My research interests are focused on macroecology, biogeography and systematics of species-rich moth communities. I am methodologically interested in light trapping with UV lamps and (UV) photography.
I am curating the insect collections at the Phyletisches Museum in Jena where I am also designing exhibitions. I also am voluntarily managing invasive plant species in the region and am testing appropriate methods.
My model groups are the species-rich moth clades of Geometridae (looper moths) and Arctiinae (tiger moths and woolly bears). The work has a focus on Central and South America, where thousands of species occur, many of them still undescribed. I carried out field studies mainly in Ecuador, Peru and Costa Rica (see papers below). All collected material is carefully prepared and permanently stored in the museum where it is available for further study, for examle on impacts of global heating. Some important projects are shortly presented in the following.
A project on pollination networks of Arctiinae and Sphingidae moths, bees and bats in NW Ecuador in collboration with Sara Leonhardt and Alex Keller in a DFG research unit has started in 2022. See reassembly website and below.
A DFG project Diversity and key traits of moths along a complete elevational gradient in the Peruvian Andes has started in September 2022. Yenny Correa Carmona is the PhD student has recently started the third field trip. The project is carried out together with PIs Marcell Peters, Alexander Keller and Ingolf Steffan-Dewenter. Felipe Yon, Juan Grados and Gerardo Lamas are our counterparts in Peru. Miles Silman, Adrian Forsyth and Alejandro Lopera are also collaborators. Here is a link to the ANDIV website.
The major objective of the project bundle is to contribute to the understanding of the broad scale drivers of holometabolous insects and their microbiomes. Lepidoptera are among the “big four” clades of holometabolous insects, and they play key roles as pollinators, defoliators and prey, yet factors determining their diversity in the tropics are poorly understood. Elevational gradients offer “natural experiments” for diversity studies, and they are far less influenced by large-scale biogeographic patterns than latitudinal gradients. The species-rich Lepidoptera clades Geometridae and Arctiinae are selected as model groups because they are phylogenetically unrelated and that differ in many traits such as body size and colouration.
For the first time, moths will be sampled quantitatively (attraction to light) along a nearly complete elevational gradient in the tropical Andes. A research collection with ca. 30,000 moth specimens and a DNA-barcode library with ca. 3,500 species will be established that will become available for long-term research. We will use UV photography and automated segmentation software for image analysis and determination of morphometric traits for all species. The data set will allowus to analyse diversity patterns and to investigate changes in selected functional traits of the moths along the elevation gradient.
A DFG project Plant-pollinator interactions: Diurnal and nocturnal pollinators in DFG FOR Reassembly started in 2022. PIs are Sara Leonhard (Munich), Alexander Keller (Munich) and I. The Jena group has performed a field study that investigates the differences of the moth faunas between canopy and understorey in primary and secondary forest; we investigate moth traits (including proboscis length) and test the methodology - using mini switch LepiLED lamps in combination with chloroform traps and extended rain protection. Dennis Böttger was in the field already for two times, and PhD student Ugo Dinizis intensively working in the project.
We have systematically compared LED lamps in field studies in Jena, i.e. UV lamps against mixed radiation lamps, and lamps that differ in radiation flux. Julia Niermann manuscrpt was published in 2022 in the European Journal of Entomology. It shows that microhabitat can have a larger influence on the samples than the lamp type. In 2021, Dennis Böttger and Rachit Singh carried out another study in the Jena Forest in order to compare the understorey and canopy moth fauna. Rachit also has tested three different types of traps. Analyses are ongoing. We are also producing new species lists for the region and compare the data with >60 year old sampling data.
In 2021, we published a paper on a large behavioural experiment with more than 6000 moth individuals (95 species) carried out in the last two years. We showed that short wave radiation, in particular UV and blue radiation is most attractive for the insects (Insect Conservation and Diversity). We conclude that outdoor lighting should have no UV radiation (as still found in metal halide lamps) and very low proportions of blue radiation (e.g. LED with low colour temperatures). From the viewpoint of an insect, red light is ideal.
We have started experiments for the AMMOD project, including a new lamp setup that allows standardized photography of moths. Paul Bodesheim, Dimitri Korsch and colleagues use artificial intelligence to identify moth species. A prototype of a camera trap has been insalled in 2020 in an orchard meadow in Jena and is constantly monitoring. Vivian Holzhauer has started her Master thesis in 2023. She will compare moth communities recorded with photos as compared to communities collected with classic methods. A new BMBF project (Lepidoptera monitoring) starts in November 2023.
Work on Eois is a longterm taxonomic project. Eois is an exceptionally diverse genus of looper moths (Geometridae). So far, around 210 species were described in the Neotropical region, but the actual species number is likely to be far more than 1000 species – so most of them still have to be described scientfically. This is a long-term taxonomic project. Similar projects were carried out and published for Callipia and Hagnagora. From field work in Costa Rica, Ecuador and Peru thousands of individuals are available for studies in the collections in Jena. I am currently sorting new material from SE Peru, so far around 150 species with different Barcode Index Numbers (BINs). Constantin Stephan will write his Master thesis about Eois.
In 2019, Leidys Murillo-Ramos et al. published an extensive study with 2000 terminal taxa of geometrid moths – by far the most comprehensive phylogenetic study of the group and one of the largest in Lepidoptera. Further detailed studies on New World Geometridae and on the subfamily Sterrhinae were published by us shortly after this. Due to a grant from the Finnish Academy of Sciences to Pasi Sihvonen (Helsinki), the project will be further extended towards an even and global coverage with the aim to include all known Geometridae genera in the years 2020 to 2023. I will continue the excellent collaboration with Pasi, Leidys, Niklas Wahlberg (Lund) and many others. Leidys as first author published another paper about the new geometrid subfamily Epidesmiinae
We are currently testing color traps with different colors and color combinations in Ecuador, Peru and Germany. The master thesis of Janeth Renteria has a focus on wild bees. The main colors we are testing are blue, yellow, purple and white. The study is conducted near Jena over a period of six months. The aim is to investigate which taxa can be best attracted with which colors and how strong seasonal fluctuations are. Janeth Renteria has finished the field work for her master thesis, testing different colours and colour combinations.
