Κόνιτσα, Ελλάδα, 22-28 Ιουλίου 2025

Organization
Supported by

The Greek Summer School is revolutionizing Orthoptera research in Europe by integrating bioacoustics with modern tools and collaborative networks. Participants will:

Learn to record and identify Orthoptera species through sound.

• Gain hands-on experience with specialized audio equipment and analysis tools.

• Contribute data to open platforms like xeno-canto.org and Observation.org.

• Help expand sound databases, improving machine learning models and community engagement.

Grasshoppers, crickets, and katydids play a crucial role in ecosystems such as:

Biodiversity indicators – Their sensitivity to habitat changes helps monitor environmental health.

Key species in food webs – Serving as prey and herbivores, they sustain entire ecosystems.

Fascinating insects – Their diverse songs and adaptations reveal the wonders of nature.

Orthoptera communicate through stridulation, making their calls:

Essential for species identification – More reliable than visual traits.

Key to understanding behavior and ecology – Revealing mating patterns, territoriality, and more.

A valuable conservation tool – Helping assess populations and habitat changes.

Greece is a biodiversity hotspot for Orthoptera, offering:

400 species – 35% of Europe’s total.

140 endemic species – Found nowhere else on Earth.

Diverse landscapes – Mountains, islands, and microclimates create ideal habitats.

Conservation urgency – Nearly half of the endemic species face extinction due to habitat loss, climate change, and overgrazing.

Lectures

The TEOSS (Transforming European Orthoptera Sound System) project is a scientific initiative aimed at improving Orthoptera species recognition in Europe through sound recordings. With 1,229 Orthoptera species identified, of which 696 (66%) produce meaningful sounds, the project focuses on training volunteers, creating a meta-database, and developing automatic recognition models currently achieving 60% accuracy. Its objectives encompass biogeographical research, soundscape analysis, conservation efforts, citizen science, and acoustic identification technologies, with a particular emphasis on Mediterranean regions and capturing sound frequencies between 3 and 120 kHz. This introduction will review the milestones of the project and introduce the main characteristics of the Orthoptera group.

Observation.org emerges as a fundamental platform for citizen science, demonstrating significant impact with its annual collection of 32 million observations. The TEOSS (Training for the European Orthoptera Sound System) project is an exemplary case study, illustrating the synergistic potential of collaboration between professional researchers and citizen scientists. The presentation explains how TEOSS aims to strategically use Observation.org’s extensive network of observers to increase the database of European orthoptera sounds that can be used to feed the TEOSS AI model. The protocol for uploading observations to Observation.org and linking to sound files in Xeno Canto is outlined, thus showcasing an innovative methodology for data collection and dissemination in the scientific community. The overall goal is to demonstrate how initiatives such as TEOSS substantially contribute to the advancement of scientific knowledge through the integration of citizen participation and cutting-edge technologies. This approach not only improves data collection, but also encourages public participation in scientific efforts, potentially leading to more comprehensive and diverse data sets in the field of Orthoptera research.

What do you need to record Orthoptera, and what makes a good sound recording? There are many ways to record sound—even a smartphone can capture decent audio. The quality you need depends on your purpose. Are you recording for fun, personal learning of species, or scientific research? A loud cricket may require less precision than an ultrasonic singer. High-end recording equipment can be costly, but there are budget-friendly options to get started. In this presentation, you’ll explore key recording tools, from affordable choices to professional gear, helping you find the right setup for your needs.

What are the main characters in the songs of Orthoptera and how to view and measure them digitally? Orthoptera songs are defined by pulse rate, frequency, duration, and rhythm, all of which can be analyzed using audio software. Various programs allow you to visualize, edit, and measure recordings, with spectrograms revealing frequency details and slowed playback aiding in detecting subtle or ultrasonic elements. Software also enables cropping, noise reduction, and measurement of time and frequency characteristics. Freeware solutions are often sufficient for analysis, with “Audacity” being an excellent choice for beginners. More advanced tools offer deeper insights, but basic features are enough for effective study and species identification.

How many Orthoptera species inhabit Greece and how many Epirus? The lecture will present a panorama of the local Orthoptera species fauna, their habitats and tips for their identification in the field.

This talk will explore how AI and bioacoustics can support biodiversity conservation, despite the challenges of deploying these systems across diverse environments. Deep learning techniques for analyzing animal sounds, with a focus on insect monitoring, will be discussed. Key obstacles in real-world deployment will be addressed, along with strategies to scale these approaches for greater impact.

The lecture will integrate the work of GSS-OSS in a broader conservation context. We will discuss the threats of European Orthoptera, the main legal and policy tools we dispose as scientists to halt their decline, focusing on the provisions of the recent Nature Restoration Regulation. An interactive discussion on the threats and conservation actions known by the participants will follow to close the section.

