Hi, I am Viktor! Pleased to meet you, I entomologist and paleontologist originally from Ukraine, now working in Spain, after a decade in German academia. I study amber fossils, Jurassic of Australia, Insect decline, climate change in the pas, and gleefully use Synchrotrons. Languages: EN, ES, DE, UA

Slope of the volcano is covered by the succulents and dry shrubbery Interactions of higher temperature and lower oxygen saturation with Chironomidae  flies growth and resulting size. Arrow from low temperature to high, shows that flies are growing smaller at the higher temperature, as well as growing smaller at the lower oxygen concentration in the water, where they larvae developing - from Baranov et al., 2025  https://resjournals.onlinelibrary.wiley.com/doi/10.1111/een.13469 CT scan reconstruction of the fossil of Caddisfly larva (Lepidostomatidae) from Baltic amber, showing general body shape and upclose images of the head.

Me llevó siete años darme cuenta de que las pupas no estaban mal conservadas, sino que tenían un disco al final del cuerpo.
Un pequeño momento “¡Eureka!”, pero probablemente el más grande de mi carrera. ✨ @davidperis.bsky.social

Nuestro análisis filogenético sugiere un origen austral con una dispersión posterior hacia el norte.
Y deja una lección importante: el registro fósil está sesgado hacia el norte global.
Muchas piezas perdidas de la historia evolutiva aún yacen en el hemisferio sur.

Este fósil es el Podonominae (y Chironomidae) más antiguo del hemisferio sur.
En el norte (Mongolia y Siberia) hay fósiles de unos 180 millones de años.
Curioso, ya que la mayor diversidad actual está en el sur. ¿Se originaron en el norte o en el sur? 🤔

Telmatomyia pertenece a la subfamilia Podonominae, que hoy vive en Sudamérica, Australia, Sudáfrica y Nueva Zelanda: un ejemplo clásico de vicariancia.
Cuando Gondwana se fragmentó, estas poblaciones quedaron aisladas y evolucionaron de forma independiente (Brundin, 1966).

Sabíamos que los fósiles pertenecían a Chironomidae — mosquitos no picadores, parientes lejanos de los mosquitos.
Hoy existen unas 8.000 especies vivas.
Son indicadores esenciales de la calidad del agua dulce y, sorprendentemente, también de los movimientos continentales. 🌍

Las pupas (etapa intermedia como la crisálida de una mariposa) fueron descubiertas por mi colega y coautor Robert Beattie, del Museo Australiano.
Ofrecen una mirada única a la evolución temprana de los jejenes no picadores, un grupo ecológicamente clave.

Estudiamos seis fósiles —tanto pupas como adultos en emergencia— que mostraban una estructura en forma de disco terminal.
Este rasgo, típico de hábitats influenciados por las mareas, se creía exclusivo de especies marinas.
Pero Talbragar demuestra que también existía en ambientes de agua dulce.

Telmatomyia significa “mosca de aguas quietas”.
Es el registro más antiguo de mosquitos no picadores del hemisferio sur, hallado en los famosos lechos de peces de Talbragar, una instantánea fósil de la vida en un lago que cubría parte de Nueva Gales del Sur hace unos 150 millones de años.

we have published a really bizzare jurassic #fossil midge today, with cool "sucker" on the end of abdomen, might be of interest for some of you @franzanth.bsky.social @jopabinia.bsky.social @jacquelyngill.bsky.social @stephenbheard.bsky.social

took me 7 years to realize the pupae weren’t just poorly preserved — they had a disc at the end of their body.
tiny “Eureka!” moment — but probably the biggest of my career. ✨ @nataliajagielska.bsky.social @flygirlnhm.bsky.social

Our phylogenetic analysis suggests a southern origin — with later northward dispersal.
It’s also a reminder: fossil records are biased toward the Global North.
Many “missing pieces” of evolutionary history are still buried in the Southern Hemisphere.

This fossil is the oldest Podonominae (and Chironomid) from the Southern Hemisphere.
Northern Hemisphere fossils (Mongolia, Siberia) are ~180 million years old.
Curious, since most modern diversity is southern — did they originate in the north, or the south? 🤔

Telmatomyia belongs to the subfamily Podonominae, found today across South America, Australia, South Africa & New Zealand — a classic case of vicariance.
As Gondwana broke apart, these insect lineages were separated and evolved independently (Brundin, 1966).

We knew the fossils belonged to Chironomidae — non-biting midges, distant cousins of mosquitoes.
Today, there are ~8,000 living species.
They’re key indicators of freshwater quality — and, as it turns out, of continental movement too. 🌍

The pupae (like the “chrysalis” stage in butterflies) were discovered by my colleague and co-author Robert Beattie from the Australian Museum.
They offered a rare glimpse into the early evolution of non-biting midges — one of the most ecologically important fly groups.

We studied six fossil specimens — both pupae and emerging adults — all showing a terminal disc structure.
This feature, used by larvae in tide-influenced habitats, was once thought to occur only in marine species.
But the Talbragar fossils prove it also existed in freshwater environments!

Telmatomyia means “fly from standing water.”
It’s the oldest record of non-biting midges from the Southern Hemisphere — from the famous Talbragar Fish Bed, a fossil snapshot of life in a lake that covered parts of New South Wales ~150 million years ago.

Este viernes 3 de octubre a las 20:00h en la Casa del Cine en Almería daré una conferencia sobre la paleontología en el cine, para hablar principalmente de la representación de los dinosaurios y otros bichos extintos en las películas.
¿Alguien por Almería este viernes?
