecular-genetic mechanisms of key traits within the broader fields of herbivory, endosymbiosis, and reproductive isolation. We use interdisciplinary approaches to dissect the mechanistic basis of these complex traits.

>> Our study on complex cryptic co-infections of Spiroplasma in European Myrmica ants is now published : https://doi.org/10.1111/mec.70341 . The project officially began over beers in the garden of Thomas before covid-19 happened. Throughout the years, we sampled over 75 colonies of 7 Myrmica species. We developed an in-house protocol to generate and carefully analyze ONT amplicon read data. Together with Sanger and Illumina sequence data of experimental lab colonies, we show that Myrmica queens and workers are typified by a variety of Spiroplasma co-infections. We further uncover that infection heterogeneity is dependent on caste in Myrmica ruginodis, a common species in Europe. We also present evidence that one particular Spiroplasma variant may display stable maternal transmisision within Myrmica for the last 7 million years!
>> Earlier this year, I had the privilege of presenting our research at INRAe (Montpellier) and the Max Planck Institute for Chemical Ecology (Jena). I also had a wonderful time at the EMBO workshop on Molecular mechanisms of selfish elements and strategies.
>> Jolien De Smet has recently joined our team! She is a research technologist and will contribute to our ongoing molecular-genetic experiments in mites and ants. Diego has recently started a new position - we wish him all the best!

>> Together with Felipe Kauai, we wanted to better understand how Wolbachia infection persists upon loss of CI in haplodiploid hosts. In our study, we focused on both CI loss through the evolution of host suppression and through the dysfunction of cif operons. Please go HERE for the article!
>> Ernesto Villacis‐Perez visited our lab and sampled several Tetranychus populations in the dunes of West Flanders.
>> Gerben Debruyn started his post-doc project in our lab! He will start to unravel how phasmid eggs interact with parasitoids and symbionts.
>> Margarita, Emma, and Siebe also gave their first presentations at ESEB2025!

>> Spearheaded by Thomas, our study on the interaction between the yellow meadow ant Lasius flavus and the root aphid Anoecia zirnitsi is published. We demonstrate that L. flavus strongly increases the aphid eggs’ protection against insect predators and fungal pathogens. Go here for more information: https://doi.org/10.1098/rsos.250217
>> We were also visited by Charles Robin (University of Melbourne) and Kosuke Kataoka (TUAT). Kosuke gave a great research seminar and we had a lot of fun discussing various ideas and ongoing experiments.