Fieldwork

A two-hour fieldwork in the surroundings of the venue is planned, in the former agricultural fields of “Anagnostopoulio Center”. Three student groups will be formed. You will grab and test different gears, with the help of our three tutors. The session aims at your familiarization with the sound equipment, exploring how it functions and conducting the first recordings. Do your best! A Questions & Answers (Q&A) session after lunch will consolidate your first field experience.

Starting this morning session, after a short bus trip (40 min), we will reach Lake Zaravina, a small (30ha) but beautiful lake, creating humid local conditions in the surrounding grasslands. During the course, we will follow a strict protocol to obtain a diverse range of Orthoptera sound recordings. Only well-identified and properly annotated recordings are suitable for automatic species recognition. To ensure accuracy, we will encourage collecting photographic material or other forms of evidence for identification, along with detailed metadata. We will then move to a temporary pond at agricultural land, where the famous Epirus dancing grasshopper (Chorthippus lacustris) holds a small population, for further recordings.

Students can follow a night session, recording more inconspicuous nocturnal species in a path near Aoos river, after the stone bridge of Konitsa. The site will be reached on foot.

We will conduct a two-hour fieldwork with Orthoptera recordings, following the protocols of F2. The stone forest of Monodenri is a unique open forest in a carstic geological bedrock with special rock formations and unknown Orthoptera fauna to be discovered! 

We will travel by bus (15 min) towards Kallithea village. We will stop before the village to follow a short path (400m) towards a chapel, through abandoned agricultural fields and scrubland. A one-hour night walk, recording more inconspicuous nocturnal species. 

We will move by bus (1.30h) to reach Grammos Mt to the north. We will conduct Orthoptera recordings at the mountainous grasslands above 1,400 m near the village of Aetomilitsa, following the protocols of F2.

The team will move by bus (15 min) to reach Saint Athanasios chapel. A one-hour night walk, recording more inconspicuous nocturnal species following a path towards the chapel, through a grassland with sparse old-growth oaks.

Laboratories

The course comprises five labs, one for every day, lasting 2-3 h each. The first short lab is an interactive session aimed at equipment use problem-solving. All the following lab sessions comprise editing of sound recordings, analysis and upload of recordings to Xeno-canto, including all relevant metadata. All recordings collected in the morning field sessions as well as from the previous night walks should be treated in the labs. The objective of the labs is to consolidate the knowledge learned during the fieldwork, contribute valuable data for research and species recognition.

Seminars

Our team will start a nice trip with small stops (1.30h) towards the famous Vikos gorge. Dr. H. Papaioannou, biologist and coordinator of the Vikos-Aoos Geopark will accompany us on a unique tour presenting the geological value of the Global UNESCO Geopark, as well as the local history and culture of Konitsa and Zagori. The bus tour will end at the “stone forest”, a particular semi-open forest intermingled with rock tower formations at the edge of Vikos Gorge. Keep distance to the edge! Vikos Gorge is one of the deepest gorges of the world reaching 900 m in depth!

In this session, the floor is yours. As many of you might already work with Orthoptera or sounds in nature or both, you may wish to share your project with your peers. A mini congress of 10-12 min presentations of participants is launched. It is voluntary. You are engaged only if you wish to. Any kind of Orthoptera research, without necessarily involving acoustics is eligible, and any kind of research involving sound recordings, without necessarily involving Orthoptera. If we have many applications, we should choose the most relevant. You will be asked on the registration form, if you would like to present your project, and provide a title and a short abstract (100 words). That would be nice to create the next network of young Orthopterologists and sound experts in Europe! Dare! We wait for your input!

Social program

Friday 25 July
13:00-15.30

After a short bus trip (20min) from the “stone forest” back to Monodendri village, it is time for a traditional lunch at the central square of Monodendri. We will taste the famous Zagori’s traditional cheese pie under the name “Kassiopita”. Free time will be allowed to enjoy the local architecture, or visit the famous Monastery of Saint Paraskevi (15 min walk) dated from 1413 and belonging to the Patriarchate of Constantinople, with a splendid view of Vikos Gorge or visit the photo exhibition at Rizarios Exhibition Center (entrance with a ticket around 5€). Back to Konitsa venue for a little rest and labwork!   The same night, we will go near Kalithea village and have dinner at the local tavern, to have an idea of how cozy non-touristic spots can be as well!

Saturday 26 July

After a one-hour night walk at Saint Athanasios chapel, the bus will wait for us to drive us to the nearby village of Piklari (or Pigi). It is a great religious festivity in honor of Agia Paraskevi (Saint Paraskevi) and this involves a traditional fiesta in the village square, with local music (klarino), wine, local dances and souvlaki. It is an event that you must experience. [Food/drinks costs not covered].
