  • 06/2020 – Our paper with Conrad on Phanaeini macroevolution got published in the Biological Journal of the Linnean Society. This study investigates the systematics and evolution of the tribe Phanaeini with a focus on the various ecologies of these beetles. Indeed, while most species are coprophagous, some lineages are necrophagous and others are even myrmecophilous. We provide new insights into this ecological evolution with a comprehensive timetree of the tribe.

  • 11/2019 – We just published a study on preliminary of red-eye pigmentation in skippers and its possible evolutionary ties with diel activity. This study represents the first step toward a more in-depth investigation of the link between these biological patterns. Interestingly, we recover many independent isntancs of red-eye pigmentaitona cross the skipper tree of life and diel activity seems to be connected to this atonishing feature.

  • 06/2019 – Digitization of all Calosoma ground beetles and most of tiger beetles (Cicindelidae) is in the works thanks to our two volunteers! This project is completely new and represented the first digitization setup at the MHNG for insect collections. It includes a Canon 80D with an EFS-60mm macro lens setup on a Kaiser stand and with several LED lamps for lighting. All digitized specimens receive a unique MHNG label and are entered into our FileMaker database for archiving with a high-resolution habitus picture including a color chart and scale. We are already updating the system to improve some aspects, for instance the Canon 80D will be replaced by a Canon 90D, the Kaiser stand will be replaced by one with a motorized ramp for stacking and lighting will be replaced by flexible Kaiser LED vertical lamps. We are also crossing fingers to migrate our database to Specify next year.

  • 06/2019 – Some fieldwork in Corsica helped to sample Calosoma sycophanta that was out in large numbers following the outbreak of Lymantria dispar across the island. This spectacular beetle is far from being common and except during years like this one is a very difficult beetle to see. Other beetles of interest were Calomera littoralis and the endemic Percus. No sign of the three Carabus species found in Corsica, despite intense efforts to find C. genei in the central montane areas.

  • 04/2019 – Our new paper on Anaeini butterflies is out in Molecular Phylogenetics and Evolution! This has been one of the most challenging studies for us going through many rounds of reviews. In the end the paper is a really interesting in depth study of this tribe, with particular focus on the historical biogeography of the group in the Neotropics and the role of host-plant shifts in its evolution. Have a look at the paper in the Publications page.

  • 04/2019 – Several collecting sessions in the Alps to sample specimens for an upcoming project on Carabinae systematics using HyRAD-X, a novel phylogenomic method developed in Geneva at the Museum. We were looking for multiple representatives of species groups in Calosoma, Carabus and Cycrhus, the three European genera of the subfamily. We did manage to find Carabus and Cychrus but it is apparently too early for Calosoma.

  • 02/2019 – Our paper on the remarkable convergent evolution of giant damselflies is in early view in Evolution. This study relied on morphological and molecular phylogenies to show that disjunct lineages of giant damselflies do not share a common ancestor but rather originated well after the break-up of Gondwana. They have evolved similar ecologies and behaviours including a stunning diet of orb-weaver spiders that they pluck from the webs using stationary flight. The result of our study have also found an echo in the press!

  • 11/ 2018 – Our study on the evolution of the Charaxes solon complex is just out in the Biological Journal of the Linnean Society. What was suspected for decades is supported by different lines of evidence. Specifically, each major biogeographical group is a valid species. We raise back to species status three subspecies: Charaxes echo from the Greater Sunda Islands, Charaxes hannibal from Wallacea and Charaxes lampedo from the Philippines. An interesting development not only for the taxonomy of the group but also for the biogeography of the genus as a whole since this is the third Charaxes lineage that colonized South East Asia from Africa.

  • 09/2018 – Multiple small fieldwork sessions in Normandy and the Alps in France to look for tiger beetles and other ground beetles but also to check historical collections. In particular, we had the chance to be warmly welcomed by Frédéric Durand and François Fournier of the Société d’Histoire Naturelle Alcide-d’Orbigny in Aubière near Clermont-Ferrand (SHNAO). They were kind enough to accept our request to visit Roger Naviaux’s tiger beetle collection under very short notice. This is a remarkable collection in terms of curation, type and specimen numbers.

  • 09/2018 – Harlan Gough’s paper on the phylogeny of tiger beetles is finally out in Systematic Entomology! It took us an enormous amount of time to gather all the molecular data that has been generated for decades by various research teams in the world. The tree will be useful to many people working on this group by providing a first large-scale phylogenetic framework for tiger beetles.

  • 09/2018 – Athena Lam who was finishing her PhD with Michael Balke in Munich just published a really nice study in Molecular Ecology. She was looking at fine-scale phylogeographic structure in New Guinean water beetles. Our results support the idea that ecology has an important impact on the evolution of lineages but the story is more complicated than we though as is often the case with these beetles! Here are the original drawings of Philaccolilus species from Michael’s 2000 paper on the genus:

  • 08/2018 – Chris Johns from the Kawahara Lab just published the biggest study of his PhD before graduating! A beautiful paper published in Proceedings B on the biogeography and host-plant diet evolution in the charismatic Hawaiian Philodoria micro-moths. We look at divergence times in detail and suggest that this group of moths is one of the oldest lineages to have colonized ancient Hawaiian islands that are now submerged in the middle of the Pacific Ocean.

  • 05/2018 – Our latest paper on water scavenger beetles just came out in Molecular Phylogenetics and Evolution. A comprehensive methodological (to some degree) study of Oocyclus historical biogeography. This genus comprises extremely cool water beetles that have a fairly modified morphology that allows them to cope with extreme habitats such as waterfalls and rock seepages. Their current distribution is puzzling as some species are found in India, others in Southeast Asia and the rest in the Neotropics. Our study suggests a rather unusual biogeographical pattern possibly obscured by extinction. Read more about it in the Publications page.

  • 04/2018 – Back from a two-week expedition in French Guiana looking for butterflies, beetles and moths. We stayed at the Nouragues CNRS station in the heart of the Amazonian rainforest where we sampled along trails and in the canopy. Many interesting species of skippers, satyrines and tiger beetles among other insects collected during this trip.

  • 02/2018 – Just back from a long expedition across the Marquesas islands in French Polynesia. We were looking for the rare endemic butterfly Libythea collenettei (Marquesan snout butterfly or Papillon à museau des Marquises in French). Only five specimens have ever been collected to date, and the most recent sightings on Nuku Hiva and Ua Pou date back from 2001. Unfortunately we could not find this species. The disruption of natural habitats might be a reason for its possible extinction.
